BP neural network matlab code explanation and implementation steps

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 ...

Machine learning -- evaluation of classification algorithms

Problems in classification accuracy If there is a cancer prediction system, input the patient's information to determine whether there is cancer. Is it reasonable to use only classification accuracy to evaluate the quality of the model? If the prediction accuracy of the model is 99.9%, can the model be considered good? If the probability of ca ...

A detailed explanation of RNN and stock forecasting practice (Python)

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 ...

Bayesian classifier as text classification case

Bayesian classifier for text classification Text classification is not only a large module in modern machine learning applications, but also one of the foundations of natural language processing. We can process text data into digital data, and then use Bayes to help us judge a paragraph, or the topic classification, emotional tendency, and eve ...
