Sparse Coding with Invariance Constraints
We suggest a new approach to optimize the learning of sparse features under the constraints of explicit transformation symmetries imposed on the set of feature vectors. Given a set...

An Image Coding and Reconstruction Scheme for Mobile Computing
An asynchronous transfer mode (ATM) wireless network has bursty and high error rates. To combat the contiguous bit loss due to damaged or dropped packets, this paper presents a cod...

Aggregate Message Authentication Codes
We propose and investigate the notion of aggregate message authentication codes (MACs) which have the property that multiple MAC tags, computed by (possibly) different senders on ...

Flexcode - flexible audio coding
Modern networks are highly variable and, as a result, source coders are commonly used under conditions that they were not designed for. We address this problem with a source-codin...

Rate and power allocation under the pairwise distributed source coding constraint
We explore the problem of rate and power allocation for a sensor network where pairwise distributed source coding is employed (introduced by Roumy and Gesbert `07). For noiseless n...
