Reboot: Accelerating Deep Neural Nets by Reducing Image Resolution

A few months ago, I blogged about how to reduce AlexNet image resolution without giving up much ImageNet accuracy. I’m not quite sure what I did wrong, but I’m not able to reproduce those results. I’m sorry for leading you down the wrong path, and thanks to the 10 people who wrote me with questions […]

Accelerating AlexNet by Reducing Image Resolution

Running AlexNet in Caffe with 128×128 instead of 256×256 images, we observed a 5.4x speedup and a

Scrambled Eggs

Making scrambled eggs is as easy as “scramble some eggs and cook them,” right? Well, sort of. There are a lot of subtle choices!

Best Computer Science Interview Question Ever

While perusing the blog of Chris Sells of Microsoft, I came across the best interview question I’ve ever seen: I walked into my first technical interview at Microsoft, and before I could say anything, the woman says, You’re in an 8×8 stone corridor. I blink and sit down. Interviewer: The prince of darkness appears before […]

Highlights From Visiting Google

This week, with a group of University of Illinois computer science students, I visited Google’s Chicago office. The Chicago location was founded primarily to house Chicago-based engineering superstars Brian “Fitz” Fitzpatrick and Ben Collins-Sussman, both of whom joined us at Illinois for the ACM Reflections|Projections Conference last fall. Today, the University of Illinois group was […]
