Getting results vs Understanding

Alexander Pope is famously quoted as saying: A little learning is a dangerous thing; drink deep, or taste not the Pierian spring: there shallow draughts intoxicate the brain, and drinking largely sobers us again. I've been thinking about these words the past few days as I worked on my latest challenge: a text classifier using... Continue Reading →

Small simple datasets for practising

It's all very well downloading complex datasets from Kaggle and similar sources to play with - they're amazing for learners because the data is always less clean than you would have hoped, more complex than you anticipated, and every bit as interesting as promised. BUT if you're learning a new concept it's easier to have... Continue Reading →

GeoPandas – a detailed example

Dear World, Please send me more geographical data to plot so I can keep on using GeoPandas... Love from Sho't Left I can't believe how much fun this library is! So my goal was to find a way to map assessment ratings by region, showing the overall result for the region, as well as the... Continue Reading →

Which districts are my cities located in?

GeoPandas gets more and more exciting as the day wears on :). I've just discovered how ridiculously easy it is to take a set of cities and relate them to their corresponding districts, states or provinces and then plot the outcomes. Fanfare for... the marvellous GeoPandas spatial join! Here's a quick how-to guide to setting... Continue Reading →

Multivariate regression

So: with linear regression (aka simple linear regression) we have one feature which we are using to predict a dependent value (for example number of rooms as a predictor of house price). With multivariate regression (aka multiple linear regression) we simply have multiple features which could be used to predict that dependent value (for example... Continue Reading →

Polynomial regression

Polynomial regression is a considered a special case of linear regression where higher order powers (x2, x3, etc.) of an independent variable are included. It's appropriate where your data may best be fitted to some sort of curve rather than a simple straight line. The polynomial module of numpy is easily used to explore fitting the best...

Yes I can API!

I have a "real" assignment (for work as opposed to study) to do some data visualizations using maps. It's been a journey of over a week to get to the place where I'm ready to start, and the journey has had some educational detours along the way that I thought I'd share. Naturally, because I'm...
