  • I'm an associate professor in the Stanford AI Lab (SAIL), the center for research on foundation models (CRFM), and the Machine Learning Group (bio). Our lab works on the foundations of the next generation of AI systems.
    • On the AI side, I am fascinated by how we can learn from increasingly weak forms of supervision, the basis of new architectures, the role of data, and by the mathematical foundations of such techniques.
    • On the systems side, I am broadly interested in how machine learning is changing how we build software and hardware. I'm particularly excited when we can blend AI and systems, e.g,. Snorkel, Overton (YouTube), SambaNova, or Together.
    Our work is inspired by the observation that data is central to these systems, and so data management principles (re-imagined) play a starring role in our work. This sounds like Silicon Valley nonsense, but oddly enough, these ideas get used due to amazing students and collaborations with Google ads, YouTube, Apple, and more.

    While we're very proud of our research ideas and their impact, the lab's real goal is to help students become professors, entrepreneurs, and researchers. To that end, over a dozen members of our group have started their own professorships. With students and collaborators, I've been fortunate enough to cofound a number of companies and a venture firm. For transparency, I try to list companies I advise or invest in here and our research sponsors here. My students run the ML Sys Podcast.

We are working on two broad topics:
  • (1) DeepDive is a new type of system to extract value from dark data. Like dark matter, dark data is the great mass of data buried in text, tables, figures, and images, which lacks structure and so is essentially unprocessable by existing data systems. DeepDive's most popular use case is to transform the dark data of web pages, pdfs, and other databases into rich SQL-style databases. In turn, these databases can be used to support both SQL-style and predictive analytics. Recently, some DeepDive-based applications have exceeded the quality of human volunteer annotators in both precision and recall for complex scientific articles. Data produced by DeepDive is used by several law enforcement agencies and NGOs to fight human trafficking. The technical core of DeepDive is an engine that combines extraction, integration, and prediction into a single engine with probabilistic inference as its core operation. A one pager with key design highlights is here. PaleoDeepDive is featured in the July 2015 issue of Nature.

    • DeepDive is our attempt to understand a new type of database system. Our new approach can be summarized as follows: the data, the output of various tools, the input from users — including the program the developer writes — are observations from which the system statistically infers the answer. This view is a radical departure from traditional data processing systems, which assume that the data is one-hundred percent correct. A key problem in DeepDive is that the system needs to consider many possible interpretations for each data item. In turn, we need to explore a huge number of combinations during probabilistic inference, which is one of the core technical challenges.
    Our goal is to acquire more sources of data for DeepDive to understand more deeply to change the way that science and industry operate.
  • (2) Fundamentals of Data Processing. Almost all data processing systems have their intellectual roots in first order logic. The most computationally expensive (and most interesting) operation in such systems is the relational join. Recently, I helped discover the first join algorithm with optimal worst-case running time. This result uses a novel connection between logic, combinatorics, and geometry. We are using this connection to develop new attacks on classical problems in listing patterns in graphs and in statistical inference. Two threads have emerged:
      • The first theme is that these new worst-case-optimal algorithms are fundamentally different from the algorithms used in (most of) today's data processing systems. Although our algorithm is optimal in the worst case, commercial relational database engines have been tuned to work well on real data sets by smart people for about four decades. And so a difficult question is how does one translate these insights into real data processing systems?
      • The second theme is that we may need new techniques to get theoretical results strong enough to guide practice. As a result, I've started thinking about "beyond worst-case analysis" and things like conditioning for combinatorial problems to hopefully build theory that can inform practice to a greater extent. The first papers have just been posted.
    • Demos, Examples, and Papers.
      • Worst-case Optimal Joins. We have posted a survey for SIGMOD record about recent advances in join algorithms. Our goal is to give a high-level view of the results for practitioners and applied researchers. We also managed to simplify the arguments. A full version of our join algorithm with worst-case optimal running time is here. The LogicBlox guys have their own commercial worst-case optimal algorithm. Our new system, EmptyHeaded is based on this theory.
      • Beyond Worst-case Joins. This work is our attempt to go beyond worst-case analysis for join algorithms. We (with Dung Nguyen) develop a new algorithm that we call Minesweeper based on these ideas. The main theoretical idea is to formalize the amount of work any algorithm spends certifying (using a set of propositional statements) that the output set is complete (and not, say, a proper subset). We call this set of propositions the certificate. We manage to establish a dichotomy theorem for this stronger notion of complexity: if a query is what Ron Fagin calls beta-acyclic, then Minesweeper runs in time linear in the certificate; if a query is beta-cyclic than on some instance any algorithm takes time that is super linear in the certificate. The results get sharper and more fun.
      • Almost to one algorithm to rule them all? We have a much better description of beyond worst-case optimality with a resolution framework and a host of new results for different indexing strategies. This paper supercedes many of the results in Minesweeper and in a much nicer way!. We also hope to connect more of geometry and resolution... but we'll see!
      • A first part of our attack on conditioning for combinatorial problems is in NIPS and on Arxiv.
      • It is not difficult to get me interested in a theory problem. Ask around the Infolab if you don't believe me.
    Our goal is to understand the fundamentals of data processing systems.
