Unsupervised feature learning has been shown to be effective at learning representations that perform well on image, video and audio classification. However, many existing feature learning algorithmsâ€¦ (More)

We consider the recovery of a low rank real-valued matrix M given a subset of noisy discrete (or quantized) measurements. Such problems arise in several applications such as collaborative filtering,â€¦ (More)

We consider the problem of noisy 1-bit matrix completion under an exact rank constraint on the true underlying matrix M*. Instead of observing a subset of the noisy continuous-valued entries of aâ€¦ (More)

We consider the problem of determining the location of sensor nodes in a wireless sensor ad hoc network when only connectivity information is available, i.e., one only knows if a pair of nodes isâ€¦ (More)

We consider the problem of testing whether a complex-valued vector random sequence is proper. Past work on this problem is limited to a sequence of independent Gaussian random vectors whereas weâ€¦ (More)

We consider the recovery of a low-rank matrix or image M given its noisy quantized (or discrete) measurements. We consider constrained maximum likelihood estimation of M, under a constraint on theâ€¦ (More)

This report presents an algorithm for accurate recognition of text on a business card, given an Android mobile phone camera image of the card in varying environmental conditions. First a MATLABâ€¦ (More)

In this paper, we consider the recovery of a low rank matrix M given a subset of noisy quantized (or ordinal) measurements. We consider a constrained maximum likelihood estimation of M, under aâ€¦ (More)

We consider the problem of testing whether a complex-valued vector random sequence is proper, i.e., if the sequence is uncorrelated with its complex conjugate. Previous nonparametric approaches toâ€¦ (More)
