Decision Trees vs Clustering Algorithms vs Linear Regression
In machine learning, Decision Trees, Clustering Algorithms, and Linear Regression stand as pillars of data analysis and prediction. Decision Trees create structured pathways for decisions, Clustering Algorithms group similar data points, and Linear Regression models relationships between variables. In this article, we will discuss how each method has distinct strengths, making them indispensable tools in understanding and extracting insights from complex datasets.
