For AICan 2024: Annual Meeting for the pan-Canadian AI Strategy and the CIFAR AI Chairs; In Banff. You can’t help but know when you come to a place like this, and a view like this, that you are somewhere special. … Continue reading Visions of AI: Building our Sociotechnical Future
Keynote for the 40th International Conference on Machine Learning (ICML 2023). Links to the Video, and Slides (pdf, 30MB). Abstract: This talk talk has a single objective: to advocate for machine learning infused with social purpose. Social purpose here is … Continue reading Machine Learning with Social Purpose
Was so excited to get this opportunity to talk about pain and learning at the NeurIPS2020 Workshop on Biological and Artificial RL. This is the text of the talk. Collaboration with Daniel Ott. 🎞Watch the video here; 🖥 slides here; 📜 paper … Continue reading Pain and Machine Learning

It will not reveal a clever manipulation of a probability or an integral or a derivative, or produce a code … Continue reading Machine Learning Trick of the Day (8): Instrumental Thinking
· Read in · 1481 words · All posts in series · [dropcap]A[/dropcap] probability on its own is often an uninteresting thing. But when we can compare probabilities, that is when their full splendour is revealed. By comparing probabilities we … Continue reading Machine Learning Trick of the Day (7): Density Ratio Trick

This is what, for me at least, makes machine learning research such a rewarding and exciting area to work in. We … Continue reading Cognitive Machine Learning: Prologue
· Read in · Our first encounters with probability are often through a collection of simple games. The games of probability are played with coins, dice, cards, balls and urns, and sticks and strings. Using these games, we built an intuition that … Continue reading Machine Learning Trick of the Day (6): Tricks with Sticks
Machine learning involves manipulating probabilities. These probabilities are most often represented as normalised-probabilities or as log-probabilities. An ability to shrewdly alternate between these two representations is a vital step towards strengthening the probabilistic dexterity we need to solve modern machine learning problems. Today's trick, the log derivative trick, helps … Continue reading Machine Learning Trick of the Day (5): Log Derivative Trick
Our ability to rewrite statistical problems in an equivalent but different form, to reparameterise them, is one of the most general-purpose tools we have in mathematical statistics. We used reparameterisation in all the tricks we explored in this series so far: trick 1 re-expressed a … Continue reading Machine Learning Trick of the Day (4): Reparameterisation Tricks
Hutchinson's estimator [cite key='hutchinson1990stochastic'] is a simple way to obtain a stochastic estimate of the trace of a matrix. This is a simple trick that uses randomisation to transform the algebraic problem of computing the trace into the statistical problem of … Continue reading Machine Learning Trick of the Day (3): Hutchinson's Trick
