K-Nearest Neighbors (KNN): Solving Classification Problems

Originally posted by Michael Grogan. 

In this tutorial, we are going to use the K-Nearest Neighbors (KNN) algorithm to solve a classification problem. Firstly, what exactly do we mean by classification?

Classification across a variable means that results are categorised into a particular group. e.g. classifying a fruit as either an apple or an orange.

The KNN algorithm is one the most basic, yet most commonly used…

The Exponential Mean: Alternative to Classic Means

Given n observations x1, ..., xn, the generalized mean (also called power mean) is defined as 

The case p = 1 corresponds to the traditional arithmetic mean, while p = 0 yields the geometric mean, and p = -1…

Surprising Correlation Found in Covid-19 Data

It took me about 30 minutes to notice a spectacular correlation between two core metrics related to the virus, allowing me to make better predictions about the evolution of this pandemic in USA, and to provide possibly the best advice on how to reduce your risk of exposure, or at least how to buy some time in the war against this virus. 

First, many metrics are useless, you need to pick up the most reliable ones. For instance, the number of people who officially tested positive is…

Create Transformed, N-Dimensional Polygons with Covariance Matrix

The covariance matrix has many interesting properties, and it can be found in mixture models, component analysis, Kalman filters, and more. Developing an intuition for how the covariance matrix operates is useful in understanding its practical implications. This article will focus on a few important properties, associated proofs, and then some interesting practical applications, i.e., extracting transformed polygons from a Gaussian mixture's covariance matrix.

I have often found that…
