I would like to share with you a small tool I have discovered this year which is very useful; Violin Plot!
Lately at work we had the opportunity to propose new Uses Cases to develop around Ericsson Expert Analytic and data science in the operator’s network. We propose to work on an automated system to detect machines in the subscriber base.
Part of my task in the Data Science Team is to participate in the deployment of our development environment. This will be the first, of a series of articles about the environment we use at work.

We had a rough idea of how many classes were present but nothing was sure, we discovered the Kolmogorov–Smirnov test a very efficient way to determine if two samples are significantly different from each other. I will give you a bit of context on the Kolmogorov–Smirnov test and walk you though one problem we solved with it. A bit of theory Rejecting the null hypothesis. That sounds…Continue Reading “Kolmogorov–Smirnov test”
