Getting Started with MLFlow
Marton Trencseni - Sun 10 January 2021 • Tagged with mlflow, tracking
For the last few months I’ve been using MFlow in production, specifically its Tracking component. MLFlow is an open source project for lifecycle tracking and serving of ML models, coming out of Databricks. MLFlow is model agnostic, so you can use with SKLearn, XGBoost, Pytorch, Tensorflow, FBProphet, anything.
Making statistics lie for the 2020 Presidential election
Marton Trencseni - Thu 17 December 2020 • Tagged with ab-testing, trump, politics
After the 2020 US presidential election, the Trump campaign filed over 50 lawsuits and attacked the integrity of the elections by claiming there was voter fraud. One of the last lawsuits was filed in the Supreme Court of the United States by the state of Texas. Here I look at the statistical claims made in this lawsuit that were supposed to show irregularities in the Georgia vote.
