ML internals: Synthetic Minority Oversampling (SMOTE) Technique

Domino Data Lab

We present the inner workings of the SMOTE algorithm and show a simple “from scratch” implementation of SMOTE. 2002) do not present a rigorous mathematical treatment for this modification, and the suggested median correction appears to be purely empirical-driven.

Changing assignment weights with time-based confounders

The Unofficial Google Data Science Blog

Just as in ramp-up, making inferences while ignoring the complexity of time-based confounders that are present can lead to biased estimates. This post will discuss how to use data from a MAB to get unbiased estimates. Thus we have conditional ignorability no matter how many time-based confounders are present. 2015): 37-45. [3]
