机器学习基础算法python代码实现可参考:machine_learning_algorithms 1 原理 1.1 引入 首先,在引入LR(Logistic Regression)模型之前,非常重要的一个概念是,该模型在设计之初是用来解决0/1二分类问题,虽然它的名字中有回归二字,但只是在其线性部分隐含地做了一个回归,最终目标还是以解决分类问题为主。 为了较好地掌握 ...
Linear Machine Learning Algorithms This section provides examples of how to use 4 different linear machine learning algorithms for regression in Python with scikit-learn. 1. Linear Regression Linear regression assumes that the input variables have a Gaussian distribution. It is also assumed that input...

Ordinary Least Squares Regression | Python By: Rajesh P.S.Machine Learning is all about developing algorithms (models) that can predict output values with an acceptable level of error, using a set of known input parameters. Ordinary Least Squares (OLS) is a popular form of regression used in...
Logistic Regression is one of the most simple and commonly used Machine Learning algorithms for two-class classification. It is easy to implement and can be used as the baseline for any binary classification problem. Its basic fundamental concepts are also constructive in deep learning. Logistic re...
