The Keccak hash function is one of the five finalists in NIST’s SHA-3 competition, and so far it showed remarkable resistance against practical collision finding attacks: Afte...
The key limiting factor in graphical model inference and learning is the complexity of the partition function. We thus ask the question: what are the most general conditions under...
The development of areas such as remote and airborne sensing, location based services, and geosensor networks enables the collection of large volumes of spatial data. These datase...
