VDCBPI: an Approximate Scalable Algorithm for Large POMDPs
Existing algorithms for discrete partially observable Markov decision processes can at best solve problems of a few thousand states due to two important sources of intractability:...

Thin Junction Trees
We present an algorithm that induces a class of models with thin junction trees--models that are characterized by an upper bound on the size of the maximal cliques of their triang...

On High-Rate Cryptographic Compression Functions
Abstract. The security of iterated hash functions relies on the properties of underlying compression functions. We study highly efficient compression functions based on block ciphe...

Marker codes for channels with insertions and deletions
Coding for channels with synchronization errors is studied. Marker codes, each consisting of a low-density parity-check code with inserted markers, are developed. At low insertion...

Connectivity and fault-tolerance of hyperdigraphs
Directed hypergraphs are used to model networks whose nodes are connected by directed buses. We study in this paper two parameters related to the fault-tolerance of directed bus n...
