NetDecoder[{"CTCBeamSearch", alphabet}] 表示一个解码器,对概率向量序列进行解释,给出最有可能的序列解码. NetDecoder[{"CTCBeamSearch", ..., "BeamSize" -> n}] 表示具有指定柱宽度 (beam size) 的解码器.

上图是集成了CTC和beam search的算法过程,其中LM是指language model。 我们把集成了CTC的算法和之前说的基础版的beam search放在一起对比看。集成了CTC的和基础版的beam search差不多,但包括了对beam进行评分的代码:copy beam(第7-10行)和extend beam(15-19行)进行评分。此外,当将beam b扩展一个字符c(第14行...

而常用的CTC解码算法一般有Greedy Search Decode(贪心搜索)、Beam Search Decode(束搜索)、Prefix Beam Search Decode(前缀束搜索)等,其中又以Greedy Search Decode(贪心搜索)和Prefix Beam Search Decode(前缀束搜索)使用的最多,本文将使用Python代码逐一实现上述三种算法。

A Python implementation of beam search decoding (and other decoding algorithms) can be found in theCTCDecoderrepository: the relevant code is located in src/BeamSearch.py and src/LanguageModel.py. TensorFlow provides the ctc_beam_search_decoder operation, however, it does not include a LM. ...
