Detailed Description
In order to make the technical solutions in the present specification better understood by those skilled in the art, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only some embodiments of the present specification, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
In the related art, training for the LLM model may generally include two training phases, pre-training and fine-tuning training.
The pre-training is a training method for performing unsupervised training on a language model through a large number of unlabeled language texts, so that the model has a plurality of general language processing capacities.
For example, the mainstream pre-training scheme adopted by the LLM model is a training method called Mask mechanism. By adopting a Mask mechanism, part of vocabularies in the unmarked language text can be masked in advance, and the ability of the model to predict the masked vocabularies is further trained on the basis.
The fine tuning training is a training method in which parameters of a model are adjusted based on a data set in a specific application scene on the basis of pre-training, for example, a part or all of the parameters of the model can be adjusted and updated, or the existing parameters of the model can be frozen, and the parameters are newly added on the basis of the frozen parameters, so that the model after fine tuning training can be applied to the application scene, and the model capability corresponding to the application scene is provided.
For example, taking an application scenario of intelligent question and answer as an example, in practical application, on the basis of a model which is pre-trained by adopting the Mask mechanism, fine tuning training can be further performed on the model based on a pre-constructed data sample related to the intelligent question and answer, so that the pre-trained model is further adjusted to be an application scenario which can be suitable for the intelligent question and answer, and a model of multi-round dialogue of a required answer can be generated for a user by performing common sense reasoning based on a problem input by the user.
Along with the continuous progress of technology, application scenes derived based on the LLM model are more and more abundant, so how to utilize the derived application scenes to provide better service for users is a problem that the application scenes in the field of the LLM model are explored.
In view of this, a user service mode is proposed in this specification that combines the LLM model with the intelligent service terminal in depth.
In the service mode, on one hand, fine-tuning training for the LLM basic model based on user service data corresponding to the service scene can be provided on the intelligent service terminal to obtain at least one LLM service model, so that a user can select a proper LLM service model from the at least one LLM service model based on the self requirement, and the user can be provided with the service required by the user, and the flexibility of using the LLM model can be improved. Moreover, when the user needs to migrate to a new intelligent service terminal, only the LLM service model is needed to be selected from the at least one LLM service model again, the LLM service model can be continuously used for providing services for the user, and therefore migration cost of the user can be reduced.
On the other hand, by collecting the personalized service data set of the user generated in the process that the LLM service model selected by the user provides service for the user and further carrying out fine tuning training on the LLM service model based on the collected user service data set, the personalized LLM service model corresponding to the user can be obtained, thereby realizing the deep service customization of the intelligent service terminal of the user, and enabling the intelligent service terminal of the user to provide personalized user service for the user based on the LLM service model.
Referring to fig. 1, fig. 1 is a flowchart of a user service method based on LLM model shown in the present specification, wherein the intelligent service has at least one LLM service model; the LLM service model is obtained by performing fine adjustment training on a LLM basic model based on user service data corresponding to a service scene; the method comprises the following implementation processes:
step 102: acquiring a target LLM service model corresponding to a target service scene designated by a user from the at least one LLM service model;
The intelligent service terminal of the user can comprise intelligent equipment for providing service for the user in the form of tasks.
For example, in one example, the smart device may be a smart robot, and the user may customize the service of the smart robot for the user service provided by the user by deploying a required service scenario corresponding to the LLM service model on the smart robot.
Of course, in practical application, the intelligent device may be other intelligent devices besides the intelligent robot.
For example, the smart devices may be classified based on the types of services that they may provide to users, and may also include electronic households, electronic pets, smart coaches, etc., which are not listed in this specification. In one embodiment, please refer to fig. 2, fig. 2 is a schematic diagram of a service framework for providing services to users based on LLM model shown in the present specification.
As shown in fig. 2, in practical application, an intelligent service terminal of a user may access a service platform as a background. Wherein, on the service platform, a LLM basic model can be pre-trained in a pre-training mode based on user data maintained on the platform.
In one embodiment shown, the LLM base model may be a multimodal LLM model. That is, the LLM base model may be a LLM model that can process a plurality of different types of data such as images, sounds, videos, etc. simultaneously, in addition to text.
For example, in practical application, in the process of training the LLM base model in a pre-training manner based on user data maintained on the platform, the service platform may introduce a plurality of different types of data such as images, sounds, videos, etc. as training samples based on the training samples in text form to train the LLM base model, so that the LLM base model has multi-modal data processing capability.
In addition, the user data maintained on the service platform may further include user service data corresponding to at least one preset service scenario. The service platform may further perform fine-tuning training on the LLM base model based on the user service data corresponding to the at least one service scenario on the basis of the LLM base model, to obtain at least one LLM service model. The at least one LLM service model may correspond to different service scenarios, and have different service capabilities.
For example, in one example, the at least one LLM service model may specifically include a first LLM service model with learning coaching capability, a second LLM service model with medical capability, a third LLM service model with communication session capability, and so on, which are not listed in the present specification.
The service platform may be a centralized service platform or a decentralized service platform, and is not particularly limited in this specification.
For example, in one embodiment, the service platform may be a decentralized cloud service platform, and the LLM base model and the LLM service model may be LLM cloud service models that are obtained by training with computing power of a service cluster in the cloud service platform based on cloud service data maintained on the cloud service platform. Of course, in practical application, the service platform may be a centralized service platform, and is not particularly limited in this specification.
At least one LLM service model obtained by performing fine tuning training on the LLM basic model on the service platform can be opened to a user, so that the user can select a target LLM service model corresponding to a target service scene required by the user from the at least one LLM service model based on specific requirements. And the intelligent service terminal of the user can respond to the selection operation of the user to acquire a target LLM service model corresponding to the target service scene designated by the user from the at least one LLM service model, and then deploy the acquired target LLM service model locally.
In one embodiment shown, with continued reference to fig. 2, the service platform may provide a service download interface to the user and open at least one LLM service model from the fine-tuning training to the user via the service download interface. And the user can perform downloading operation in the service downloading interface based on the self requirement to specify a required target service scene and trigger downloading of a target LLM service model corresponding to the target service scene.
The intelligent service terminal can determine a target service scene designated by the user in response to the downloading operation of the LLM service model triggered by the user in the service downloading interface, and send a downloading request containing a scene identifier corresponding to the target service scene to the service platform. After receiving the download request, the service platform can acquire a scene identifier contained in the download request, determine a target LLM service model corresponding to a target service scene indicated by the scene identifier from at least one provided LLM service model, and return a download result of the target LLM service model to the intelligent service terminal. After the intelligent service terminal acquires the target LLM service model, the intelligent service terminal can locally deploy the target LLM service model.
It should be noted that, in practical application, the computing power resource that the intelligent service terminal can provide may be far lower than that of the service platform, so if the user selects to download the target LLM service model to the intelligent service terminal for running, the situation may occur that the resource amount of the computing power resource of the intelligent service terminal is insufficient for normal running of the target LLM service model.
In the illustrated embodiment, if the user selects to download the target LLM service model to the intelligent service terminal for running, in order to ensure that the computing power resources allocated to the target LLM service model on the intelligent service terminal are enough to run the target LLM service model, after the intelligent service terminal obtains the target LLM service model, the intelligent service terminal may further determine the resource amount of the computing power resources allocated to the target LLM service model by the intelligent service terminal, and then at least refer to the resource amount to perform model compression on the target LLM service model, so that the compressed target LLM service model can run normally on the intelligent service terminal, and then deploy the compressed target LLM service model on the intelligent service terminal.
It should be noted that, performing model compression on the LLM model generally refers to reducing the scale of parameters of the model on the premise of maintaining the performance of the LLM model, so as to enable deployment and operation of the LLM model in a resource-constrained environment. In practical application, a specific method for compressing the LLM model to reduce the scale of the parameters of the model can be flexibly adjusted and selected according to specific requirements and the scale of the computing power resource of the intelligent service terminal, and is not particularly limited in the present specification.
For example, common methods for reducing the size of parameters of the model may include such methods as sparsifying parameters of the LLM model, pruning parameters of the LLM model, quantifying parameters of the LLM model, and the like, which may be used alone or in combination in practical applications.
It should be explained that, the sparse processing of the parameters of the LLM model generally means that some parameters with low contribution to the model in the LLM model are set to zero or close to zero, so as to achieve the purpose of reducing the number of parameters. This can reduce the parameter scale of the model to some extent while preserving the performance of the model on a particular task.
Pruning the parameters of the LLM model generally refers to removing some parameters of the LLM model that have a low degree of contribution to the model, thereby reducing the parameter size.
Parameter quantization of parameters of the LLM model generally refers to converting parameters in the LLM model from floating point numbers to lower bit width integers or fixed point numbers to reduce the storage requirements of the model. For example, FP8 (Fixed-Point 8-bit) quantization is a commonly used method of parameter quantization, and the FP8 quantization is used to transform parameters from a floating-Point representation to a Fixed-Point representation.
It should be noted that, in both the sparsification process and pruning process of the parameters of the LLM model, the parameters having low contribution to the model need to be carefully selected to ensure that the influence on the performance of the model is as small as possible. In practical application, a proper method can be selected based on practical requirements, contribution degree of parameters in the LLM model to the LLM model is calculated, then parameters with smaller influence on the LLM model are screened out according to a calculation result, and then thinning or pruning treatment is carried out on the parameters. The specific process of calculating the contribution degree of the parameters in the LLM model to the LLM model is not described in detail in the present specification.
Of course, in practical application, the target LLM service model selected by the user from the at least one LLM service model may be specifically and remotely deployed on the service platform only, without being downloaded to the intelligent service terminal of the user. In this case, after the user designates the target service scenario on the intelligent service terminal, the intelligent service terminal may provide the corresponding service to the user by remotely calling the target LLM service model corresponding to the target service scenario deployed on the service platform. Step 104: responding to a service request of a user, operating the target LLM service model to provide user service corresponding to the target service scene for the user, and collecting a user service data set generated in the process of providing the user service for the user; wherein the user service data set comprises service data generated in the process of providing the user service for the user and service feedback data of the user for the user service;
After the user selects a target LLM service model corresponding to a target service scenario designated by the user from the at least one LLM service model, the intelligent service terminal may operate the target LLM service model in response to a service request of the user to provide the user with a user service corresponding to the target service scenario.
In the illustrated embodiment, referring to fig. 2, if a user selects to download a target LLM service model corresponding to a target service scenario designated by the user from the at least one LLM service model to a local location of an intelligent service terminal for operation, the intelligent service terminal may execute the target LLM service model in response to a service request of the user after deploying the target LLM service model to the local location, and provide a user service corresponding to the target service scenario to the user.
For example, taking the target LLM service model as a question-answer model with interactive dialogue capability as an example, the service request may specifically be a question text which is input by the user and can embody the needs or intentions of the user, and after receiving the question text, the target LLM service model may perform general knowledge reasoning based on the question input by the user, generate and output an answer for the user, which can solve the question of the user, and develop the dialogue with the user.
With continued reference to fig. 2, in the process of running the target LLM service model to provide the user with the user service corresponding to the target service scenario, some personalized user service data is usually generated. The intelligent service terminal can also collect the generated user service data to form a user service data set, and the collected user service data set can be used for further fine tuning training on the target LLM service model.
Wherein the personalized user service data generated by running the target LLM service model may generally include service data generated in the process of providing user services to users.
For example, taking the target LLM service model as a question-answer model with interactive dialogue capability as an example, the service data may be answer text generated for the user based on the questions input by the user during the process of developing dialogue between the target LLM service model and the user. In addition, the personalized user service data may further include service feedback data of the user for the user service provided by the target LLM service model.
It should be noted that, the user service data (including, but not limited to, user equipment information, user personal information, data for analysis, stored data, presented data, etc.) in the above embodiments are information and data authorized by the user or sufficiently authorized by each party, and the collection, use and processing of the data are required to comply with relevant laws and regulations and standards of relevant countries and regions, and are provided with corresponding operation entries for the user to select authorization or rejection.
In one embodiment shown, the intelligent service terminal may provide an interactive mechanism for the user to conduct service feedback for the user's service. When collecting service feedback data, the intelligent service terminal can specifically output a service feedback prompt for the user service to the user based on the interaction mechanism, and acquire service feedback data further submitted by the user according to the service feedback prompt.
For example, in one example, the interaction mechanism of the user service feedback may be a mechanism for interaction with the user through voice. When collecting service feedback data, the intelligent service terminal can specifically output a service feedback prompt in a voice form to the user, and acquire the service feedback data in the voice form which is further submitted by the user according to the service feedback prompt.
Step 106: and performing fine tuning training on the target LLM service model based on the user service data set to obtain a personalized LLM service model corresponding to the user, and continuously providing user service corresponding to the target service scene for the user based on the personalized LLM service model.
With continued reference to fig. 2, after collecting the user service data generated by running the target LLM service model to form a user service data set, the intelligent service terminal may further perform fine-tuning training on the target LLM service model based on the collected user service data set.
It should be noted that, since the user service data generated by running the target LLM service model on the intelligent service terminal is generally personalized service data of some users, after performing fine-tuning training on the target LLM service model based on the user service data set, a personalized LLM service model corresponding to the users can be obtained.
In one embodiment, please refer to fig. 3, fig. 3 is a schematic diagram illustrating two-stage fine-tuning training of LLM service models according to the present disclosure.
As shown in fig. 3, the two-stage fine tuning training may specifically include a process of performing a first-stage fine tuning training on the LLM basic service model on the service platform to obtain the target LLM service model, and a process of performing a second-stage fine tuning training on the target LLM service model locally at the intelligent service terminal based on the collected user service data set to obtain the personalized LLM service model corresponding to the user. In this case, after the intelligent service terminal collects the user service data set, the intelligent service terminal may further perform fine-tuning training on the deployed target LLM service model locally on the intelligent service terminal, so as to obtain a personalized LLM service model corresponding to the user.
For example, in one example, a TEE (Trusted execution environment ) running environment may be built in the local running environment of the intelligent service terminal, and in the TEE running environment, fine-tuning training is performed on the target LLM service model based on the collected user service data set.
It should be noted that, because the user service data generated by the intelligent service terminal running the target LLM service model locally is usually some data related to user privacy, the second-level fine tuning training is completed locally at the intelligent service terminal, so that the problem of user privacy data leakage caused by that the user service data is led out of the intelligent service terminal can be avoided.
Of course, in practical application, if the data size of the user service data set collected by the intelligent service terminal is larger, the second-stage fine-tuning training shown in fig. 3 may specifically be performed by migrating to the service platform in a form of security privacy calculation.
In another embodiment, the intelligent service terminal may perform security privacy calculation on the collected user service data set to obtain a ciphertext data set corresponding to the user service data set, and then upload the ciphertext data set to the service platform, where the service platform further performs fine tuning training on the target LLM service model based on the ciphertext data set on the premise of not revealing the privacy data of the user.
The type of the algorithm for the security privacy calculation used by the intelligent service terminal is not particularly limited in the present specification.
For example, in one example, the security privacy calculation may specifically be a homomorphic encryption algorithm. Based on homomorphic encryption algorithm, the data can be homomorphic encrypted and then calculated in the form of ciphertext, and the calculation result obtained after corresponding homomorphic decryption of the obtained ciphertext calculation result is equivalent to the calculation result obtained by directly carrying out the same calculation on the original plaintext data, so that the data can be "invisible". The intelligent service terminal can perform homomorphic encryption calculation on the user service data set to obtain a ciphertext data set corresponding to the user service data set, the ciphertext data set is uploaded to the service platform, and the service platform performs fine tuning training calculation on the target LLM service model based on the ciphertext data set. After finishing the fine-tuning training calculation for the target LLM service model based on the ciphertext data set, the service platform can homomorphically decrypt the calculation result, and then adjust and update the model parameters of the target LLM service model based on the decrypted calculation result so as to finish the fine-tuning training for the target LLM service model.
The process of homomorphic encryption and decryption calculation for the user service data set and adjustment and update for the model parameters of the target LLM service model is not described in detail in the present specification, and those skilled in the art may refer to the description in the related art when the technical solution disclosed in the present specification is put into practice.
Whether the target LLM service model is subjected to fine tuning training based on the user service data set locally at the intelligent service terminal or the user service data set is uploaded to the service platform, the service platform adopts a secure privacy calculation mode to perform fine tuning training on the target LLM service model based on the user service data set, and the specific training method is not particularly limited in the specification.
In one embodiment shown, the targeted LLM service model described above may be fine-tuned using a supervised training approach. In this case, when performing fine tuning training on the target LLM service model based on the user service data set, a data tag may be constructed based on service feedback data included in the user service data set, then data marking is performed on service data included in the user service data set based on the constructed data tag, and then the service data with the data marked is used as a training sample, and the supervised fine tuning training is performed on the target LLM service model.
The specific process of performing the supervised fine tuning training on the target LLM service model based on the user service data set is not described in detail in the present specification, and a person skilled in the art may refer to the description in the related art when the technical solution disclosed in the present specification is put into practice.
In another embodiment shown, the target LLM service model may also be fine-tuned by a training method of reinforcement learning. In this case, when performing the fine-tuning training on the target LLM service model based on the user service data set, the fine-tuning training based on the reinforcement learning may be performed on the target LLM service model with the service data included in the user service data set as the reinforcement learning operation and the service feedback data included in the user service data set as the reinforcement learning state.
The specific process of performing reinforcement learning-based fine-tuning training on the target LLM service model based on the user service data set is not described in detail in the present specification, and a person skilled in the art may refer to the description in the related art when the technical solution disclosed in the present specification is put into practice.
In the present specification, after fine tuning training is further performed on the target LLM service model based on the user service data set to obtain a personalized LLM service model corresponding to the user, the intelligent service terminal may continue to provide, for the user, user services corresponding to the target service scenario based on the personalized LLM service model, and continue to collect service data generated in the process of running the personalized LLM service model in the process of providing services, and then continue to perform fine tuning training on the LLM service model based on the service data, so that the target LLM service model locally deployed at the intelligent service terminal may be optimized continuously, and more personalized user services may be provided for the user.
In the above technical solution, on one hand, by deploying the pre-trained LLM base model on the service platform and performing fine-tuning training on the LLM base model based on the user service data corresponding to at least one service scene to obtain at least one LLM service model, a user can select a suitable LLM service model from the at least one LLM service model based on the needs of the user, and deploy the LLM model to the intelligent service terminal, services required by the user can be provided for the user, so that the flexibility of using the LLM model can be improved. Moreover, when the user needs to migrate to a new intelligent service terminal, the user only needs to select the LLM service model from the at least one LLM service model again and deploy the LLM service model to the new intelligent service terminal, so that the migration cost of the user can be reduced.
On the other hand, by collecting the personalized service data set of the user generated in the process that the LLM model deployed on the intelligent service terminal of the user provides services for the user and further carrying out fine adjustment training on the LLM model based on the collected user service data set, the personalized LLM service model corresponding to the user can be obtained, thereby realizing deep service customization of the intelligent service terminal of the user, and enabling the intelligent service terminal of the user to provide personalized user services for the user based on the deployed LLM service model.

In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable GATE ARRAY, FPGA)) is an integrated circuit whose logic functions are determined by user programming of the device. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented with "logic compiler (logic compiler)" software, which is similar to the software compiler used in program development and writing, and the original code before being compiled is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but HDL is not just one, but a plurality of kinds, such as ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language), and VHDL (Very-High-SPEED INTEGRATED Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application SPECIFIC INTEGRATED Circuits (ASICs), programmable logic controllers, and embedded microcontrollers, examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C2051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.
