We consider a basic caching system, where a single server with a database of N files (e.g. movies) is connected to a set of K users through a shared bottleneck link. Each user has a local cache memory with a size of M files. The system operates in two phases: a placement phase, where each cache memory is populated up to its size from the database, and a following delivery phase, where each user requests...
We consider a cache network, where a single server is connected to multiple users via a shared bottleneck link. The server has a set of files, which can be cached by each user in a prefetching phase. In a following delivery phase, each user requests a file and the server delivers user demands as efficiently as possible by taking into account their cache contents. We focus on an important and commonly...
As a derivative of Restricted Boltzmann Machine (RBM), classification RBM (Class RBM) is proved to be an effective classifier with a probabilistic interpretation. Several elegant learning methods/models related to Class RBM have been proposed. This paper proposes and analyzes a Rényi divergence based generalization for discriminative learning objective of Class RBM. Specifically, we extend the Conditional...
