The generation and preparation of high-quality data sets are achieved through the technical integration of the two methods.

[0007] Furthermore, the high-quality data preparation link based on intelligent data collection technology specifically targets the existing data in the current physical space, and establishes a set of standardized intelligent data collection technology processes to achieve high-quality preparation of test data sets, including four core technical links: automated collection, deep cleaning, intelligent labeling, and fusion quality inspection.

[0009] Furthermore, in step S2, the basic information of the test data set is imported to provide a complete and detailed description of the basic information of the data set for the test data set to be tested, which is the basis for the selection of dimensions and weight design of the subsequent test data set quality assessment, and the basic information required for the test data set includes the following aspects: 1) Field structure of the data set: clarify the specific field composition of the test data set and the specific meaning of each field; 2) Dataset size: Specify the specific data size and number of data items in the test dataset. Generally, the number of data items in the test dataset must be greater than 20,000. 3) Modality type of the dataset: clarify the specific modality and type of the test dataset, including text, voice, image, video, audio, multi-modality, etc.; 4) Task types supported by the dataset: clarify the types of training tasks that the test dataset needs to support in the future, such as unsupervised learning, supervised learning, reinforcement learning, etc. 5) Dataset application scenario classification system: For the quality assessment of high-quality industry data sets, clarify the key industry fields and business scenario systems of the data sets.

[0010] Furthermore, in step S2, the weight design of the test data set indicators is different according to the subject scope and professional level. The specific definition of the artificial intelligence data set is divided into three categories: general data set, industry general data set and industry specialized data set. The three categories of data sets have different evaluation requirements for the specific 12 types of first-level evaluation indicators and 36 types of second-level evaluation indicators; The first-level evaluation indicators include completeness, standardization, accuracy, timeliness, consistency, density, diversity, balance, relevance, originality, traceability, and accessibility, and the second-level indicators included in each first-level evaluation indicator are as follows: Secondary indicators of completeness include: scale completeness, structural completeness, mission completeness, and domain completeness; The secondary indicators of normativity include: formal normativity, privacy normativity, and security normativity; Secondary indicators of accuracy include: content authenticity and field expertise; The secondary indicators of timeliness include: generation timeliness, collection timeliness, processing timeliness, and release and update timeliness; Secondary indicators of consistency include: label consistency, concept consistency; Secondary indicators of density include: sample uniqueness and content information; The secondary indicators of diversity include: feature diversity, type diversity, source diversity, task diversity, domain diversity, and cultural diversity; The secondary indicators of balance include: category balance, source balance; Secondary indicators of relevance include: logical relevance, task relevance, and domain relevance; The secondary indicators of originality include: source originality, content originality; The secondary indicators of traceability include: source traceability, link traceability, and version control traceability; The secondary indicators of accessibility include: ease of acquisition, ease of use, and technical support.

[0011] Furthermore, in step S3, the technical process of autonomous rule detection is: a specific automated operation algorithm, program or model is written through a deterministic rule system or empirical formula for artificial intelligence data set quality assessment to automatically check the quality of the data set, screen out data sets with too low quality in advance, and reduce the cost for subsequent sampling detection and model verification, specifically including: S31. Autonomous identification of dataset knowledge information It aims to efficiently identify and analyze the detailed knowledge and information content of the data set and improve the utilization rate of the data set for the model. It specifically includes two major components: one is shallow information recognition, which is responsible for defining and organizing the classification standards of the data set, including using keyword search, text encoding and decoding, optical character recognition and other technologies to identify data set modality, industry and application scenario label information; the other is deep information extraction, using statistical and machine learning techniques to deeply explore and analyze the inherent patterns and laws in the data set, including but not limited to the correlation between features, abnormal patterns, data distribution characteristics and time series characteristics; S32.

Specific detection methods include simple random sampling, priority sampling, mixed sampling, stratified sampling, systematic sampling, probability proportionate sampling (PPS), convenience sampling, judgment sampling and other methods.

[0013] Furthermore, in step S4, model performance feedback: select a suitable model according to the business scenario and task requirements, and send the evaluated data set into the model for training, and select appropriate model performance verification indicators to verify the model performance. Through the core performance indicators of large model training, the fluctuation of model performance is discovered in time, and the specific quality performance of the evaluated data set is determined by judging the performance of the model on the evaluation indicators; the training performance indicators of the large model specifically include three parts: model training accuracy performance (precision, recall rate, accuracy, F1 Score, root mean square error MSE), model training speed performance (training time, number of iterations, model throughput, model delay, etc.), model training resource consumption (computing resource utilization, memory occupancy, energy consumption per unit time, etc.).

[0014] Furthermore, in step S4, the data set ablation test is performed: multiple different data sets are obtained by changing one or more evaluation dimensions of the original data set, and the same model is trained with different data sets obtained by changing these indicators, and the changes in the model benchmark testing capabilities are tested and verified. The data set ablation test can be used to evaluate and verify the specific contribution of one or more indicator combinations to the model performance; the data set ablation test technical means specifically include data set subset experiments (removing samples of specific categories, reducing the amount of data, disabling certain features, changing data distribution), data set feature screening analysis, etc.
