Matlab Code

Matlab File Exchange

My Matlab code comprises two pedagogical software demos - one for linear SVMs and one for Adaboost. The Adaboost demo was developed as part of a lecture that I delivered for an MSc Machine Learning course (Machine Learning and Data Mining).

There is also a progress bar tool that I wrote. It was chosen as the Matlab File Exchange "Pick of the Week"

No-Free-Lunch Theorem Talk

I gave this talk to the Machester MLO group. It gives an introduction to No-Free-Lunch theorems, shows how they apply to Bayesian Inference and Structural Risk Minimisation, and then describes a relationship with epistemic philosophy.

I have also presented a similar talk to the Random Walks on Physics lecture series in the University of Manchester School of Physics and Astronomy. In this version of the talk, I omitted discussion of SRM, and instead presented some instances of NFL-like issues in Aumann's Agreement Theorem, Compression and Regression.

Boosting Lecture

I delivered this lecture on Adaboost to MSc students on the Machine Learning and Data Mining course. It introduces the algorithm and delves into one of its facinating theoretical properties.
