11:11 AM | Hardware Based Stochastic Gradient Descent
  Starting at 52 minutes and 10 seconds of this video, Ali Rahimi explains how one can use a noisy evaluation of the gradient in a gradient descent algorithm in order to minimize a convex function (most relaxations featured in current Advanced Matrix Factorization techniques and some instances of Compressive Sensing fall in that category). The interesting part of this is that the noise comes from the errors made by the, now stochastic, Floating Point Unit.  From the paper […]

6:14 PM | Isn’t Hurting Ourselves Enough?
We alcoholics hurt people. Over and over again. We do terrible things and we victimize people over and over again. We take advantage. We behave boorishly, vilely. And we don’t seem to care about the damage we do. After all, if we cared, why would we keep repeating it? A friend asked me recently why […]

4:49 PM | To Keep Moving is To Live
We’ve all seen the scenario in our high school biology textbooks. A single population of fish shares a large Pond. But then something drastic happens in the landscape. Perhaps a drought occurs, and the large Pond partially dries up to leave two smaller ponds separated from each other by a hill or expanse of higher, dry land. If this separation lasts long enough, combining the fish from pond A and pond B produces an interesting effect – the fish can... Read more

RANDOMIZED ALGORITHMS FOR LARGE-SCALE STRONGLY OVER-DETERMINED LINEAR REGRESSION PROBLEMSXiangrui MengIn the era of big data, distributed systems built on top of clusters of commodity hardware provide cheap and reliable storage and scalable data processing. With cheap storage, instead of storing only currently relevant data, most people choose to store data as much as possible, expecting that its value can be extracted later. In this way, exabytes (1018) of data are being created on a daily […]
