Welcome to another UNSW DataSoc blog! In this post, we are excited to present the intriguing findings of our internal sleep study. With the participation of 22 unique students, we delved into the sleep habits and patterns of our society members. The study involved the collection of sleep data for all 7 days of the week using a digital survey, resulting in a wealth of information that sheds light on the sleep behaviours of our diverse community. 🌟🌙

“F*** it, I’m going to ChatGPT the answer”
Over the last term, I’ve said this phrase countless times in a last ditch effort to scrape any form of marks to answer my quizzes or assignments.
Since it’s launch in November 2022, ChatGPT has taken the world by storm - becoming fastest-growing consumer app in internet history by reaching 100 million users within two months. Of course, this rise does not come without controversy, including:
Where OpenAI’s current CEO confirmed numerous data breaches that were caused by a vulnerability in the code’s open-source library.
we had a significant issue in ChatGPT due to a bug in an open source library, for which a fix has now been released and we have just finished validating.— Sam Altman (@sama) March 22, 2023
a small percentage of users were able to see the titles of other users’ conversation history.
we feel awful about this.
This data breach is reported to have exposed another active user’s first and last name, email address, payment address, credit card type and the last four digits (only) of a credit card number, and credit card expiration date.
Read more on this data breach here.
“the mass collection and storage of personal data for the purpose of ‘training’ the algorithms underlying the operation of the platform”.
“exposes minors to absolutely unsuitable answers compared to their degree of development and awareness”.
With Italy making headlines as the first Western country to block ChatGPT, a precedent has now been set and the European Union has been reported to work on the world’s first artificial intelligence legislation.
Aside from the data and privacy issues that stem from generative AI, controversy has also formed for education - with UNSW’s students being caught for academic misconduct for use of generative AI.
Following this, all UNSW students were emailed a statement regarding Turnitin’s new AI detection tool:
“While the technology changes, our values around academic integrity do not. Your work must be your own and where the use of AI tools like ChatGPT have been permitted by your course convener, they must be properly credited, and your submissions must be substantially your own work. In cases where the use of AI has been prohibited, please respect this and be aware that where unauthorised use is detected, penalties will apply.”
In the workplace, reception towards usage of generative AI has been all over the spectrum - where firms such as Samsung, Amazon, Bank of America, and JP Morgan outright banned the use of ChatGPT, voicing concerns regarding copyright infringement and disclosure of data.
On the other hand, firms like Citadel, are currently negotiating an enterprise-wide license for the tool. Similarly, a case can be made for automating menial office tasks - where generative AI points to a future where many of the boring parts of white-collar life are easily completed.
On the other side of the coin, Goldman Sachs anticipates that 300 million jobs will be displaced by AI as the aforementioned low-skilled tasks and jobs become automated. However, it is likely that jobs which require more ‘complexity’ and ‘creativity’ will be safe from the jaws of automation.
For more information on how generative AI will change the workplace, read here.
TLDR: ChatGPT is revolutionising the workplace, but doesn’t come without its drawbacks, including privacy breaches, and an increase in academic misconduct.

Whether you’ve never entered the casino, or are an experienced or avid gambler. You have likely heard the term “The house always wins”. In my interest of casino games after winning a whopping $35 playing blackjack, I got curious to know how lucky I truly got in order to turn a profit whilst gambling in a casino. Today we will be exploring the statistics behind the most popular casino games and why the catch phrase “The house always wins” holds true.

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.

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. Greg Kohs’ 2017 documentary, AlphaGo, offers a fantastic introduction into the world of AI.

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. So, I wanted to see if some people at DataSoc felt the same way, and asked them about the experiences they had in first year - both the good, and the bad. Here are the top 5 tips I was able to come up with!

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?

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.

Every statistics course will introduce at some point the big statistics taboo: confusing correlation and causation. With the rise of data as a driving force in our world, the joke has become famous. Correlation does not imply causation. But what does this actually mean?

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.

We all thought that pursuing a degree within computer science would be safe. As we enter a digital era driven by the technology advancements worldwide, an alarming number of occupations are becoming outdated, automated or just rendered redundant. Surely a career in the STEM-related field would be immune to unemployment? But now we’ve gone to the extent of developing something that will write code for us. Could this be the beginning of how “artificial intelligence could spell the end of the human race”?

Have you ever considered getting started with deep learning but instead got frustrated by the steep learning curve and huge body of knowledge required to even start hacking up a simple “hello world” program in Pytorch? Thanks to like minded individuals, fastai was developed to provide high-level api access, making the creation of state of the art deep neural networks as easy as a couple of lines of code.

As Covid-19 continues to remain in the zeitgeist (hello to everyone reading this in a post-covid world), the rising number of charts depicting infections and deaths over time continues to flood the media.
Yet, I find that charts and single statistics don’t bring to justice the magnitude and scale of disease transmission. More specifically, how can we better visualise the spread and scale of diseases?

We all know about how command F (or crtl+F) allows you to instantly search for a particular word within thousands of lines in a file or webpage. But what if we wanted to search with more parameters on the results? Is there a more powerful alternative to find matches straight from our terminal? The answer is YES – and it’s Regex!

Data visualisation has come a long way since the era of making column and bar charts on excel. New visualisation tools like Tableau and Google Charts offer a user-friendly solution that caters to a range of users of varying skills. Translating bland tables of data into graphical modules of data and information has helped accelerate the trend of ‘data-driven’ decisions across organisations.

One of the most popular applications of machine learning or data science in solving real-world problems is building meaningful models that could not only explain the variation in the target variable but also provide reliable predictions for unseen observations. But what if our model has high error metrics, what can we do to mitigate the situation?

Quantitative Analysis is an ever growing field in finance that draws on Data Science skills to create trading strategies. In fact, the field is often so difficult that institutions often call for Math PhDs to develop their strategies.
But what if we could subvert the intracies of developing complex models and instead trade stocks on the sentiment of the crowd.

Given their predictive accuracy and ease of creation, models trained on massive amounts of data are everywhere, and are increasingly used to inform important decisions. How much your insurance premium costs, whether you get a home loan or how much your next plane ticket costs are reduced to mathematical functions. They input your personal data as parameters and spit out a final value which guides the decision.

As AIs become increasingly powerful, they become more and more able to imitate, and generate human speech. Last time, I went on a long ramble on the fictional hypotheses about the societal, moral and philosophical questions that might eventually arise around AI. This time, I thought I might put the fictional to the test – by personally engaging with an AI myself.

Since the advent of the technological age, as constant scientific breakthrough became the norm, the unknown future of a world changing more rapidly than ever more has captured the minds of countless artists, poets and writers. The future could no longer reliably be considered the mere extension of the past. Old knowledge was no longer secure in its vault. Anything could change at any moment. Could humankind journey to the centre of the earth? The bottom of the sea? The surface of the moon and the outer rim of space?

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?

“Numbers don’t lie…but people do.”
As data-literate individuals in a data-drenched world, we need to keep our wits about us and retain our critical thinking when people present us with studies and visualisations that seem to have all the answers. Here’s why, with some examples.

Societies are a polarising subject among students - depending on who you ask, you may hear that “You have to participate in a uni society for your career!” or “Societies are toxic and cult-like”. So what’s the big deal? What are societies, why should you get involved, and why shouldn’t you get involved?
In other words, Why bother?”

As a society whose name and purpose revolves around the field of data science, it seems fitting to take a step back and examine data science itself. What constitutes this degree and this career? It might be ‘the sexiest job of the 20th century’, but sexy is hardly precise or specific, especially when the subject is an academic field rather than the aesthetic appreciation of the human (or non-human) body.

More often than not, anything to do with data processing gets grouped under the umbrella term of data science. This can lead to bewilderment when terms such as data analytics come up, which, while sometimes used interchangeably with data science is in actuality reference an interconnected but distinct field. Both areas ripe with opportunity and worthy of study, it is important and useful to distinguish between them, and the differing skillsets they require and roles the play in the industry.
