Introduction to Random Forests for Machine Learning at the London Python Meetup

Last night I had the pleasure of returning to London Python to introduce Random Forests (this builds on my PyConUK 2016 talk from September). My goal was to give a pragmatic introduction to solving a binary classification problem (Kaggle’s Titanic) using scikit-learn. The talk (slides here) covers: Organising your data with Pandas Exploratory Data Visualisation […]

Practical ML for Engineers talk at #pyconuk last weekend

Last weekend I had the pleasure of introducing Machine Learning for Engineers (a practical walk-through, no maths) [YouTube video] at PyConUK 2016. Each year the conference grows and maintains a lovely vibe, this year it was up to 600 people! My talk covered a practical guide to a 2 class classification challenge (Kaggle’s Titanic) with […]

Some notes on building a conda recipe

I’ve spent the day building a conda recipe, the process wasn’t super-smooth, hopefully these notes will help others and/or maybe you can leave me a comment to improve my flow. The goal was to learn how to use conda to distribute a package that ordinarily I’d put on PyPI. I’m using Linux 64bit (Mint 18 […]

Results for “Which version of Python (2.x vs 3.x) do London Data Scientists use?”

Over the last week I’ve surveyed my PyDataLondon meetup community (3,400+ members) to ask “Which version of Python do you use at work and at home?”. The goal is to gain evidence about which versions of Python are used by Data Scientists. This will help tool developers so they can make evidence-based decisions (e.g. this Dask […]

Convert London Oyster (Travel) PDFs to Pandas DataFrames

As a part of analysing Emily’s allergic rhinitis we want to test whether using the London Underground (notoriously dirty!) increases the likelihood of sneezing. The “black snot” phenomenon is well known to Londoners, possibly the particulates (from oil and metal) cause irritation. You can get updates via our allergic rhinitis analysis mailing list (very very […]
