What is Hierarchical Clustering? Hierarchical clustering is a method of cluster analysis that seeks to build a hierarchy of clusters. It is particularly useful for data that does not naturally fall into distinct groups. Unlike other clustering methods, hierarchical clustering does not require the nu...
What is Naive Bayes? Naive Bayes is a family of probabilistic algorithms based on Bayes’ Theorem, which is used for classification tasks. The term “naive” refers to the assumption that the features in a dataset are independent of each other, which is rarely the case in real-world s...
Understanding XGBoost XGBoost is an open-source software library that provides a gradient boosting framework for C++, Java, Python, R, and Julia. It is designed to be highly efficient, flexible, and portable. The algorithm is renowned for its speed and performance, making it a favorite among data sc...
What is LightGBM? LightGBM is a gradient boosting framework that uses tree-based learning algorithms. It is designed to be distributed and efficient, making it ideal for large-scale data processing. Unlike traditional gradient boosting methods, LightGBM grows trees leaf-wise rather than level-wise, ...
What is CatBoost? CatBoost, short for Categorical Boosting, is an open-source machine learning library that is designed to handle categorical data efficiently. Unlike other gradient boosting libraries, CatBoost automatically deals with categorical features, eliminating the need for extensive preproc...
