Doing Machine Learning is frustrating. Our mission is to change that.

This blog is a collection of my thoughts on how we think about ML, how we do ML and what we want to achieve with ML.

Main topics:

  • How to connect business value to Data Science?

  • How to organise your team to deliver?

  • How to write better code as a Data Scientist, and why does that matter?

  • Article reviews

  • More unpopular opinions

I want to focus on new and orthogonal ideas rather than reiterating cliches.

Who am I?

I am Laszlo. I am an ex-quant portfolio manager (commodities and futures), ex-mobile game analyst (Candy Crush & co.) and ex-startup Head of Data Science (market intelligence for Tier 1 investment banks).

I do machine learning professionally for more than 15 years.

I now run a startup consultancy helping companies get up to speed with their ML efforts. Get in touch if you want to learn more: https://hypergolic.co.uk/contact/
