Ilya Razenshteyn

GENERAL INFORMATION

Since September 2012 I am a graduate student at MIT Computer Science and Artificial Intelligence Laboratory. I am privileged to be advised by Piotr Indyk. I graduated in June 2012 from Moscow State University, where my advisors were great Maxim Babenko and Sasha Shen.

Watch some of my talks:

“Optimal Hashing-based Time-Space Trade-offs for Approximate Near Neighbors” (CMU Theory Lunch)
“Sketching and Embedding are Equivalent for Norms” (TCS+)
“Locality-Sensitive Hashing and Beyond” (Microsoft Research)

We have released FALCONN: a highly optimized C++ library (with a Python wrapper) for similarity search based on LSH.

DBLP and Google Scholar

I do Theoretical Computer Science. My research interests include: similarity search, sketching, metric embeddings, high-dimensional geometry, streaming algorithms, compressed sensing, combinatorial optimization.

My wife does Theory as well!
