Anthropomorphising the algorithm

Leading on from my last blog post conclusion that holding algorithms accountable is a bit of a daft idea, I want to thank Richard Nota for this wonderful comment on The Conversation article posted by Andrew Waites in our slack channel Richard Nota The ethics is about the people that oversee the design and programming […]

There are three different definitions of a black box, according to merriam webster: Definition of black box 1 :a usually complicated electronic device whose internal mechanism is usually […]

GANs, glorious GANs!

GANs, based on supervised learning and game theory, are just so darn elegant. The Grace Kelly of deep learning. Pitting the generator and the discriminator against each other (where the generator tries to fool the discriminator into classifying its output as a real sample) is genius in its simplicity. This report here gives a very good […]

Data Science Ethics: my initial thoughts

I had two main thoughts about this: self regulation by the data science profession, and data literacy. The promise of big data and artificial intelligence is at an all time high, but by no means at its peak. The availability of data to mine is growing exponentially. And yet the data science community is still relatively […]

Exploration of Tree Based Gradient Boosting Models to classify terrorism events as Suicide Attacks

Using Tree Based Gradient Boosting Models to classify terrorism events as Suicide Attacks Tracy Keys 13 June 2017 Background My team Gonzo at UTS used the Global Terrorism Database (GTD) to explore whether distinct features of terrorism events could predict the ABC’s online reaction to them. We did this through web scraping the ABC’s Twitter […]

Using topicmodels package for analysis of topics in texts

My vignette is about text mining and analysis, utilising the tm and topicmodels packages in R and Latent Dirichlet Allocation, to work out what the documents are written about without having to read them all! The vignette shows you how to create a Document-Term Matrix, then uses LDA to work out what key themes are […]

Is there a sexist data crisis? Hardly a crisis, but still important to resolve

In our session on Tuesday Simon K, as an aside, suggested we google “is there a sexist data crisis. “ I did, (here is a BBC article with that exact title http://www.bbc.com/news/magazine-36314061) but it got me thinking, this is hardly a crisis and hardly new. Women are underrepresented in many important things. For example, did […]
