Difference between Bagging and Random Forest
Before we get to Bagging, let’s take a quick look at an important foundation technique called the bootstrap. The bootstrap is a powerful statistical method for estimating a quantity from a data sample. This is easiest to understand if the quantity is a descriptive statistic such as a mean or a standard deviation. Let’s … See more I've created a handy mind map of 60+ algorithms organized by type.
