dnn neural network

BP (Back Propagation) network is a multi-layer feed-forward Network trained by the error inverse propagation algorithm, which was proposed by a team of scientists led by Rumelhart and mccelland in 1986, it is one of the most widely used neural networks. The BP network can learn and store a large number of input-output

This paper aims at constructing probabilistic language model of Chinese based on Fudan Chinese corpus and neural network model.A goal of the statistical language model is to find the joint distribution of different words in the sentence, that is to find the probability of the occurrence of a word sequence, a well-trained statistical language model can be used in speech recognition, Chinese input method, mac

The role of cross-entropy One of the most common ways to solve multi-classification problems with neural networks is to set N output nodes at the last layer, whether in shallow neural networks or in CNN, for example, the last output layer in alexnet has 1000 nodes:And even if the ResNet cancels the all-connected layer, it will have a 1000-node output layer at the end: In general, the number of nodes in the
