Efficient Scheduling of Pigeons for a Constrained Delay Tolerant Application
TLDR
Pigeon networks are a special type of delay tolerant networks (DTNs) that borrows the ancient idea of using pigeons as the telecommunication method. Expand

Image tag refinement by regularized latent Dirichlet allocation
TLDR
We propose to do tag refinement from the angle of topic modeling and present a novel graphical model, regularized latent Dirichlet allocation, which estimates the latent topics for each document, with making use of other documents. Expand
