WebNov 6, 2024 · I am using CTC in an LSTM-OCR setup and was previously using a CPU implementation (from here). I am now looking to using the CTCloss function in pytorch, however I have some issues making it work properly. My test model is very simple and consists of a single BI-LSTM layer followed by a single linear layer. def … WebJul 25, 2024 · Motivation. CTC 的全称是Connectionist Temporal Classification. 这个方法主要是解决神经网络label 和output 不对齐的问题(Alignment problem). 这种问题经常出现在scene text recognition, speech recognition, handwriting recognition 这样的应用里。. 比如 Fig. 1 中的语音识别, 就会识别出很多个ww ...

E.g. using [64, 512, 1, 28] you could squeeze dim3 and use dim4 as the “sequence” dimension (it’s one of the spatial dimension). In this case, you could permute the activation so that the linear layer will be applied on each time step and permute it … images of honey locust tree
