标准范围

ISO/IEC 15938-17:20 22本文档将神经网络编码（NNC）指定为经过训练的神经网络的参数/权重的压缩表示以及压缩表示的解码过程，补充了神经网络现有（交换）格式中的网络拓扑描述。它建立了压缩方法的工具箱，指定（在适用的情况下）压缩比特流的结果元素。本文档没有为神经网络的传输指定完整的协议，而是侧重于网络参数的压缩。仅规定了现有交换格式内的语法格式、语义、相关解码过程要求、参数稀疏化、参数变换方法、参数量化、熵编码方法和集成/信令，而其他事项如预-处理、系统信令和复用、数据丢失恢复和后处理被认为超出了本文档的范围。另外，在解码器内执行的内部处理步骤也被认为超出了本文档的范围；只有外部可观察的输出行为需要符合本文件的规范。

ISO/IEC 15938-17:2022 This document specifies Neural Network Coding (NNC) as a compressed representation of the parameters/weights of a trained neural network and a decoding process for the compressed representation, complementing the description of the network topology in existing (exchange) formats for neural networks. It establishes a toolbox of compression methods, specifying (where applicable) the resulting elements of the compressed bitstream.
This document does not specify a complete protocol for the transmission of neural networks, but focuses on compression of network parameters. Only the syntax format, semantics, associated decoding process requirements, parameter sparsification, parameter transformation methods, parameter quantization, entropy coding method and integration/signalling within existing exchange formats are specified, while other matters such as pre-processing, system signalling and multiplexing, data loss recovery and post-processing are considered to be outside the scope of this document. Additionally, the internal processing steps performed within a decoder are also considered to be outside the scope of this document; only the externally observable output behaviour is required to conform to the specifications of this document.
