Pytorch ctc decode

WebJul 13, 2024 · The limitation of CTC loss is the input sequence must be longer than the output, and the longer the input sequence, the harder to train. That’s all for CTC loss! It solves the alignment problem which make loss calculation possible from a long sequence corresponds to the short sequence. The training of speech recognition can benefit from it ...

GitHub - parlance/ctcdecode: PyTorch CTC Decoder …

WebBuilds an instance of CTCDecoder. Parameters: lexicon ( str or None) – lexicon file containing the possible words and corresponding spellings. Each line consists of a word and its space separated spelling. If None, uses lexicon-free decoding. tokens ( str or List[str]) – file or list containing valid tokens. WebThe Connectionist Temporal Classification loss. Calculates loss between a continuous (unsegmented) time series and a target sequence. CTCLoss sums over the probability of possible alignments of input to target, producing a loss value which is differentiable with respect to each input node. choiceadvantage helpline https://needle-leafwedge.com
