This is an old revision of the document!



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.

The infinite MNIST dataset

Why settle for 60000 MNIST training examples when you can have one trillion? The MNIST8M dataset was generated using the elastic deformation code originally written for (Loosli, Canu, and Bottou, 2007). Unfortunately the original MNIST8M files were accidentally deleted from the NEC servers a couple weeks ago. Instead of regenerating the files, I have repackaged the generation code in a convenient form.

Explore/Exploit = Correlation/Causation!

advertiserloop.jpg Our paper“Counterfactual Reasoning and Learning Systems: The Example of Computational Advertising” has appeared in JMLR. This paper takes the example of ad placement to illustrate how one can leverage causal inference to understand the behavior of complex learning systems interacting with their environment.
