I am a research scientist with broad interests in practical and theoretical machine learning. My work on large scale learning and stochastic gradient algorithms has received attention in the recent years. I am also known for the DjVu document compression system. I joined Facebook AI Research in March 2015.

Nips 2013

tahoe.jpg Nips just took place near Lake Tahoe. Many people have written how things are changing in machine learning. There also were many interesting papers and invited talks. Thanks to the program chairs Max and Zoubin for producing this exciting conference program. Thanks to the workshop chairs Rich Caruana and Gunnar Rätsch for the stimulating workshops. Thanks to Terry Sejnowsky for creating NIPS, and special thanks to Mary-Ellen Perry without whom nothing would happen.

Counterfactual Reasoning and Learning Systems

The report “Counterfactual Reasoning and Learning Systems” shows how to leverage causal inference to understand the behavior of complex learning systems interacting with their environment and predict the consequences of changes to the system. Such predictions allow both humans and algorithms to select changes that improve both the short-term and long-term performance of such systems. This work is illustrated by experiments carried out on the ad placement system associated with the Bing search engine.

SGD-2.0 released

Announcing version 2.0 of my Stochastic Gradient Descent package. This release provides implementations of the Stochastic Gradient Descent and Averaged Stochastic Gradient Descent algorithms for Linear SVMs and CRFs. The latter sometimes shows vastly superior performance. See the SGD package pages for details.

Natural Language Processing from Scratch

Ronan's masterpiece, "Natural Language Processing (Almost) from Scratch", has been published in JMLR. This paper describes how to use a unified neural network architecture to solve a collection of natural language processing tasks with near state-of-the-art accuracies and ridiculously fast processing speed. A couple thousand lines of C code processes english sentence at more than 10000 words per second and outputs part-of-speech tags, named entity tags, chunk boundaries, semantic role labeling tags, and, in the latest version, syntactic parse trees.
