Understanding Bootstrap Sampling: Where Euler’s Number Meets Random Forests
A common problem involves drawing a sample of size n from a set of n elements, with replacement. For example, in Random Forests, each decision tree is trained on a bootstrap sample drawn n times with replacement from the training data. A natural question is: how many unique examples can we expect in such a sample? Since sampling is done with replacement, some examples are likely selected multiple times, while others may not be selected at all.

Beyond 3D: Generalizing the Vector Cross Product
Imagine you are working in three-dimensional space and have two directions. You want to find a third direction that is perpendicular to both of them. In this setting, there's a well-known solution: the cross product. When applied to the two original directions, it produces a new one that is exactly orthogonal to both.
