Description

Technical Field

[0001] This invention relates to the field of artificial intelligence technology, and more specifically, to a federated fine-tuning large model evaluation report generation system, method, and storage medium. Background Technology

[0002] With the rapid development of the knowledge economy, the quantity and complexity of intellectual property rights are growing exponentially. This has made traditional manual review and evaluation methods increasingly inadequate to meet practical needs, driving the rapid development of intelligent evaluation technologies. In recent years, large language models (LLMs) based on artificial intelligence technology have been increasingly widely used in the patent and intellectual property fields. They possess powerful semantic understanding and generation capabilities, and can, to some extent, replace manual tasks such as intellectual property document retrieval, text classification, and intelligent evaluation. This technology typically relies on deep learning and pre-trained models, trained in a self-supervised manner using large-scale text corpora, thus possessing strong generalization and understanding capabilities.

[0003] However, while existing large-scale language models excel in semantic understanding and generation tasks, they still have significant shortcomings in intellectual property assessment applications. First, the intellectual property field involves complex and diverse data sources, including legal provisions, technical cases, judicial precedents, full-text patents, images, and tables—multimodal information. Existing models primarily focus on text-based single-modal processing, making it difficult to efficiently integrate and analyze multi-source heterogeneous data, resulting in a one-sided and insufficient assessment process. Second, the laws, regulations, and market environment in the intellectual property field change frequently. Existing semantic understanding models often rely on static knowledge graphs as background support, lacking dynamic real-time update capabilities and failing to quickly respond to regulatory changes and market dynamics. This lag reduces the timeliness and reliability of assessment conclusions and may lead to the risk of misjudgment.

[0004] To address these issues, some studies have attempted to achieve cross-institutional data collaboration through federated learning techniques and protect data privacy with secure aggregation protocols, achieving initial attempts at joint training of multi-party models. However, they have not yet effectively integrated cross-modal data, and most lack sufficient attention to model interpretability and evaluation credibility. Furthermore, regarding model fine-tuning, current conventional methods for fine-tuning large language models involve a large number of parameters and high computational costs, making them difficult for resource-constrained enterprises to deploy effectively and to meet the need for rapid updates at the minute level. Simultaneously, the traceability and immutability of model updates during fine-tuning lack effective guarantees, failing to meet the practical application requirements of high credibility and regulatory oversight in intellectual property assessment.

[0005] Recent research has shown that Generative Adversarial Networks (GANs) and gradient attribution techniques are gaining increasing attention for improving the credibility and interpretability of model outputs. These methods analyze the relationship between model outputs and inputs through gradient attribution analysis, or construct adversarial examples to test model stability. However, current technologies typically apply these methods independently, lacking organic integration, and have not yet formed a systematic solution for intellectual property assessment scenarios. Furthermore, existing solutions lack timely and effective automatic correction mechanisms to address insufficient model evaluation credibility, making it difficult to ensure the long-term stability and reliability of the evaluation model's output.

[0006] Therefore, how to provide a system, method, and storage medium for generating evaluation reports for federally tuned large models is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

The interpretability and robustness verification unit is used to generate cross-modal significance heatmaps and causal chain descriptions based on dual gradient attribution for each evaluation conclusion, and to perform adversarial sample robustness tests using generative adversarial networks.

[0032] like Figure 2 As shown, the present invention also provides a method for generating an evaluation report, the method comprising: Step S1: Collect cross-domain legal events and update the intellectual property semantic graph to complete causal reasoning and confidence labeling; Step S2: Multimodal encoding of text, images, tables and full-text patents is performed locally on each data holder's site, and federated training is completed through secure aggregation. Step S3: Generate a structured evaluation report and a verifiable chain of evidence based on the cross-modal alignment matrix; Step S4: Utilize four-dimensional feedback to drive multi-agent reinforcement learning, and synchronize expert routes, adapter parameters, and semantic graph confidence intervals within minutes. Step S5: Perform LoRA-IA3 fine-tuning with parameters not exceeding one percent of the original model, and write the hash and zero-knowledge proof into the blockchain. Step S6: Perform dual gradient interpretability analysis and adversarial robustness verification on the evaluation results, and automatically roll back the model version if necessary.

Then, the semantic graph is updated through an incremental graph convolution-differential update algorithm. The graph node embedding dimension is 128 dimensions. A multi-hop graph attention mechanism with 3 attention heads is used to calculate the causal score and label the confidence level. Second, BERT, ResNet-50, and TabNet are used to encode text, image, and tabular data respectively, and a feature embedding vector with a dimension of 256 is uniformly generated. Multimodal data federated learning is completed through a gated expert hybrid (MoE) model containing 4 expert sub-networks and the FedAvg secure aggregation protocol. Cosine similarity is used to calculate the cross-modal dynamic alignment matrix. Based on this matrix, a structured assessment report containing a verifiable evidence chain with supporting sample SHA256 hashes is generated in parallel. Third, a four-dimensional assessment report is constructed based on legal, technical, market, and competitive landscape data. The feedback vector, composed of multiple dimensions, utilizes the PPO algorithm for multi-agent reinforcement learning with a learning rate set to 0.0003. Policy updates are performed every minute, with route update step sizes set to 0.01 and adapter update step sizes set to 0.005. Expert route weights and adapter parameters are adjusted in real-time, and the semantic graph confidence interval is dynamically adjusted. Update logs are written to the blockchain ledger every minute. Then, efficient fine-tuning is performed using a LoRA-IA3 adapter with an explicitly defined rank of 8, with a limit not exceeding 1% of the original model's total parameters. Meta-learning initialization parameters are obtained through... The MAML algorithm is used to obtain the SHA256 hash value of the fine-tuned parameters, which is then processed by the Groth16 zero-knowledge proof protocol and recorded to the blockchain every minute. Finally, for each evaluation conclusion, a significance heatmap is generated using the dual gradient attribution method, with a significance threshold set to 0.7. The generative adversarial network uses the FGSM method with a perturbation amplitude of 0.01 to generate adversarial examples and calculates the robustness score. When the confidence level is lower than 0.85 or the robustness is lower than 0.95, it automatically rolls back to the previous trusted version, and the rollback parameter hash is recorded to the blockchain every minute. This invention also discloses a computer-readable storage medium, specifically a 128GB solid-state drive, in which a computer program implementing the above method is stored. The program is explicitly written in Python and can be executed in a Linux system environment equipped with an Intel Xeon processor and 64GB of memory.

[0038] Example 1 To verify the feasibility of this invention, the interpretable federated fine-tuning large-scale model intellectual property assessment and credible report generation system of this invention was applied to an undergraduate university in Wuhu City, Anhui Province (hereinafter referred to as University C). As a key local university, University C has achieved significant research results in recent years in fields such as intelligent manufacturing, new energy vehicles, and electronic information, with approximately 1200 patent applications annually. However, with the increase in the number of patent applications, the university's intellectual property management department faces prominent problems such as poor assessment timeliness, scattered and difficult data integration, slow model parameter adjustment, and a lack of credibility assurance in assessment results. Traditional manual assessment methods can no longer meet the rapidly growing patent assessment needs of universities. To effectively solve the above problems, University C decided to deploy the system of this invention to improve the efficiency of intellectual property assessment and management and enhance the quality of technology transfer.

[0039] The system of this invention was deployed in the Information Center of University C, located in Jinghu District, Wuhu City, Anhui Province. This center is equipped with a high-performance server cluster, including computing nodes with Intel Xeon processors, 256GB of memory, and Tesla V100 GPUs, meeting the system's requirements for real-time data processing and complex computational tasks. The system first employs a distributed crawler task queue, polling every 2 minutes to retrieve announcements from the State Intellectual Property Office, the Supreme People's Court's case law database, and technical news from CNKI, VIP, and major global technology media websites. It collects patent law changes and technological developments in real time, and after cleaning and processing, forms structured node data. Each data update takes only about 85 seconds to inject the node data into the intellectual property semantic graph. The graph update uses the incremental graph convolution-difference algorithm of this invention, with a node embedding dimension of 128. The graph attention mechanism uses three attention heads to achieve efficient causal reasoning and dynamic confidence labeling of "article-terminology-case-judgment-market indicators".

[0040] University C comprises multiple colleges and research teams, each possessing abundant but scattered research data, including research papers, patent texts, engineering drawings, design images, and experimental data tables. This data is stored in a dispersed manner and exhibits significant cross-modal characteristics, making traditional aggregation and analysis methods inefficient and posing high data security risks. This invention addresses this issue by establishing federated learning nodes in the School of Mechanical Engineering, the School of Electrical Engineering, and the School of Information Science and Technology through a federated multimodal evaluation-generation unit. Employing a gated expert hybrid (MoE) model, text data is uniformly encoded into 256-dimensional feature vectors using a BERT model, image data using a ResNet-50 model, and tabular data using a TabNet model. A federated averaging algorithm (FedAvg) is then used for secure aggregation via homomorphic encryption, and the data is jointly trained at the central node. This enables secure analysis and fusion of cross-departmental data without leaving the campus. During a three-month trial run, the system has securely processed approximately 3,600 cross-modal data items and generated over 1,200 intellectual property assessment reports.

[0041] Furthermore, to address the issues of slow parameter adjustment and inability to quickly adapt to dynamic changes in scientific research using traditional evaluation models, this invention deploys an adaptive model and knowledge synchronization unit. It employs the PPO algorithm based on multi-agent reinforcement learning, using feedback signals from legal, technological, market, and competitive landscape aspects as input to dynamically adjust expert routing weights, adapter parameters, and the confidence interval of the semantic graph. The model parameters are automatically updated and adjusted every minute. Implementation results show that this invention reduces the parameter adjustment delay from several hours using manual methods to an average of less than 40 seconds, effectively improving the model's real-time response capability.

[0042] Meanwhile, to achieve rapid and efficient domain-specific model fine-tuning, the parameter-efficient fine-tuning unit of this invention, after being deployed in the information center of University C, uses a LoRA-IA3 adapter with a explicitly set rank of 8 for efficient parameter fine-tuning. The parameter update amount is strictly controlled within 1% of the total number of parameters in the original model, and the meta-learning initialization uses the MAML algorithm. On-site data shows that the average single fine-tuning process has been reduced from 120 minutes to 12 minutes, and resource consumption has been reduced by approximately 90% compared to traditional fine-tuning methods. In addition, by recording parameter hash values ​​using zero-knowledge proofs and a blockchain ledger, once per minute, strict supervision and high trust in the model fine-tuning process are achieved.

[0043] Furthermore, to enhance the reliability and credibility of the model evaluation conclusions, this invention deploys an interpretability and robustness verification unit. Based on the dual gradient attribution method, the threshold for generating saliency heatmaps and identifying salient regions for each evaluation conclusion is set to 0.7. Adversarial samples with a perturbation amplitude of 0.01 are generated using the Fast Gradient Sign Method (FGSM) in Generative Adversarial Networks (GANs) to evaluate the model's robustness. Once an evaluation conclusion's confidence level is detected to be below 0.85 or its robustness below 0.95, it is automatically rolled back to the previous credible version, and the rollback hash is recorded in the blockchain ledger every minute. During implementation, a total of 16 rollback operations were triggered, ensuring the high credibility and stability of the evaluation conclusions.

[0044] Table 3 shows the significant improvement in the intellectual property evaluation system of University C three months after implementing the system of this invention: Table 1. Comparison of Intellectual Property Assessment Results Before and After Implementation at University C As shown in Table 1 above, after deploying the system of this invention, the intellectual property assessment process of University C has been significantly improved: the assessment time for a single patent has been reduced from 5 hours to 18 minutes, and the number of patent reports generated per month has increased dramatically from 100 to 400; the response time to regulatory changes has been shortened from 48 hours to 85 seconds; the model fine-tuning time has been reduced from approximately 120 minutes to 12 minutes, saving approximately 90% of computing resources; the accuracy of multimodal data analysis has increased from 80% to 95%; a total of 16 timely rollback operations were triggered during the deployment period, ensuring that the model results were highly reliable and that no data security incidents occurred. Furthermore, the response delay for model parameter adjustments has been significantly shortened from several hours to several days to an average of 40 seconds, greatly improving the overall assessment efficiency and reliability assurance capabilities of the intellectual property management department of University C.

[0045] As seen in the above examples, the implementation of the system of the present invention at University C has not only effectively solved the problems of low evaluation efficiency, difficulty in multimodal data fusion, lag in parameter adjustment, and lack of credibility of the original manual evaluation method, but also significantly improved the timeliness, accuracy, data security and credibility of intellectual property evaluation. It has won unanimous recognition from the technical management department of the university, which proves the outstanding advantages and technological advancement of the present invention in practical applications.

[0046] Example 2 To verify the feasibility of this invention, the interpretable federated fine-tuning large-scale model intellectual property assessment and credible report generation system of this invention was applied to a medium-sized technology company (hereinafter referred to as Company D) located in Hefei City, Anhui Province. Company D is a technology enterprise specializing in artificial intelligence chips, Internet of Things devices, and new energy technologies, with an average annual patent application volume of approximately 800. Patent assessment has become a crucial link in the company's transformation of innovative achievements and protection of intellectual property rights. However, with the continuous expansion of the company's technological fields and the rapid growth of patent applications, the traditional manual assessment methods have become increasingly problematic due to their time-consuming nature, low efficiency, slow response to regulatory changes, and difficulty in ensuring data security. These issues severely restrict the company's rapid response to technological innovation and the accuracy of decision-making. To effectively solve the above problems, Company D decided to deploy the assessment system of this invention, aiming to improve the efficiency, reliability, and security of intellectual property management.

[0047] This invention's system is deployed in the R&D data center of Company D in Hefei High-tech Zone. The data center is equipped with a high-performance server cluster, including Intel Xeon Gold processors, 128GB of memory, and Tesla A100 GPU computing units, to meet the system's complex computing needs and large-scale data processing tasks. During system operation, a distributed crawler task queue is first used to crawl regulatory events, technological developments, and patent announcements from the official websites of global patent institutions such as the China National Intellectual Property Administration, the USPTO, and the European Patent Office (EPO), as well as judicial precedent databases and international science and technology media websites, every 2 minutes. This forms a real-time updated structured data of event nodes and edge relationships. After each data collection, the semantic graph is updated using an incremental graph convolution-differential update algorithm. The node embedding dimension is set to 128 dimensions, and a multi-hop graph attention mechanism with three attention heads is used for dynamic causal reasoning and confidence labeling of the "article-term-case-judgment-market indicator" five-tuple. The average time for each graph update is approximately 80 seconds, significantly improving the real-time update capability of the graph and ensuring Company D's timely response to global regulatory and technological changes.

[0048] Due to the numerous R&D departments within Company D, the multimodal data, including patent texts, drawings, images, and R&D data tables, are stored in a scattered manner, leading to information silos and data security risks in cross-departmental data fusion. To address this, this invention establishes federated learning nodes in the company's R&D, engineering, and intellectual property departments through a federated multimodal assessment-generation unit. It employs a gated expert hybrid (MoE) model, using BERT to encode text data, ResNet-50 to encode image data, and TabNet to encode tabular data, uniformly generating a 256-dimensional embedding vector. Through federated averaging (FedAvg) and homomorphic encryption, multimodal data can be securely fused without leaving the departments. Approximately 500 data points are analyzed daily, generating an average of over 40 assessment reports.

[0049] Furthermore, the adaptive model and knowledge synchronization unit of this invention adjust model parameters in real time based on feedback signals from laws, technology, markets, and competitive landscape, once per minute. Employing the PPO reinforcement learning algorithm, it dynamically updates expert routing weights, adapter parameters, and semantic graph confidence intervals. During actual operation, the average adaptive adjustment response time of the model parameters is only about 30 seconds, significantly better than the parameter update cycle of traditional models, which can take several hours or even longer, greatly improving the model's ability to respond to changes in real time.

[0050] Meanwhile, the high-efficiency parameter fine-tuning unit of this invention achieves rapid domain fine-tuning by adjusting parameters at a ratio not exceeding 1% of the original large language model, through a LoRA-IA3 adapter with an explicitly set rank of 8. The fine-tuning process is initialized using the MAML meta-learning algorithm, reducing the time consumed by each fine-tuning task from approximately 90 minutes to about 9 minutes, and reducing computational resource usage by about 90%. Through the Groth16 zero-knowledge proof protocol, the hash value of the fine-tuned parameters is recorded to the blockchain ledger every minute, ensuring the transparency and trustworthiness of parameter updates.

[0051] Furthermore, to ensure the credibility and robustness of the model's prediction results, the interpretability and robustness verification unit of this invention utilizes the dual gradient attribution method to generate a significance heatmap. With a significance threshold of 0.7, it clearly identifies key factors affecting the prediction results and generates adversarial examples using the Fast Gradient Sign Method (FGSM) in Generative Adversarial Networks (GANs) with a perturbation amplitude of 0.01 to test model robustness. When the model's output confidence score falls below 0.85 or its robustness score falls below 0.95, an automatic rollback to the previous trusted version is triggered, and the rollback parameter hash value is automatically recorded in the blockchain ledger. During the three-month deployment and operation period, a total of nine rollback events were triggered, promptly correcting abnormal model outputs and ensuring the reliability of the evaluation results.

[0052] Three months after deploying the system of this invention, Company D's intellectual property evaluation system showed significant improvement, as detailed in Table 4: Table 2 Comparison of Data on the Implementation Effects of Intellectual Property Assessment by Company D As clearly shown in Table 2 above, after implementing this invention, Company D's patent evaluation efficiency and quality have significantly improved. The average evaluation time for a single patent has decreased from 6 hours to 15 minutes, and the monthly number of patent evaluation reports generated has jumped from 80 to approximately 1200. The dynamic response capability to regulations has improved from approximately 24 hours to an average of 80 seconds. The time for a single model fine-tuning task has been shortened from 90 minutes to 9 minutes, saving approximately 90% of fine-tuning resources. The accuracy of multimodal data analysis has increased from 78% to 95.5%. Nine automatic rollbacks were triggered during implementation, effectively ensuring the high reliability of the evaluation results. No data security incidents occurred during implementation, significantly improving the company's intellectual property data security, and the real-time response capability for model parameter adjustments has also been significantly improved.

[0053] As can be seen from the above practical examples, the implementation of the evaluation system of the present invention effectively solves the practical problems of low efficiency, high data security risks, difficulty in adjusting model parameters, and insufficient credibility of evaluation results in the intellectual property evaluation process of Company D. It significantly improves the company's intellectual property evaluation capabilities, data processing efficiency, and decision-making reliability, and has won unanimous recognition and high praise from within the company, proving the outstanding practical value and technical advantages of the present invention in practical applications.
