After the last post discussing set theory here, the next logical step is to discuss the concept of probability theory. The theory of probability is…
Recently I have been undertaking a project to commit my accrued notes relating to statistics online. I want to do this for a few reasons:…
Nearest neighbour algorithms classify unlabelled instances (data observations/ cases) by assigning them to a class which is the most similar found in the training data.…
