Machine Learning Mastery: A Practical approach to Simple Linear Regression using R

A Practical approach to Simple Linear Regression using R   Simple Linear Regression is a statistical method that allows us to summarize and study relationships between two continuous (quantitative) variables. One variable denoted x is regarded as an independent variable and other one denoted y is regarded as a dependent variable. It is assumed that …

Machine Learning Mastery: Linear Regression Using Tensorflow

Linear Regression Using Tensorflow   Brief Summary of Linear Regression Linear Regression is a very common statistical method that allows us to learn a function or relationship from a given set of continuous data. For example, we are given some data points of x and corresponding y and we need to learn the relationship between them that is called …

Machine Learning Mastery: Linear Regression using sklearn

Linear Regression using sklearn   Linear Regression is a machine learning algorithm based on supervised learning. It performs a regression task. Regression models a target prediction value based on independent variables. It is mostly used for finding out the relationship between variables and forecasting. Different regression models differ based on – the kind of relationship …

Machine Learning Mastery: Locally weighted Linear Regression

Locally weighted Linear Regression   Linear regression is a supervised learning algorithm used for computing linear relationships between input (X) and output (Y). The steps involved in ordinary linear regression are: Training phase: Compute  to minimize the cost. Predict output: for given query point , As evident from the image below, this algorithm cannot be used for making predictions …
