Super detailed explanation of CTC theory and actual combat

CTC introduction For speech recognition, the input of training data is a piece of audio and the output is its transcribed text, but we don't know how to align letters and speech. This makes training speech recognition more complex than it seems. It is very difficult and error prone for people to mark this alignment, because the boundaries ...

Neural network -- Understanding BP neural network from code

As soon as we mention the back-propagation algorithm, we unconsciously think of the derivation of random gradient descent, sigmoid activation function and the back-propagation law that makes the head bigger. Even after learning the principle of back-propagation neural network, we are still confused. Here, we recommend a textbook Python neural n ...
