Expectation-maximization for sparse and non-negative PCA
We study the problem of finding the dominant eigenvector of the sample covariance matrix, under additional constraints on the vector: a cardinality constraint limits the number of...

Moving Block Sequence and Organizational Evolutionary Algorithm for General Floorplanning
⎯A new nonslicing floorplan representation, the moving block sequence (MBS), is proposed in this paper. Our idea of the MBS originates from the observation that placing blocks on...

SPIRAL out of convexity: sparsity-regularized algorithms for photon-limited imaging
The observations in many applications consist of counts of discrete events, such as photons hitting a detector, which cannot be effectively modeled using an additive bounded or Ga...

Stateless Routing in Network Simulations
The memory resources required by network simulations can grow quadratically with size of the simulated network. In simulations that use routing tables at each node to perform perh...
