Reducing AI Bias Using Truncated Statistics
An emergent threat to the practical use of machine learning is the presence of bias in the data used to train models. Biased training data can result in models which make incorrect or disproportionately correct decisions, or that reinforce the injustices reflected in their training data. For example, recent works have shown that semantics derived automatically from text corpora contain human biases, and found that the accuracy of face and gender recognition systems are systematically lower for people of color and women. While the root causes of AI bias are difficult to pin down, a common cause of bias is the violation of the pervasive assumption that the data used to train models are unbiased samples of an underlying “test distribution,” which represents the conditions that the trained model will encounter in the future.  Overcoming the bias introduced by the discrepancy between train and test distributions has been the focus of a long line of research in truncated Statistics. We provide computationally and statistically efficient algorithms for truncated density estimation and truncated linear, logistic and probit regression in high dimensions, through a general, practical framework based on Stochastic Gradient Descent.  We illustrate the efficacy of our framework through several experiments.

Bio: David Eisenbud served as Director of MSRI from 1997 to 2007, and began a new term in 2013. He received his PhD in mathematics in 1970 at the University of Chicago under Saunders MacLane and Chris Robson, and was on the faculty at Brandeis University before coming to Berkeley, where he became Professor of Mathematics in 1997. He served from 2009 to 2011 as Director for Mathematics and the Physical Sciences at the Simons Foundation, and is currently on the Board of Directors of the Foundation. He has been a visiting professor at Harvard, Bonn, and Paris. Eisenbud’s mathematical interests range widely over commutative and non-commutative algebra, algebraic geometry, topology, and computer methods.
Eisenbud is Chair of the Editorial Board of the Algebra and Number Theory journal, which he helped found in 2006, and serves on the Board of the Journal of Software for Algebra and Geometry, as well as Springer-Verlag’s book series Algorithms and Computation in Mathematics.
Eisenbud was President of the American Mathematical Society from 2003 to 2005. He is a Director of Math for America, a foundation devoted to improving mathematics teaching. He has been a member of the Board of Mathematical Sciences and their Applications of the National Research Council, and is a member of the U.S. National Committee of the International Mathematical Union. In 2006, Eisenbud was elected a Fellow of the American Academy of Arts and Sciences.

  1. 1. Collaborative Research at the Frontiers David Eisenbud Director MSRI
  2. 2. 17 GAUSS WAY, BERKELEY, CALIFORNIA WWW.MSRI.ORG Collaborative research at the frontiers
  3. 3. What Distinguishes MSRI? Exceptional Breadth of Scientific Activity • MSRI programs span every aspect of fundamental mathematics and many applications resulting from the latest discoveries of advanced research • MSRI is a center where new fields are born (MSRI was among the first to recognize Random Matrix Theory as a significant field), and where classical topics such as symplectic geometry can have a major revival. • We connect mathematicians and math educators through workshops on “Critical Issues in K-12 Education” 3
  4. 4. What Distinguishes MSRI? A place where young talent flourishes • MSRI is a place where young talent is mentored, where careers are developed, and where underrepresented groups are empowered • Summer Graduate Schools include strong contact between students and leaders • Groundbreaking, sustained programs empowering women and minorities (MSRI- UP, SWiM, ADJOINT, Connections workshops...) 4
  5. 5. What Distinguishes MSRI? MSRI is supported by the whole Math Community • A network of 110 “Academic Sponsor” institutions – from the US and abroad share in governance • Impeccable advisors such as Dusa MacDuff, Fields Medalists Charlie Fefferman, Andrei Okounkov, Terry Tao (Board members and program organizers) and a rotating Scientific Advisory Committee (SAC) help us reach into all parts of fundamental mathematics 5
  6. 6. What Distinguishes MSRI? MSRI is a pioneer in international engagement • Increases connections between US researchers and the international community • In 2020, MSRI partnered with universities in Australia, Canada, China, England, Greece, and Switzerland on Summer Graduate Schools in emerging areas, using non-NSF funds and international support. • Co-founders of the Banff International Research Station (BIRS) and Casa Matemática Oaxaca (CMO), where MSRI remains a full partner in governance and in scientific interactions 6
  7. 7. What Distinguishes MSRI? Public Understanding of Mathematics • Congressional Briefings 2x/year • Numberphile—most popular informal math channel on YouTube: over 3M subscribers, 450M ”views” (Numberphile.com) • Films, such as Navajo Math Circles, and Secrets of the Surface, the Mathematical Vision of Maryam Mirzakhani • National Math Festival • Mathical Books—a prize for children’s literature related to mathematics 7
  8. 8. • To formalize and facilitate the flow of information between the corporate world and MSRI we have developed a corporate partnership program. • Corporate members may choose from three tiers depending on the level of interaction and sponsorship desired. • Custom sponsorship and individualized packages are also available. 8 Corporate Partners Program
