Webb机器学习之感知机(perceptron)1.感知机模型介绍感知机是一个二分类的线性分类模型，二分类是指输出YYY的分类只有两个值，取+1和-1，线性分类是指模型将训练数据集用一个线性超平面(如果特征空间XXX⊆\sube⊆RnR^nRn,那么该线性超平面就是n-1维)。感知机模型属于判别模型，即通过输入的样本直接学习到 ... WebbThe Perceptron. The original Perceptron was designed to take a number of binary inputs, and produce one binary output (0 or 1). The idea was to use different weights to represent the importance of each input , and that the sum of the values should be greater than a threshold value before making a decision like yes or no (true or false) (0 or 1).
