Learning Machine Learning... with Kaggle

Published 09 Aug 2022

Somehow, in my one and a half years as a student studying a Bachelor of Data Science and Decisions, I’ve managed to learn close to nothing about what Machine Learning actually is (unless you count the one or two DataSoc workshops I’ve attended). So, because I’ve had a term off uni (and am in desperate need to upskill myself), I decided to check out Kaggle’s Introduction to Machine Learning course, and see what it’s all about.

Movie Review: AlphaGo documentary

Published 05 Apr 2022

Artificial intelligence (AI) often gets a bad rap in popular culture. In Hollywood films such as The Terminator and the Matrix, we see AI systems going rogue and taking over human, but in reality, the future of AI is less obtuse.

Published 14 Mar 2022

Honestly, the first year of university can be intimidating. So if you’re feeling a little overwhelmed (just as I did last year) - we’ve got you covered!

Looking back on my first year, I’d like to think I had a pretty good experience. But, looking back on it, there were also many things I would do differently.

Hey Apple, Take My Money

Published 28 Oct 2021

It was 19th October 2021 and I woke up at 4am. FOUR IN THE MORNING. Was it because I had a plane flight? Imagine having the opportunity to travel during these times. Maybe I had an assignment due the next day? In that case, I probably wouldn’t have been sleeping beforehand (jokes aside, please don’t leave it to the last minute). The reason was ridiculous: there was an Apple event. Exactly why do so many people love Apple products?

Did Somebody Say Crypto?

Published 21 Oct 2021

As a wannabe Data Scientist I love analysing marketing data and especially crypto currency market data. But in a world where Bitcoin’s price is as chaotic as WallStreetBets, how can we possibly get any sort of advantage over the casual trader who puts their life savings in Bitcoin in an effort to become the next Warren Buffet? So instead, let’s look away from technical analysis and towards market sentiment and become the next Jim Simmons.

Low Fertility Among Female Graduates

Published 26 Aug 2021

Australian women who are university graduates have fewer children than non-graduates. In most cases this appears to be the result of circumstantial pressures not preference. Long years of study fill the most fertile years of women students and new graduates need further time to establish their careers. The chance of medical infertility increases with age so, for some, this means that childbearing is not postponed but ruled out.

Natural Language Processing: The Love Child of Machine Learning and Linguistics

Published 09 Sep 2020

Languages are, at their basis, systems for organizing smaller, less meaningful components into larger, more meaningful components. A string of sounds is a word, a string of words makes a sentences, a series of sentences becomes a paragraph, and enough paragraphs make a book, an essay, a speech, or whatever other form one might envision. Language – text, speech, tweets and so on – is one of the most common forms of data we are exposed to and produce. It’s one of the primary forms of human communication – but while we understand each other perfectly fine, is it possible for the computer to understand, and even participate, as well?

The Laborious Process of Pinning Down Data Science: A Tragedy in Five Acts

Data Science and Data Analytics: What’s the Difference?

Published 18 Jul 2020
