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: 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 …

End-to-End Machine Learning: Abalone Prediction in R

End-to-End Machine Learning: Abalone Prediction in R Abalone prediction is a machine learning task that involves identifying the age of an abalone, which is a type of sea snail, based on certain characteristics such as the abalone’s length, diameter, height, and weight. Understanding the age of the abalone can be useful for both the commercial …

Evaluate Machine Learning Algorithm – repeated kfold cross validation in R

Evaluate Machine Learning Algorithm – repeated kfold cross validation in R Evaluating the performance of a machine learning algorithm is an important step in understanding how well it will work on new, unseen data. One popular method for evaluating the performance of an algorithm is called “repeated k-fold cross validation.” In repeated k-fold cross validation, …
