The application relates to the technical field of index creation, and provides an index creation method based on thumbnail comparison of numeric data in Opengauss, which comprises the following steps: judging whether the column of the data to be created is of the numeric type, setting an optimization mark for thumbnail comparison in the tuple in a target table according to the judgment result; scanning the tuples in the target table one by one, saving the value of the index column of the tuple according to the optimization mark of the tuple; sorting the tuples in step S2 through a thumbnail comparison algorithm; and inserting the tuples sorted in step S3 into a btree index. According to the index creation method based on thumbnail comparison of numeric data in Opengauss of the exemplary embodiment of the application, the single int data direct comparison is optimized from the character array comparison mode in the prior art, the comparison algorithm performance is improved, the number of CPU operation times is reduced, the time consumption of the numeric data type index creation is greatly reduced, the original algorithm overhead in the prior art is reduced, and the index creation efficiency is improved.

The invention is systems and methods directed to a method of training a machine learning model that is particularly adept at handling numeric data and is able to learn from prior models trained using the same method.

The invention discloses a medical data desensitization traceability auditing method based on differential privacy, and relates to the technical field of medical data security, and the method specifically comprises the following steps: collecting two types of medical data and standardizing the format, extracting the clinical decision weight of numeric data and the privacy risk tag of text data, and implementing differential desensitization based on the weight and the tag, the method comprises the following steps: adding weight-associated Laplacian noise to numeric data, hierarchically replacing text data or masking key information, embedding a unique traceability identifier and verifying privacy compliance and availability, finally establishing a closed-loop auditing mechanism, supporting identifier extraction, compliance verification and leakage tracking, continuously optimizing related parameters and strategies based on feedback, and finally realizing the real-time auditing of the privacy. And the data security and traceability are effectively ensured.

An information processing system comprising: an input portion configured to receive, as input to a main storage device that stores data including an attribute having a unit, input information comprising numeric data for the attribute; an arithmetic portion, configured to evaluate, based on the input information and unit information, whether the numeric data is appropriate when regarded as being expressed in each of the plurality of unit candidates, wherein the unit information includes information on a plurality of unit candidates that may be assigned to the attribute, information on a specified unit of the attribute that is selected from the plurality of unit candidates, and information on conversion from the plurality of unit candidates to the specified unit; and the display portion configured to display, on a display device, a unit candidate, which differs from the specified unit, from among the plurality of unit candidates that are evaluated as appropriate.

A processor comprises a memory to store numeric data in bit plane format and circuitry coupled to the memory to perform matrix operations on the stored data using adders. The bit plane format allows dynamic variations in bit sizes of values. A system includes a memory to store numeric data in bit plane format, a processor coupled to the memory, and a matrix multiplication module to perform matrix multiplication using adders. A method involves storing numeric data in bit plane format, retrieving the stored data, and performing matrix operations using adders. The processor, system, and method enable faster processing and reduced memory consumption compared to consecutive aligned bit sequences.

This invention discloses an AI-based method and system for collecting price information in the textile industry. The method includes the following steps: S1, Image Repair and Cleaning: Processing the tabular price quote images from textile factories, retaining only the table area; S2, Table Cropping: Cropping the repaired image according to the table format, dividing it into multiple smallest sub-table images without table sub-tables; S3, Sub-table OCR Recognition: Extracting the row, column, and header names of the sub-tables, as well as corresponding text and / or numeric data, and returning sub-table data containing complete structured information; S4, Header Row to Column Conversion: Extracting the header row information and converting it into column information to generate a uniformly formatted intermediate table; S5, Multi-Table Concatenation and Integration: Concatenating and integrating multiple intermediate tables into a single large table with a unified format. Compared with existing technologies, this invention eliminates the need for manual secondary processing, significantly reducing the cost of price information collection and significantly improving the efficiency, accuracy, and timeliness of data collection.
