Unsub grant text: A Coordination Center for Training in Biomedical Data Science

" Just as I was moving to UC Davis, a funding call for a trainingcoordination center came out. I got partway down the path of applying for it beforerealizing that I was overwhelmed with the move, but I did generatesome text that I thought was OK. Here it is! The increasing velocity, variety, and volume of data generated inbi... View More

Holdout cross-validation generator

" Cross-validation iterators in scikit-learn are simply generator objects, that is, Python objects that implement the iter method and that for each call to this method return (or more precisely, yield ) the indices or a boolean mask for the train and test set. Hence, implementing new cross-validation iterators that behav... View More

Attributing changes to numerator and denominator

" This afternoon I helped someone debug a financial spreadsheet. One of the reasons spreadsheets can be so frustrating to work with is that assumptions are hard to see. You have to click on cells one at a time to find formulas, then decode cell coordinates into their meanings. The root problem turned out to be an assumption that ... View More

Last digit of largest known prime

" In my previous post , we looked at the largest known prime, P = 2 57885161 1, and how many digits it has in various bases.This post looks at how to findthe last digit of P in base b . We assume b < P . (If b = P then the last digit is 0, and if b > P the last digit is P .) If ... View More
