Calculus rules to live by

Calculus is a big topic, but by and large, there are quite specific aspects of calculus that come into machine learning and in particular deep learning algorithms. This article is not intended to explain how and why things are as they are; rather it's my own personal cheat sheet for when I need to remember... Continue Reading →

Data structures for deep learning

I recently completed the Udacity Deep Learning Nanodegree (highly worth doing by the way), which focuses on implementing a variety of deep learning architectures using PyTorch. At the outset, it's pretty fundamental to understand the data structures you'll be encountering as inputs to and outputs from your neural network architecture. What I noticed was that...

Emerging from Data Science Intensive

In September & October I was fortunate enough to attend the Data Science Intensive Program (DSI) in Cape Town. In a word: WOW! The program brought together 16 students from 7 African countries for 8 very intensive weeks with an ambitious goal: To ensure that anyone who completes the DSI is able to contribute significant...

SQL CheatSheet

I've just worked through Imtiaz Ahmad's Master SQL for Data Science on Udemy and it was a thoroughly enjoyable, morale-boosting experience! He build on each concept so you never feel left behind or perplexed at how he arrived at a solution, and as promised there are a gazillion exercises so by the time you're done you feel like...

Naturally I googled (using bing!) and found this wonderful online resource www.datascienceatthecommandline.com. After reading the section entitled "A Real-world Use Case" involving data for New York... Continue Reading →

Thoughts on keeping on going

I had an email today from a reader ("K") who tried the Learn Python Challenge on Kaggle and (as does happen!) got to about Day 4 and then abandoned ship and went in search of more new stuff... The question is how to keep on going - when you get stuck, bored, de-motivated or perhaps even... Continue Reading →

So stoked to be attending Data Science Intensive later this year - "first of its kind in Africa": 8 weeks solving real world problems, I can hardly wait :).

Perspectives after a no-screens break

Having just returned from one of those "no screens" holidays, I'm feeling super-balanced about life again (and also a little afraid that I may have forgotten everything I've been learning)! Being in the Addo Elephant Park reminded me keenly of my original inspirations for starting this journey - if I could do some good in... Continue Reading →
