Tim Leathart


just another machine learning enthusiast

I'm a PhD candidate at the University of Waikato, as part of the Machine Learning group. I also work part time as a data scientist at Xero. My research mainly focuses on nested dichotomies, a technique for recursively splitting the set of labels for a dataset in a tree structure. Recently, I have also been working on tree-based approaches to probability calibration. I started working on my PhD in 2015, after completing a Bachelor of Computing and Mathematical Sciences (first class honours) at the University of Waikato. My supervisors are Eibe Frank, Bernhard Pfahringer and Geoff Holmes.

I received a Doctoral Scholarship, but I am currently being funded through a Marsden grant. I have also been awarded an Undergraduate Computer Science scholarship, and two Deans' Awards for Excellence as an undergrad.

Outside of my research, I love music & films, travel, cooking and staying active. I love hiking and playing sports, and I try to get outdoors as often as I can. I currently play ultimate frisbee for the club Hammertron, the main club based in Hamilton.
