1. Introduction and structural parameters of BP neural network
Neural network is a common mathematical model in machine learning. It processes information by constructing a structure similar to the synaptic connection of brain nerves. In the process of applying neural network, the units dealing with information are generally divided into t ...

Recurrent neural network (RNN) is designed based on the recursive nature of sequential data (such as language, speech and time series). It is a feedback type of neural network. Its structure includes loop and self repetition, so it is called "loop". It is specifically used to process sequence data, such as generating text word by word ...

Method for obtaining picture mean and variance
In domain adaptive change, or when processing data sets, it is often necessary to analyze the mean and variance of images or data sets
By analyzing the mean and variance, we can efficiently obtain the data distribution, especially the large data set
Therefore, here we record and introduce the ac ...

For the general classification, we import the data into the neural network, which tells us what kind it is. For some necessary cases, we need to know how the neural network makes judgment, and which parameters of the input data affect the judgment of the neural network. Therefore, the paper Learning Deep Features for Discriminat ...
