Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
The present embodiment provides a method for recommending medicated diet, and referring to fig. 1, the method for recommending medicated diet of the present embodiment includes:
s101, acquiring a disease name and a disease expression of a user.
In this embodiment, the disease name (e.g., respiratory diseases such as rhinitis, pharyngitis, laryngitis, tracheitis, bronchitis, asthma, pneumonia, etc.) and the disease expression (e.g., wheezing, shortness of breath, cough, nasal obstruction, hoarseness, etc.) of the user may be obtained based on the voice of the user, and specifically, first, the voice signal of the user may be collected, for example, the voice signal of the disease expression may be collected by the user, and then the voice print recognition may be performed on the voice signal to recognize the disease name of the user, and the semantic recognition may be performed on the voice signal to recognize the disease expression of the user voice input.
The voiceprint recognition is mainly based on a voiceprint acoustic detection technology, acoustic characteristic parameters are extracted to construct a voiceprint recognition model, so that standard voice (healthy voice) and pathological voice can be recognized, and disease names corresponding to the pathological voice can be recognized. Specifically, the identification of the disease name by using voiceprint recognition mainly comprises two aspects of establishment of a voiceprint recognition model and voiceprint recognition, and the establishment of the voiceprint recognition model mainly comprises two parts of collection of a voice sample and extraction of characteristic parameters of the sample.
Specifically, the sound sample collection may include standard (standard voice) sample collection and abnormal (sick voice) sample collection, and the collected sound sample set may be recorded as S i Where i is used to indicate the type of sound sample, e.g. S when i =0 i Can characterize a standard sample set corresponding to the standard voice, and the number of samples can be recorded as N 0 When i ≠ 0, S i An abnormal sample set corresponding to the pathological voice can be characterized, and each disease type is assumed to comprise g types, namely, the name of each disease can be recorded as: s 1 ,S 2 ,…,S g The number of samples corresponding to each type of disease can be recorded as N i (i =1,2, ..., g). Thus, each sound sample set S i Can be recorded as S i (s i1 ,…,s ij ,…,s iNi ) Wherein s is ij J sample, N, representing the ith sample set i The number of samples in the ith type sample set is shown.
For extracting sample characteristic parameters, wherein the parameter index for establishing the voiceprint recognition model can cover but is not limited to acoustic information such as tone quality, volume, tone, pronunciation duration, range, special sound type (such as cough) and the like, the sample s ij Can be denoted as s ij ＝(x 0 ,…,x k ,…,x n ) Wherein x is k Representing a sample s ij N characterizes the number of the characteristic parameters.
The voiceprint recognition may include collecting a voice signal of the user, extracting a characteristic parameter of the voice signal, and recognizing a voiceprint of the user, where the collected voice signal may be recorded as an object s to be measured, and the extracted characteristic parameter of the object s to be measured may be recorded as s = (x =)' 0 ,…,x′ k ,…,x′ n ). The step of recognizing the voiceprint of the user specifically comprises inputting the characteristic parameters of the target s to be detected into the voiceprint recognitionThe model is identified and matched, for example, based on the improved Hausdorff distance (LTS-HD, denoted as D) LTS ) The K-nearest neighbor algorithm of (1) is used as a classification basis, and specifically, the distance D between the target s to be detected and all the sound samples in the g +1 class sound sample set is calculated firstly LTS (s,s ij ) And then the resulting D will be calculated LTS (s,s ij ) The sound samples are sorted in an increasing mode according to results, the first K minimum distances are taken as K neighbor, and then the K neighbor obtained through statistics belongs to the sound sample set S i Frequency of (t) i (i =0,1, ..., g), finally defining p = index (max { t) } 0 ,…,t g }), where index represents the index acquisition function, i.e. the index for which p is the maximum frequency, S ∈ S p Obtaining a sound sample set to which the sample to be detected belongs, wherein if p =0, S is output 0 The voice analysis result of the user is represented as healthy, and if p is not equal to 0, S is output p And characterizing the corresponding disease name of the user.
S102, food materials and medicinal materials favorable for disease names are searched for, so that a benign food material set and a benign medicinal material set are respectively constructed.
Specifically, step S102 may include the step of acquiring a first map and the step of acquiring a second map. The first map may include a disease name, a food material, and a first attribute value, wherein the food material is a food material favorable for the disease name, the first attribute value is used for representing a degree of interest of the food material for the disease name, for example, the first attribute value may be represented as r ingre May have r ingre = {1,5}, in which, r ingre =1 the degree of benefit of the food material to the disease name is appropriate, r ingre =5 can represent the degree of interest of food materials in the disease name as strongly appropriate. The second map may include a disease name, a herb, and a second attribute value, wherein the herb is favorable for the disease name, the second attribute value is used to represent the degree of benefit of the herb for the disease name, for example, the second attribute value may be denoted as r med May have r med =1, 3,5, wherein r med =1 the beneficial degree of the herb to disease name is weak suitable, r med =3 the degree of benefit of the herb to disease name is moderate, r med =5 characterizableThe medicinal materials have strong and proper beneficial degree on disease names. It should be understood that the first attribute value and the second attribute value may be set by a user according to an actual application, and are not limited to the above value example.
In this embodiment, the benign food material set can be denoted as F good ＝{f 1 ,…,f j ,…,f q In which f j = [ food material, r) ingre ]The obtained benign herb collection can be recorded as M good ＝{m 1 ,…,m i ,…,m p In which m is i = [ medicinal materials, r) med ]。
S103, food materials and medicinal materials which are beneficial to disease manifestation are searched, so that the benign food material set and the benign medicinal material set are updated respectively.
Specifically, step S103 may include a step of acquiring a third map and a step of acquiring a fourth map. The third map may include a disease manifestation, a food material, and a third attribute value, wherein the food material is a food material favorable for the disease manifestation, and the third attribute value is used for representing a degree of benefit of the food material on the disease manifestation, for example, the third attribute value may be denoted as sym ingre May have sym ingre =1, 5, wherein sym ingre =1 the beneficial degree of food material to disease manifestation is appropriate, sym ingre =5 can characterize the favorable degree of food material for the manifestation of the disorder as strongly appropriate. The fourth map may include disease manifestation, medicinal materials, and a fourth attribute value, wherein the medicinal materials are medicinal materials beneficial to disease manifestation, the fourth attribute value is used for representing the degree of benefit of the medicinal materials on disease manifestation, for example, the fourth attribute value may be denoted as sym med There may be sym med =1,3,5, wherein sym med =1 the beneficial degree of the herb to the manifestation of the disease is weakly appropriate, sym med =3 the beneficial degree of the medicinal material to the disease manifestation is moderate and appropriate, sym med =5 the medicinal material has strong and appropriate degree of favorable degree for the manifestation of the disease. It should be understood that the third attribute value and the fourth attribute value may be set by self according to the actual application, and are not limited to the above value example.
