(raw logits), you either need to pass it through an additionaltorch.nn.functional.softmaxor you can passlog_probs_input=Falseto the decoder. Your output should be BATCHSIZE x N_TIMESTEPS x N_LABELS so you may need to transpose it before passing it to the decoder. Note that if you ...
ctcdecode is an implementation of CTC (Connectionist Temporal Classification) beam search decoding for PyTorch. C++ code borrowed liberally from Paddle Paddles'DeepSpeech. It includes swappable scorer support enabling standard beam search, and KenLM-based decoding. If you are new to the concepts of CTC...

例如我们选择keras yolo3进行文字检测,选择pytorch进行文字识别,去掉文字方向检测(假定输入的图片绝大多数是方向正确的),那么即可对chineseocr的源代码进行大幅精简。在model.py代码的基础上进行修改,去繁存简,对识别能力进行封装,方便提供给其它应用程序使用。修改后的核心代码如下: ...
...Pytorch 中的实现:我们为损失函数创建一个新类,该类继承了抽象类 nn.Module ,并且固定的margin 为 0.2。 我们还更改的类的两个主要方法 __init__和 forward。...所以在计算损失时对于零值和负值“relu”返回零,这是我们需要的结果。我们需要的损失主要就是当括号内的值为正值时的数值,因此 Siamese 模型...
This collection contains the large version (114M) of the Dutch speech recognition model with a FastConformer encoder and a Hybrid decoder (joint RNNT-CTC loss). The model has a vocab size of 1024 and emits text with punctuation and capitalization. PublisherNVIDIA Latest Version1.0.0 Modifie...
