Hi, I’m Firas Abuzaid; thanks for visiting my website. I’m a 4th-year Ph.D. student in Computer Science at Stanford University, co-advised by Matei Zaharia and Peter Bailis.

As a member of the FutureData Systems Group and the Stanford DAWN Project, I focus on the intersection of systems and machine learning: how to take high-level machine learning tasks and build software systems to improve the efficiency of these tasks without sacrificing their accuracy.

I spent the first year of my Ph.D. at MIT CSAIL, working under Matei Zaharia and Sam Madden as part of the MIT DB group.

Prior to MIT, I was at Stanford, where I completed my B.S. and M.S. in Computer Science. I worked with Chris Ré on database systems and machine learning systems.

You can check out my CV here.

Latest Work

MacroBase SQL

DIFF, a new SQL operator, provides a generalizable interface for finding explanations in large-scale datasets. Our implementation of DIFF in MacroBase SQL (a fork of MacroBase) outperforms other state-of-the-art explanation engines by up to an order of magnitude.

MacroBase

MacroBase is a new a data analytics engine that prioritizes end-user attention in high-volume fast data streams. MacroBase enables efficient, accurate, and modular analyses that highlight and aggregate important and unusual behavior, acting as a search engine for fast data. MacroBase is able to deliver order-of-magnitude speedups over alternatives by optimizing the combination of explanation (i.e., feature selection) and classification tasks and by leveraging a new reservoir sampler and heavy-hitters sketch specialized for fast data streams. As a result, MacroBase delivers accurate results at speeds of up to 2M events per second per query on a single core. The system has delivered meaningful results in production, including at a telematics company monitoring hundreds of thousands of vehicles.
