机器学习基石笔记-Lecture 2 Perceptron learning algorithm 感知机学习,从二分类问题引入。 perceptron的思想其实来自于神经元。当刺激超过某一阈值时,神经元被激活。 把刺激程度表示为变量的线性组合,与阈值比较,确定分类。 对h(x)的形式简化 形如上式的h(x)的全体就是一个假设集合H. 接下来的需要使用一种演算...

This is not true for the fourth input, but the algorithm does converge on the sixth presentation of an input. The final values are W(6) = [−2 −3] and b(6) = 1. This concludes the hand calculation. Now, how can you do this using the train function? The following code ...
