Perceptron Algorithmis a classification machine learning algorithm used to linearly classify the given data in two parts. It could be a line in 2D or a plane in 3D. It was firstly introduced in the 1950s and since then it is one of the most popular algorithms for binary classification. Mat...

For the Perceptron algorithm, each iteration the weights (w) are updated using the equation: 1 w = w + learning_rate * (expected - predicted) * x Where w is weight being optimized, learning_rate is a learning rate that you must configure (e.g. 0.01), (expected – predicted) is th...
目前,随着人工智能的大热,吸引了诸多行业对于人工智能的关注,同时也迎来了一波又一波的人工智能学习的热潮,虽然人工智能背后的原理并不能通过短短一文给予详细介绍,但是像所有学科一样,我们并不需要从头开始”造轮子“,可以通过使用丰富的人工智能框架来快速构建人工智能模型,从而入门人工智能的潮流。人工智能指的是一系列...
