Building Better Playlists: Spotify Integration

For somebody who takes a lot of pride in their playlists, mine are pretty sub-par. Sure, I may like the songs, but the order of playback leaves a lot to be desired — Pitbull and The Veronicas certainly belong in the same playlist, but you might not want their top…

Extracting Colour Palettes with Unsupervised Learning

Color combination analysis with chained clustering — For a recent project I needed to find a method to determine which colour palettes were present in a large dataset of artworks, ideally without any input from myself! This task aligned itself to the unsupervised technique of clustering and can be divided into two steps: Extracting commonly occurring colours. …

A single technique to model forest fires, pandemics and economies

Exploring interacting agent modelling in Python — Pandemics, bushfires and economic crisis. Not only the menu for the last year but a small subset of the phenomena that can be modelled under the framework of agent based modelling (ABM). ABM is well suited to understanding how complex behavior emerges in systems based on simple interactions between the…

The Surprising Pattern of Food and Service Deserts in Victoria

Access to groceries, banks and other basic services in Victoria varies with income, but not the way you may think. — The range and accessibility of basic services such as supermarkets and banks varies along with average income between neighboring postcodes in Victoria, Australia. However, unlike the US where “banking deserts” are leaving low-income communities without access to financial services and western Sydney where “food deserts” are limiting access to groceries…

Comparison of Dimensionality Reduction Techniques for Image Art Style Embeddings

This task was undertaken as part of a proof of concept for Look and Learn, an online library of high definition historical pictures. — In the previous story, I developed a model to encode the art style of an image into a vector in higher dimensional space, where the euclidean distance between vectors represents how visually similar the images are. For an image recommendation system to use these embeddings, the vector for every image…

Developing Art Style Embeddings for Visual Similarity Comparison of Artworks

This task was undertaken as part of a proof of concept for Look and Learn, an online library of high definition historical pictures. — The aim of this exercise is to find a function that transforms images into embedding vectors where the euclidean distance between vectors represents how visually similar the images are. …

Google Maps sucks for cyclists

But it doesn’t need to stay that way. — Don’t get me wrong, I love Google Maps. Its a borderline miraculous service that has given me superb driving directions, public transport timetables, and walking routes. All over the world. For free. However, when I tried to get cycling directions to a store a short distance across town I encountered…
