In this tutorial, we'll discuss the details of generating different synthetic datasets using the Numpy and Scikit-learn libraries. We'll see how different samples can be generated from various distributions with known parameters. We'll also discuss generating datasets for different purposes, such as regression, classification, and clustering. At the end we'll...
