Sequential Monte Carlo 2015 workshop

An announcement for the SMC 2015 workshop: Sequential Monte Carlo methods (also known as particle filters) have revolutionized the on-line and off-line analysis of data in fields as diverse as target tracking, computer vision, financial modelling, brain imagery, or population ecology.

An uninformative end state

This chart cited by ZeroHedge feels like a parody. It's a bar chart that doesn't utilize the length of bars. It's a dot plot that doesn't utilize the position of dots. The range of commute times (between city centers and...

How a fraud detection algorithm conspired to ruin my recent trip

October 30, 2014
By

I have been traveling quite a bit lately, and last week, I went to Rome for a few days, and spent time at the KDIR conference. Rome is one of my favorite destinations and apart from the architecture and museums, and the restaurants, I also enjoy shopping there.

Bangalore workshop [ಬೆಂಗಳೂರು ಕಾರ್ಯಾಗಾರ]

Second day at the Indo-French Centre for Applied Mathematics and the workshop. Maybe not the most exciting day in terms of talks (as I missed the first two plenary sessions by (a) oversleeping and (b) running across the campus!).

implementing reproducible research [short book review]

As promised, I got back to this book, Implementing reproducible research (after the pigeons had their say). I looked at it this morning while monitoring my students taking their last-chance R exam (definitely last chance as my undergraduate R course is not reconoduced next year).
