在机器学习中对于分类结果的描述,一般有四种:true positive, true negative, false positive 和 false negative. Precision, Recall, F-score等的测量标准都是建立在这四个描述上.下面是从wiki上截下来的图: 首先,对于横向True condition和纵向Predicted condition相交的四个格子就是需要记住的四个分类描述. 如何记住?以True condition + Predicted conditi…

1. Main Point 0x1:行文框架 第二章:我们会分别介绍NNs神经网络和PR多项式回归各自的定义和应用场景. 第三章:讨论NNs和PR在数学公式上的等价性,NNs和PR是两个等价的理论方法,只是用了不同的方法解决了同一个问题,这样我们就形成了一个统一的观察视角,不再将深度神经网络看成是一个独立的算法. 第四章:讨论通用逼近理论,这是为了将视角提高到一个更高的框架体系,通用逼近理论证明了所有的目标函数都可以拟合,换句话说就是,所有的问题都可以通过深度学习解决.但是通用逼近理论并没有告诉…

##Linear Regression with One Variable Linear regression predicts a real-valued output based on an input value. We discuss the application of linear regression to housing price prediction, present the notion of a cost function, and introduce the gradi…
