How to use matlab Linear Neural Network

This article introduces the relevant knowledge of "how to use MATLAB linear neural network". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Linear neural network is the simplest kind of neural network, which can be composed of one or more linear neurons. The difference between the linear neural network and the perceptron is that the neuron transfer function of the linear neural network is a linear function, so the output of the linear neural network can take any value, while the output of the perceptron can only be 0 or 1. Linear neural network has higher convergence speed and accuracy than perceptron, but like perceptron, linear neural network can only solve the problem of linear separation. Each input of the perceptron has an output corresponding to it. Referring to the difference between the output vector and the expected output vector, the weights and thresholds of the network are adjusted so that the sum of squares of the training error is minimum or less than a certain value. This learning rule is the Widrow-Hoff learning rule, which is called LMS (Least Mean Square) algorithm. % define variable
