Code README linear_regression_project This project implements linear regression using both gradient descent and normal equations. The project includes several components to demonstrate the concepts of linear regression and its implementation in Python. ...
Linear Regression Python Implementation In this section, we will learn how to implement the Linear Regression algorithm from scratch only using fundamental libraries like Numpy, Pandas, and Matplotlib. We will implement Univariate Linear Regression, which contains only one dependent and one independent va...
Regression is performed on continuous data, while classification is performed on discrete data. Regression can be anything from predicting someone's age, the house of a price, or value of any variable. Classification includes predicting whatclasssomething belongs to (such as whether a tumor is beni...
我们的目标和单变量线性回归问题中一样,是要找出使得代价函数最小的一系列参数。多变量线性回归的批量梯度下降算法为: 求导数后得到: (3)向量化计算 向量化计算可以加快计算速度,怎么转化为向量化计算呢? 在多变量情况下,损失函数可以写为: 对theta求导后得到: ...
Simple Linear Regression Data set and code for ipython notebook pleace click the github link below. Data from 2016 shanghai Annals of Statistics. In statistics, simple linear regression is a linear regression model with a single explanatory variable. That is, it concerns two-dimensional sample po...
通过看其他人在kaggle上分享的notebook以及自己的一些理解,记录一下Linear Regression的学习过程,也算是完成作业中的report.pdf。 二、Linear Regression(预测PM2.5) 1、准备工作 (1)作业要求(如图一所示) 图一 (2)train.csv、test.csv 链接:https://pan.baidu.com/s/1ZeOASD7SdyMUYwjo0uDaqA ...
In addition, to observe whether the proposed SMOTE-RkNN algorithm is irrelevant with the specific classifier, we used three different classification algorithms, namely Classification and Regression Tree (CART) [28], Linear Discriminant Analysis (LDA) [8], and Gaussian Naive Bayes (GNB) [48], for...
