Nov 30, 2023 24 min read. Updated By Chainika Thakar. (Originally written by Kshitij Makwana and Satyapriya Chaudhari) In the realm of machine learning, classification is a fundamental tool that enables us to categorise data into distinct groups. Select some reasonably representative ML classifiers: linear SVM, Logistic Regression, Random Forest, LightGBM (ensemble of gradient boosted decision trees), AugoGluon (fancy automl mega-ensemble). Set up sensible hyperparameter spaces. Run every classifier on every dataset via nested cross-validation. Plot results.

Classification in machine learning is when the feature to be predicted contains categories of values. Each of these categories is considered as a class into which the predicted value falls and hence has its name, classification. An example of this could be predicting the parts of speech (verb, noun, adjective, etc.) of words within a given text.
