Vision
Non-standard methods—especially
ones involving moderately exponential algorithms—for evaluating large and structured sums of products have great prospects to significantly
advance the state of the art in algorithm theory and computational statistics.
Mission
The group's current mission is to implement the vision by studying
- algorithm theory of computing sums of products,
- sums of products in computational statistics,
- applications in science and technology.
- Fast sum-product algorithms for set functions
- Efficient algorithms for structure learning in graphical models
- Bounding by products: global bounds via local views
