Practice multiple choice questions on Regression with answers. This is one of the fundamental techniques in Machine Learning which is widely used in basic problems.

Machine Learning (ML)

Advantages and Disadvantages of Logistic Regression

In this article, we have explored the various advantages and disadvantages of using logistic regression algorithm in depth.

Performance metrics in Classification and Regression

In this post, we will look at different performance metrics for classification and regression. For regression, metrics are Mean absolute error, Mean squared error, R-Square and many more. For classification, the metrics are accuracy, precision, recall and many more.

Linear vs Logistic Regression

We have explored the differences between Linear and Logistic regression in depth. We looking into the applications of Linear and Logistic regression along with a basic background.

Machine Learning (ML)

Data Analysis using Regression

In this article, we have clarified the most usually utilized kinds of regressions in information science and its application in data analysis

Machine Learning (ML)

Logistic Regression

Logistic Regression is an efficient regression algorithm that aims to predict categorical values, often binary. It is widely used in the medical field to classify sick and healthy individuals and areas that need to determine a client's risk such as financial companies.

Machine Learning (ML)

Principal Component Regression (PCR)

Principal Component Regression (PCR) is an algorithm for reducing the multi-collinearity of a dataset. PCR is basically using PCA, and then performing Linear Regression on these new PCs. The key idea of how PCR aims to do this, is to use PCA on the dataset before regression.

Machine Learning (ML)

Ridge Regression

Ridge regression is an efficient regression technique that is used when we have multicollinearity or when the number of predictor variables in a set exceed the number of observations. It uses L2 regularization and solves the problem of overfitting. Concepts of overfitting and regularization is basis

Summary of Regression Techniques

Regression is a technique based on statistics to model the relationship between a set of variables to make predictions on unseen data. We explored are Linear, Logistic, Polynomial, Ridge, Lasso, Elastic Net, Stepwise regression.

Artificial Intelligence

Decision Trees

Decision Tree is a popular machine learning algorithm mainly used for classification. Concepts of entropy and information gain are required to apply decision tree for a data set. It is used for non-linear classification and regression Learn through an example
