“I was Steve's advisor at the Harvard Kennedy School, though he did not need much advising. He has one of the quickest and most imaginative minds ever to grace this place. He had then, and certainly has now, a remarkable ability to blend (and create) cutting-edge technologies with a creative and contrarian approach to the social sciences. I predicted then, and believe now, that Steve Purpura will be among the most important scholars of his generation.”

The latest perk I’m hearing for AI startups is that they own their own Autel fast DC charger for employee use when they’re at the office.

Statistically adaptive learning for a general class of cost functions (SA L-BFGS)
arXiV
We present a system that enables rapid model experimentation for tera-scale machine learning with trillions of non-zero features, billions of training examples, and millions of parameters. Our contribution to the literature is a new method (SA L-BFGS) for changing batch L-BFGS to perform in near real-time by using statistical tools to balance the contributions of previous weights, old training examples, and new training examples to achieve fast convergence with few iterations. The result is, to…
We present a system that enables rapid model experimentation for tera-scale machine learning with trillions of non-zero features, billions of training examples, and millions of parameters. Our contribution to the literature is a new method (SA L-BFGS) for changing batch L-BFGS to perform in near real-time by using statistical tools to balance the contributions of previous weights, old training examples, and new training examples to achieve fast convergence with few iterations. The result is, to our knowledge, the most scalable and flexible linear learning system reported in the literature, beating standard practice with the current best system (Vowpal Wabbit and AllReduce). Using the KDD Cup 2012 data set from Tencent, Inc. we provide experimental results to verify the performance of this method.

Managing state information across communication sessions between a client and a server using a stateless protocol
Issued US US 2004/0181598 A1
This patent reinvented web cookies to allow browser applications to maintain authentication information on web browsers that had disabled cookies. It allowed for behavioral tracking of web site users even when their browser cookies were disabled. I originally invented this technology as part of a dialogue with 13 state attorneys general over the effectiveness of laws restricting cookie implementation in the browser.
