Solving Factored MDPs with Exponential-Family Transition Models
Markov decision processes (MDPs) with discrete and continuous state and action components can be solved efficiently by hybrid approximate linear programming (HALP). The main idea ...

Convex Sparse Matrix Factorizations
We present a convex formulation of dictionary learning for sparse signal decomposition. Convexity is obtained by replacing the usual explicit upper bound on the dictionary size by...

A Factor-Two Approximation Algorithm for Two-Dimensional Phase Unwrapping
Two-dimensional phase unwrapping is the problem of deducing unambiguous "phase" from values known only modulo 2. Many authors agree that the objective of phase unwrappin...

Implicit brushing and target snapping: data exploration and sense-making on large displays
During grouping tasks for data exploration and sense-making, the criteria are normally not well-defined. When users are bringing together data objects thought to be similar in som...
