Case.
S220, according to the history case history sample determine that the dependence between each state of an illness description and each action scheme is closed
System.
S230, the current state of an illness description of acquisition.
Obtaining current state of an illness description includes：Receive the state of an illness description that user currently inputs.Exemplarily, user currently inputs
State of an illness description can be doctor according to the state of an illness description of the oral account input of patient or doctor according to before patient just
The current state of an illness description that doctor's record is got from the case sample of patient；It can also be doctor according to the oral account input of patient
State of an illness description has carried out state of an illness description after state of an illness inquiry etc., does not limit herein.It is understood that the current state of an illness
Description can describe the identical state of an illness that can also be with being got in case sample with the state of an illness described in history case history sample and describe
It is different.
S240, the history case history sample traveled through according to the dependence, judged whether and the current state of an illness
The action scheme of association is described, if performing S250；Otherwise S270 is performed.
Scheme is put according to state of an illness description and the action related to state of an illness description, each moment or each stage is capable of determining that
State of an illness description, determine the medical diagnosis path described in the history case history sample, sum up the description of each state of an illness and each action
Incidence relation between scheme and diagnostic result, you can sum up medical diagnosis experience, base is established to set up medical guidance path
Plinth.In the present embodiment, get after current state of an illness description, the history case history sample where current state of an illness description can be traveled through, sentenced
It is disconnected to whether there is the action scheme associated with the description of the current state of an illness, can effectively it comb out complete described in history case history sample
Diagnosis scheme, preferably sum up medical practice knowledge
If S250, in the presence of action scheme associate with the current state of an illness description, obtain and the current state of an illness description
And target state of an illness description corresponding with the action scheme, and described target state of an illness description as the current state of an illness
Next level state of an illness description.
Exemplarily, it will can be associated using the current state of an illness being originally taken description as root node with the description of the current state of an illness
Each action scheme as each of the root node connect side, each target state of an illness corresponding with each action scheme description determined
It is used as each leaf node of root node.I.e. each node is state of an illness description, and each line is action scheme.If leaf section
Point also means that after the corresponding state of an illness description of the leaf node without follow-up line, does not have follow-up action scheme.
This operation can be described by the current state of an illness, and the action scheme related to the description of the current state of an illness, it is determined that currently
Next level state of an illness description of state of an illness description.It is understood that there may be in different history case history samples same
The state of an illness is described, and it is probably identical or different action scheme to be described corresponding with the same state of an illness, and therefore, the current state of an illness is retouched
State the state of an illness description that there may be one or more next levels.
S260, after the target state of an illness being described as new current state of an illness description, return to execution S240.
In the present embodiment, in order to sum up medical scheme complete in history case history sample, to the disease of each level
Feelings description is required for performing same operation, that is, needs to judge whether also there is follow-up action side after the state of an illness is described
Case.Accordingly, it would be desirable to after the target state of an illness being described as new current state of an illness description, it is necessary to repeat according to state of an illness description and
Dependence between action scheme travels through the history case history sample where current state of an illness description, judges whether and current disease
The operation of the action scheme of feelings description association, to determine whether the description of the current state of an illness is that the state of an illness of last level is described.
Can progressively it be determined from the description of the current state of an illness according to the description of the current state of an illness and each action scheme using the above method
Go out the state of an illness description of last level, so as to sum up the medical diagnostic method of complete set, effectively summarize each history disease
The medical practice knowledge gone through in sample.
S270, the state of an illness description for recording different levels, and corresponding action scheme, structure are described with the association levels state of an illness
Build out medical navigation model.
Exemplarily, tree structure can be built according to the description of each state of an illness and each action scheme, and then by constructed tree
Shape structure is used as medical navigation model.Can be specifically that each node as the tree structure is described using each state of an illness, each
Action scheme is as the company side of the tree structure, then then initial state of an illness description, can close as root node according to root node
Join each action scheme determine the next level of root node the state of an illness description as root node leaf node, will with root node and respectively
The action scheme of child node association determines that the leaf node of leaf node connects side with it as even side, and so on, by
Step determines each node and even side, and being recorded in the tree structure, so that each in each history case history sample
The state of an illness describes to build complete tree structure with each action scheme.
S280, corresponding current income is described according to each state of an illness and each lower floor's state of an illness describes corresponding future action valency
Value, determines the corresponding current action value of each action scheme.
The state of an illness that current income is appreciated that to be arrived according to current collection is described, and has much assurance to provide diagnostic result.
During actual diagnosis, state of an illness description is abundanter may to be more conducive to providing diagnostic result, but is likely to increase as well state of an illness description
Diagnostic result is not had much affect afterwards.Do not point out what user's next step should do in view of current income, be to question closely
More symptoms, still allow patient to do a certain chemical examination or inspection.Therefore, work as to preferably determine that each action scheme is corresponding
Preceding action value, can comprehensively be considered with reference to whole diagnosis process, not only need to consider each state of an illness describe it is corresponding currently
Income, in addition it is also necessary to consider that the state of an illness describes corresponding each lower floor's state of an illness and describes corresponding future action value.It can such as build
One action cost function is used to guide the follow-up optimal course of action of doctor.Specifically, can be first according to the description pair of each state of an illness
The current income and each lower floor's state of an illness answered describe corresponding future action value, and construction action cost function is then based on institute
State action cost function and calculate the corresponding current action value of each action scheme.
Alternatively, it is described corresponding current income to be described according to each state of an illness and each lower floor's state of an illness describes corresponding following row
Dynamic value, construction action cost function, including：In record result, since the state of an illness description of lowermost layer, calculate successively and each
The state of an illness describes corresponding current action cost function；Wherein, if lower floor's state of an illness description is not present in the state of an illness description currently calculated,
Then determine to describe corresponding current revenue function with the state of an illness currently calculated according to the state of an illness description currently calculated, will currently calculate
State of an illness description the current action cost function of state of an illness description that currently calculates as described of the current revenue function；If
There is lower floor's state of an illness description in current state of an illness description, then each state of an illness is described to the future action of corresponding current income and action scheme
The addition of discounting of value, is used as the current action cost function of the state of an illness description currently calculated.Wherein, future action is worth
Discount can be next level state of an illness describe it is corresponding action value weighting.
Wherein, the state of an illness description of lowermost layer is designated as the state of an illness description of last level, is also last level leaf
Node.It should be noted that last level leaf node is also described subsequently without action scheme in the absence of lower floor's state of an illness.
In record result, since the state of an illness description of lowermost layer, calculate describe corresponding current action value letter with each state of an illness successively
Number, it can be understood as, since the leaf node of the lowermost layer for the tree that each state of an illness is described and each action scheme is constituted,
Current action value is calculated, and is traced back successively, the current action value of father node is calculated, until calculating the current of root node
Action value.
If lower floor's state of an illness description is not present in the state of an illness description currently calculated, it can be understood as the state of an illness description currently calculated
Subsequently without action scheme, last level leaf node of as current tree structure, then according to the state of an illness currently calculated
Description determines to describe corresponding current revenue function with the state of an illness currently calculated, you can to calculate the last of current tree structure
The current revenue function of one level leaf node, and the current action of the current revenue function as the leaf node is worth
Function.Similarly, if the state of an illness description currently calculated has lower floor's state of an illness description, it can be understood as the state of an illness currently calculated
Description have follow-up action scheme, be the tree structure root node or intermediate node, then can by the node it is corresponding work as
Preceding income is added with the discounting for future action value of action scheme, is used as the current action cost function of the node.
Exemplarily, the state of an illness that might as well obtain t describes st, and according to current collection to the state of an illness s is describedt, traversal should
The corresponding all possible action scheme a of state of an illness descriptiont, it is expressed asSo as to obtain next
The individual moment is that the t+1 moment all possible state of an illness describes st+1, similarly, st+1It can be expressed asWherein, n represents total kind number (quantity) of the state of an illness description at t+1 moment.
Assuming that at the t=1 moment, for s1In the presence of 4 kinds of action scheme a1, the state of an illness describes s1For " neck has lump ", this hour hand
To s1There is k kind action schemes a1, it is respectivelyFor example,For " whether coughing ", question closely patient there is provided
More symptoms；For " doing venous blood chemical examination, especially consult white blood cell count(WBC) ", it is proposed that lab work；" to have in neck
Lump, does biopsy, takes pathological section ", carry out pathologic finding；" to be PET in neck, looking at lump whether be metabolized partially
It is high ", carry out the image check of positron e mission computed tomography.The doctor now diagnosed can be from 4 kinds of action schemes
a1In select an execution.
If, taken action scheme in t=1 moment doctor suggestion patient" there is lump in neck, do biopsy, take disease
Reason section ", at the t=2 moment, biopsy report is completed, and the state of an illness describes s2Content can add, now s2Content may be
One of three kinds of situations below：For " neck has lump, and neck biopsy is without exception "；For " neck has lump, lymphohematopoietic tissue delivered
There is benign tumour "；For " neck has lump, and lymphohematopoietic tissue delivered has malignant tumour ".Calculate and correspond to respectivelyAnd
Current incomeAnd
If finishing biopsy, biopsy results are " lymphohematopoietic tissue delivered have malignant tumour ", and whole diagnosis process terminates, and does not have
Follow-up action scheme, i.e. a2=null.So it can now takeValue described as the current state of an illnessCorresponding current action valency
ValueValue, i.e.,If biopsy results are " neck biopsy are without exception ", then also
Need to check white blood cell count(WBC), verified, i.e. a2For examination white blood cell count(WBC).And the result of white blood cell count(WBC) is checked, have three
Plant possible, " normal ", " higher ", " relatively low ".Corresponding state of an illness description and income are respectively：For " neck has lump ", " it is as good as
Often ", " white blood cell count(WBC) is normal "；For " neck has lump, without exception, and white blood cell count(WBC) is higher "；For " neck has lump,
Without exception, white blood cell count(WBC) is relatively low ".Calculate and correspond to respectivelyAndCurrent incomeAndIf examination is white
After cell count, result is " white blood cell count(WBC) is normal ", and diagnosis process terminates, i.e. a3=null, then
It should be noted that only working as at=null, i.e., when describing no follow-up action scheme for the current state of an illness, currently
The state of an illness describes corresponding current action value Q (st,at=null)=rt。
If have follow-up action scheme for the description of the current state of an illness, the current state of an illness describes corresponding current action value can be with
It is indicated using equation below：Wherein, stRepresent the disease of t
Feelings are described or the description of the t kinds state of an illness；atRepresent that the state of an illness description with t or the t kind state of an illness describe stThe action side of association
Case；Q(st,at) represent that the state of an illness description of t or the t kind state of an illness describe corresponding current action value；r(st) represent t when
The state of an illness description at quarter or the t kind state of an illness describe stCorresponding current income；st+1Represent state of an illness description or the t at t+1 moment
+ a kind of state of an illness description；Represent that the state of an illness description with the t+1 moment or the t+1 kind state of an illness describe st+1The jth kind action of association
Scheme, j value is to be less than or equal to more than or equal to 1 and stThe positive integer of total kind of number of the action scheme of association；Represent that the state of an illness description with the t+1 moment or the t+1 kind state of an illness describe st+1And each action schemeMaximum in corresponding each current action value, γ isWeight, can be default normal
Number, specific value can be configured according to actual conditions, not limit herein.
For the state of an illness description of t, at next moment t+1 moment, the action scheme of multiple associations might have
at+1, whereinIn order to ensure to reach best diagnostic result, it is necessary in various action
SchemeIn select optimal course of action, makeMaximize, can be expressed asγ
It is constant set in advance, the discount rate for expressing future profits.Therefore,For under expression
The future action value at one moment is equal to how many current incomes.The current state of an illness describes corresponding current action valueCurrent action value=current income+future can be simply expressed as
What action was worth discounts.
During actually diagnosis, different lab works is different with the financial cost of inspection project and stand-by period etc.
All it is not quite similar.For patient demand of preferably fitting, optimal therapeutic scheme is sought in the acceptable scope of patient, can
To introduce the cost of activities factor when calculating action value.Specifically, corresponding current income is described and each according to each state of an illness
Lower floor's state of an illness describes corresponding future action value, construction action cost function, it may include：Obtain the action of current state of an illness description
Cost, and psychological utility function is built according to the cost of activities；Each state of an illness is described into corresponding current income and each lower floor disease
Feelings are described after the addition of discounting of corresponding future action value, subtract the psychological utility function, to construct current action value
Function.
For example, it is assumed that the cost of each action, it is fixed, can preset., can be for convenience of calculation
The value stipulations of cost of activities are between 0 to 1., may not be linear due to psychological feelingses of the cost to patient.It therefore, it can use
Shape is similar to the curve of sigmoid functions, to construct the psychological utility function of cost of activities, more relevantly to describe patient
For the psychological feelingses of cost.Assuming that when cost is close to 0, change of the patient to cost is insensitive；When cost is more than one
Mental threshold, during close to 1, complaint of the patient to cost is very big.Wherein, the specific value of mental threshold can according to urban district and
Situation is set, for example, can be 0.5.Now, when may illustrate that cost is around 0.5, change of the patient to cost may
It is most sensitive, and cost continues to rise, patient may be numb.
Exemplarily, the psychological utility function Psychological Utility based on cost of activities in the present invention, specifically
It can be expressed with equation below：Wherein, α and β is default constant, Cost (at) represent t
Cost of activities corresponding to action scheme.After the psychological effectiveness factor for adding cost of activities, corresponding current action value can be with
It is expressed asWherein, γ is the current action at t+1 moment
ValueWeighted value, γ specific value can be configured according to actual conditions, not limit herein.
Corresponding current revenue function is described with the state of an illness currently calculated according to the state of an illness description determination currently calculated, specifically
It may include：Each state of an illness in history case history sample describes and describes corresponding medical diagnosis on disease result, structure with the state of an illness
Build medical practice and summarize model；Model is summarized based on the medical practice and determines that the state of an illness with currently calculating describes corresponding disease
Sick diagnostic result, and calculate the probability distribution of at least one disease；According to the probability distribution of the disease, calculate with currently
The state of an illness of calculating describes the entropy of corresponding diagnostic result, and builds current revenue function according to the entropy.
Specifically, each state of an illness in history case history sample describes and describes corresponding medical diagnosis on disease with the state of an illness
As a result, it can describe each state of an illness in history case history sample as input to build medical practice and summarize model, by history disease
The probability of various diseases included in corresponding medical diagnosis on disease result and diagnostic result is described in example sample with the state of an illness
Distribution is instructed as output to default generation confrontation network (Generative Adversarial Networks, GAN)
Practice, obtain building medical practice summary model, sum up the clinical diagnosis decision-making experience of senior doctor.Wherein, generation confrontation net
Network (Generative Adversarial Networks, GAN) includes production model and discriminative model.
Exemplarily, in history case history sample each state of an illness description and describe corresponding disease with the state of an illness and examine
Disconnected result, builds medical practice and summarizes model, it may include：Target data in history case history sample is to default production
Model is trained；First data falsification is generated according to the production model after the completion of training, and according to the number of targets
According to this and first data falsification is trained to default duscriminant model；According to the production mould after the completion of training
Type generates the second data falsification, and according to discriminating knot of the duscriminant model after the completion of training to second data falsification
Fruit is adjusted to the parameter of the production model, regard the production model that default equilibrium condition is met after adjustment as medical science
Summary of experience model.Wherein, the target data includes the description of each state of an illness and describes corresponding medical diagnosis on disease with the state of an illness

Model is summarized based on the medical practice and determines that the state of an illness with currently calculating describes corresponding medical diagnosis on disease result,
And the probability distribution of at least one disease is calculated, can obtain current state of an illness description first, and the state of an illness is described
The medical practice that training completes is input to summarize in model, the medical practice summarize the state of an illness currently inputted is described into
Row processing, the output medical diagnosis on disease result corresponding with the state of an illness description currently calculated, and calculate the general of at least one disease
Rate distribution is shown.
In the present embodiment, current income rtOnly describe whether diagnostic result focuses on a few disease, it may also be said to
According to current collection to the state of an illness description have it is much assurance provide diagnostic result.Assuming that the disease quantity that is included in diagnostic result or
Person's species is fewer, and the probability for suffering from every kind of disease is higher, illustrates more sure to current diagnostic result, current income rtAlso
It is higher.Entropy is used in the embodiment of the present invention, to express current income rt.Wherein, the corresponding entropy of each disease type in diagnostic result
It can be calculated by below equation：Wherein, stRepresent t
State of an illness description collected by moment；dtRepresent that the state of an illness collected by t describes corresponding diagnostic result；Diagnostic result can
One or more diseases can be included,Represent that the state of an illness collected by t describes jth kind disease in corresponding diagnostic result；The probability of jth kind disease in diagnostic result is suffered from expression；Entropy(dt, st) represent with t collected by
The state of an illness describes the entropy of corresponding diagnostic result.
For example according to the limited state of an illness description being collected into, the diagnostic result of output shows that patient may suffer from five kinds
Disease type, wherein, the probability of every kind of disease type is 20% respectively.The entropy of this diagnostic result is Entropy (d1|s1)=-
1.0* (5*0.20*log0.20)=2.32, wherein logarithm log are bottom with 2.If then have collected more state of an illness descriptions, then
Diagnostic result, which is updated to patient, may suffer from two kinds of disease types, and probability corresponding with both disease types is respectively 20%
With 80%, at this moment the entropy corresponding to diagnostic result is Entropy (d2|s2)=- 1.0* (0.20*log0.20+0.80*
Log0.80)=0.72.In extreme circumstances, a kind of disease class may be only had by corresponding diagnostic result being described with the state of an illness of input
Type, probability is 100%, and at this moment the corresponding entropy of the disease type is 0.It follows that diagnostic result concentrates on a few
Disease type, entropy is lower.If diagnostic result only one of which disease, the assurance to diagnostic result is bigger, entropy is minimum, is
0。
If for the same state of an illness, we have collected a large amount of case histories.State of an illness description is extracted from these case histories
And diagnostic result, it is then based on medical practice and summarizes modeling statistics going out various related diseases in the diagnostic results of these case histories
The probability distribution of disease, calculates the entropy of the diagnostic result described for this state of an illness.Wherein, medical practice summarizes model
Output is to describe s with the state of an illnesstProbability p df (the d of each disease in corresponding diagnostic resultt|st), it can useRepresent, and then according to
pdf(dt|st) entropy of diagnostic result can be just calculated, in this, as current income rt。
It should be noted that entropy expression is meant that for the description of this state of an illness, there is much to the diagnostic result of output
Hold.In other words, if described for the same state of an illness, comprising a variety of diseases in the diagnostic result in history case history sample, or
Diagnostic result difference in the different history case history sample of person is very big, then illustrate the diagnosis described for this state of an illness, diagnosis
As a result difference is larger, and the assurance to diagnostic result is relatively low.But whether just the size of entropy is not offered as diagnostic result in itself
Really.Even if that is doctor is quite sure to diagnostic result, it must be just correct not ensure that diagnostic result.
The span of entropy is that, from 0 to+∞, entropy is smaller, and income is bigger.In order to rtSpan, be limited to
From 0 to 1 scope so that rtValue is bigger, and current income is bigger, can be rtIt is configured to minor function：
Exemplarily, clinical treatment path navigation table can be set, specifically can be by the row of navigational table point three, the content point of each column
It is not si、aiAnd Q (si,ai), that is, state of an illness description, action scheme and state of an illness description are corresponding with this action scheme
Current action value.Navigational table has some rows, a kind of s of correspondence per a lineiAnd aiCombination.Because the same state of an illness of correspondence is described
si, might have a variety of action scheme ai, specifically can be by aiIt is expressed as：Wherein, k is row
Total kind number (quantity) of dynamic scheme,Represent that i-th kind of state of an illness describes corresponding kth kind action scheme；Similarly,Represent the
The i kind state of an illness describes corresponding jth kind action scheme.So, strictly speaking, the content in navigational table per a line is s respectivelyi、
, can be based on the first training of medical experience of history case history sample after have collected a certain amount of history case history sample data
Model is summarized, has trained medical practice to summarize model, it is possible to the medical navigational table of filling.Specifically, can be from a case history
In, sort out the state of an illness and describe st, and diagnostic result dt.Wherein, diagnostic result dtIncluding one or more disease types.Remember that T is
The terminal in path is diagnosed, i.e., then current action value Q (sT,aT=null)=r (sT), wherein, aT=null represents whole diagnosis
Process terminates, and does not now have follow-up action scheme after corresponding state of an illness description；Current income can be formulated as：
It is then possible to according to the above-mentioned future action that corresponding current income and action scheme are described by each state of an illness
The calculation formula of current action value determined by valueOr
Consider the calculation formula of the current action value after the psychological factor of patient, the psychological utility function of additionInversely anti-upper moment was released from the terminal T moment
Action value, such as terminal T momentProgressively obtain
Corresponding current action is described with each state of an illness to be worth, until extrapolating the initial state of an illness describes corresponding current action value Q
(s1,a1)。
Same processing is all done to every a history case sample, first part of history case sample has been handled, has then handled
Second part of history case sample, and update the Q (s in navigational tablet,at), until having handled all history case samples.Can be with
Understand, with the development and the accumulation of clinical treatment experience of medical science, can constantly obtain new history case history Sample Refreshment
Medical navigational table.
S290, according to the current action value determine current optimal action scheme as current goal action side
Case, and determine based on each current goal action scheme and targeted yield the medical treatment navigation road in the medical navigation model

It is used as current goal action scheme, it may include：Action maximum in each current action value calculated is worth institute right
The action scheme answered, is used as current goal action scheme.That is, s is described corresponding to the same state of an illnesst, have a variety of action schemesEvery kind of current action value of action correspondence oneTake a variety of action schemes it is corresponding eachIn most
Big person, corresponding action schemeIt is exactly optimal course of action.
If increasing continuing several current state of an illness descriptions next level resulting after the action scheme of next step
The current income of state of an illness description is calculated, and the change of each obtained current income less, then may explanation increase action side
The state of an illness description of each next level after case is little for the influence of diagnostic result.Therefore, it is described based on each state of an illness description,
The action scheme and targeted yield associated with each state of an illness description is determined before medical guidance path, can also be included：Calculate
Each state of an illness describes corresponding current income, if the amplitude of variation of the corresponding current income of the state of an illness description of predetermined number is small
In predetermined threshold value, then the current income is regard as targeted yield；Or, calculate each state of an illness and describe corresponding current income, such as
The current income that each state of an illness description of the continuous predetermined number of fruit is corresponding restrains, then regard current income as targeted yield.
Wherein, predetermined number can be understood as the state of an illness description quantity can in advance be set according to actual conditions, example
It can be such as 3,4 or 5, not limit herein.Meanwhile, predetermined threshold value can also rule of thumb default setting or by user according to
Actual conditions are configured, and are not limited herein.
For example, it is assumed that the state of an illness description of initial input, start time is designated as, is represented with t=1, through each action scheme
Obtained final state of an illness description afterwards, at the time of being designated as diagnosis end, is represented with t=T, during whole diagnosis, calculates every
Current income r corresponding to one momentt, can specifically be calculated by equation below：Wherein, Entropy (dt|st) represent to describe corresponding each disease with the state of an illness of t
The entropy of type, if rt, rt+1..., rt+ΔAmplitude of variation, constantly less than predetermined threshold value, such as default constant, τ, then should
Diagnosis process terminates, now T=t+ Δs.Wherein, Δ is the time window length of probation or pre- according to actual conditions
If constant.
