About

Hi, I’m Bryan Feeney, studying for a PhD machine learning here in the statistics department at UCL, which previously worked with another Irishman, William Gosset, better known as the “student” who invented the t-distribution – hence the name.

Mostly I’ll be writing things here to clarify them in my own mind, so I should probably say right now there’s no guarantee that any of it will be readable, consistent or even correct.

This may also  involve some sums…

r_{nk} = \frac {\rho_{nk}}{\sum_j \rho_{nj}}
