Fionn Delahunty

Irish man currently living in Sweden.

I’m a bit young to have a life vision, but at the moment I spent most of professional time harnessing the powers of data science to explore different aspects of human behaviour and psychology. I work on detecting depression using machine learning, exploring patterns and trends in online communities and various other projects.

In my spare time, I love exploring the outdoors. From sailing, to climbing and everything in between. I worked for several years as professional sailing instructor, balancing safety of participants with enjoyment and keeping a business afloat. As much as I love the outdoors, it’s nice to sit down behind a desk and not be soaking wet!

What I Do

Machine Learning

More than just linear regression, comfortable in building prediction systems employing either supervised or unsupervised data techniques. From logistical regression, to KNNs .

Research

Research is all about asking questions, and answering them using empirical evidence. It can be tough, but rewarding and I enjoy doing it.

Psychology

I have a first class honors BA in Psychology, this kindled my love of research and human behaviour.

Data Science

A term that only came into existance 15 years ago, I'm due to complete a MSc in Applied Data Science at the end of this year.

First Insights on a Passive Major Depressive Disorder Prediction System with Incorporated Conversational Chatbot

Fionn Delahunty, Ian D. Wood , Mihael Arcan

Abstract: Almost 50% of cases of major depressive disorder go undiagnosed. In this paper, we propose a passive diagnostic system that combines the areas of clinical psychology, machine learning and conversational dialogue systems. We have trained a dialogue system, powered by sequence-to-sequence neural networks that can have a real-time conversation with individuals. In tandem, we have developed specific machine learning classifiers that monitor the conversation and predict the presence or absence of certain crucial depression symptoms. This would facilitate real-time instant crisis support for those suffering from depression. Our evaluation metrics have suggested this could be a positive future direction of research in both developing more human like chatbots and identifying depression in written text. We hope this work may additionally have practical implications in the area of crisis support services for mental health organisations.

Using clickers to predict students final courses grades, a machine learning approach

Fionn Delahunty, Alexander Schliep

Abstract: In this short report, we expand on the existing work exploring the relationship between in class clicker scores and final coures grades. We develop a random forest classifier to predict which grade band a student will fall into based on their scores. We achieve high accuracy metrics in the evaluation stage.

Assessing the effects of internet-related drug urges on inhibition using an anti-saccade task

Fionn Delahunty, Denis O'hora

Abstract: Assessing the effects of internet-related urges on inhibition using an anti-saccade task Background: The average adult spends two thirds of waking day online; many researchers propose that this excess internet usage is driven by some form of behavioural addiction. One feature of addictions, according to the Tiffany cognitive urge model, is the presence of urges (i.e., craving) to engage in the behaviour that are difficult to ignore. The current study attempted to establish whether urges occurs for internet usage and test whether such urges interferes with inhibition processes.
