BP Neural Network Algorithm in Machine Learning

by

The BP neural network (Back Propagation) is a multi-layer network that propagates signals forward and errors backward. This network has very strong computational capabilities and can solve many nonlinear problems by analyzing the nonlinear mapping relationship between input and output variables through training samples. 1. Structure of BP Neural Network The structure of the BP … Read more

BP Neural Network: An Iterative Network That Continuously Improves

1 Algorithm Introduction From the name, we can see that the BP neural network can be divided into two parts: bp and neural network. Here, bp is the abbreviation for Back Propagation, which means reverse propagation. The BP network can learn and store a large number of input-output mapping relationships without needing to reveal the … Read more
