What is the method of adjusting matlab perceptron?
This article mainly explains "what is the method of matlab perceptron adjustment", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let Xiaobian take you to learn "what is the method of matlab perceptron adjustment"!
The perceptron is tuned by the mae function, which is a network performance function that measures system performance in terms of mean absolute error. Other performance functions include mse: mean square error sse: sum of squares of errors

% After training, calculate the average absolute difference y=sim(net,p);e=t-y;perf=mae(e);% The average absolute difference is 0.
