I'm a postdoc at LIUM in France, working in Machine Learning (statistical machine translation), although my thesis was on mathematical analysis of Evolutionary Algorithms (EAs), therefore my skills revolve around probability, Markov chains, calc/analysis, asymptotics and a bit of combinatorics.

I'm here mostly to learn and improve my skills, so please don't expect much rigor or proficiency from me.

This is my Academia profile if you are interested in my work for some reason.

comment Easy way to compute $Pr[\sum_{i=1}^t X_i \geq z]$
partial sum of rows in the Pascal triangle doesn't have a closed form, but you can either 1) use an approximation or 2) use the Central limit theorem. For large $t$ it gives a good approximation.
