the largest . This results in a more credible classification and a good predictive ability for unknown new samples .Our goal is to look for a hyper-plane, so that the points closer to the super-plane can have greater spacing. That is, we do not consider that all the points must be away from the hyper-plane, we are concerned about the super plane can make all points from its nearest point has the maximum spacing. And the closest point to the hyper-plane is the support vector.Suppose we have N tr

This article mainly introduces the knowledge of Perceptron, uses the theory + code practice Way, and carries out the learning of perceptual device. This paper first introduces the Perceptron model, then introduces the Perceptron learning rules (Perceptron learning algorithm), finally through the Python code to achieve a single layer perceptron, so that readers a more intuitive understanding. 1.
