WebCalculates 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 … WebJul 17, 2024 · Breaking down the CTC Loss. The Connectionist Temporal Classification is a type of scoring function for the output of neural networks where the input sequence may not align with the output sequence at every timestep. It was first introduced in the paper by [Alex Graves et al] for labelling unsegmented phoneme sequence.
WebJun 7, 2024 · 1 Answer. Your model predicts 28 classes, therefore the output of the model has size [batch_size, seq_len, 28] (or [seq_len, batch_size, 28] for the log probabilities that are given to the CTC loss). In the nn.CTCLoss you set blank=28, which means that the blank label is the class with index 28. To get the log probabilities for the blank label ... WebConnectionist temporal classification ( CTC) is a type of neural network output and associated scoring function, for training recurrent neural networks (RNNs) such as LSTM networks to tackle sequence problems where the timing is variable. It can be used for tasks like on-line handwriting recognition [1] or recognizing phonemes in speech audio.
WebCTCLoss()对象调用形参说明： log_probs：shape为(T, N, C)的模型输出张量，其中，T表示CTCLoss的输入长度也即输出序列长度，N表示训练的batch size长度，C则表示包含有空白标签的所有要预测的字符集总长度，log_probs一般需要经过torch.nn.functional.log_softmax处理后再送入到CTCLoss中； WebCaffe-With-Warpctc.
