This a personal web page/blog of Leonid Boytsov. He currently works as a research scientist at M*Modal.
Leonid was a graduate research assistant (aka PhD student) at the Language Technologies Institute at Carnegie Mellon University (under the supervision of Professor Eric Nyberg). His dissertation topic is "Efficient and Accurate NonMetric kNN Search with Applications to Text Matching". He was assisting in teaching the following courses & seminars: Algorithms for NLP (11711) in 2013, Software Engineering I (11791) and Data Science Seminar (11631) in 2014.
An important byproduct of Leonid's research is an efficient and flexible library for kNN search codenamed NMSLIB created in collaboration with several other folks. Feel free to check our code on GitHub.
Leonid also coauthored an extremely efficient algorithm for lightweight compression of sorted integer numbers. We show that this algorithm can decompress at the speed of reading from memory. You can find software on GitHub. This software grew out of a nowpopular library FastPFor. FastPFor has Python bindings.
Leonid likes collecting material related to search technologies and other AIrelated topics (e.g., algorithms, software, interesting papers, and even historical anecdotes). Note that his opinions and views do not necessarily represent opinions of his employer, his dissertation advisor, or the Language Technologies Institute.
