Anscombe transform

Why statistics is always misleading ?

Anscombe’s Quartet and Datasaurus demonstrate that statistical values are there for reference only. Does it imply that they are useless ? Well, in this video I tell you about Netflix Prize and how it was “hacked” to demonstrate how important data confidentiality is and how stats can help

The Two-Dimensional Discrete Fourier Transform

The two-dimensional discrete Fourier transform (DFT) is the natural extension of the one-dimensional DFT and describes two-dimensional signals like images as a weighted sum of two dimensional sinusoids. Two-dimensional sinusoids have a horizontal frequency component and a vertical frequen

Lmplot - Seaborn

We go over the entirety of seaborn's lmplot. We talk about factor grids and doing conditional linear regression. We talk about logistic, log transformed and lowess regression. This one was a big one, and a lot of fun, hope you enjoyed! Associated Github Commit: https://github.com/knathani

Integral Transforms Lecture 1: Motivation & Introduction. Oxford Mathematics 2nd Yr Student Lecture

This short course from Sam Howison, all 9 lectures of which we are making available (this is lecture 1), introduces two vital ideas. First, we look at distributions (or generalised functions) and in particular the mathematical representation of a 'point mass' as the Dirac delta function.
