Funded by the National Science Foundation (NSF), the Institute for Foundations of Data Science (IFDS) is a collaboration between the University of Washington, UC Santa Cruz, University of Wisconsin-Madison, and University of Chicago. Its mission is to develop a principled approach to the analysis of the ever-larger, more complex, and potentially biased data sets that play an increasingly important role in industry, government, and academia. The institute’s research will lead to methods that are more computationally efficient, robust to errors and incomplete or ambiguous data, and better able to respond and act in changing environments.
