Abstract: A data encoding and decoding system, method, and apparatus for efficient feature data processing. The method obtains auxiliary encoding information of feature data and determines scale parameter values corresponding to feature elements. After quantizing these values to integers, the method selects a subset of scale parameter quantization values exceeding a preset threshold. Feature elements corresponding to these selected values are extracted from the feature data and undergo entropy encoding based on their corresponding quantization values. For unencoded feature elements, the method determines appropriate replacement elements. The process combines entropy encoded elements with replacement elements to create an efficient encoded data stream, which can later be decoded through a reverse process. This selective encoding approach significantly reduces data size while maintaining essential information for accurate reconstruction.
