Description
Technical Field
[0001] The present invention relates to the technical field of data cleaning and processing, and particularly to a big data cleaning method based on deep learning and data feature matching. Background Art
[0002] In the modern information storage and communication fields, data integrity and reliability face various complex challenges. Especially in high-noise electromagnetic environments, unstable storage media, and high-speed data interaction scenarios, traditional data cleaning and error correction methods often struggle to ensure accurate data recovery and long-term availability.
[0003] Currently, the mainstream data processing methods for electromagnetic interference and storage media noise mainly include low-pass filtering, interpolation reconstruction, error correction coding (ECC), data redundant storage (RAID), etc. However, these methods have obvious limitations in practical applications: Traditional low-pass filtering or interpolation algorithms are difficult to effectively remove high-frequency non-linear interference, resulting in signal distortion still existing and affecting data accuracy. Methods such as ECC usually rely on fixed redundant bits for error correction, but in a strong interference environment, data errors beyond the ECC error correction ability will accumulate, ultimately leading to data irrecoverability.
