It has recently been shown that only a small number of samples from a low-rank matrix are necessary to reconstruct the entire matrix. We bring this to bear on computer vision problems that utilize low-dimensional subspaces, demonstrating that subsampling can improve computation speed while still allowing for accurate subspace learning. We present GRASTA, Grassmannian Robust Adaptive Subspace Tracking...
A new on-die temperature sensor that operates at low supply voltages and exhibits low process sensitivity and good linearity over a wide temperature range is introduced. When compared to conventional structures which have limited supply voltage headroom at the slow-n process corner, the new structures have sufficient headroom to practically operate well over all process corners. When implemented in...
Based on the endogenous growth model with expanding-variety of intermediates, this article studies the effects of intellectual property rights protection, technology gap and absorptive capability on the technology progress in developing countries. It is shown that the relationship between intellectual property rights protection and technology progress in developing countries is non-monotonically....
Similarity calculation has many applications, such as information retrieval, and collaborative filtering, among many others. It has been shown that link-based similarity measure, such as SimRank, is very effective in characterizing the object similarities in networks, such as the Web, by exploiting the object-to-object relationship. Unfortunately, it is prohibitively expensive to compute the link-based...
In this paper, a stream color image cryptography has been proposed based on spatiotemporal chaos system. One-way coupled map lattices (OCML) are used to generate pseudorandom sequences and then encrypt image pixels one by one. By iterating randomly chosen chaotic maps from a set of chaotic maps for certain times, the generated pseudorandom sequences obtain high initial-value sensitivity and good randomness...
Influence between objects needs to be assessed in many applications. Lots of measures have been proposed, but a domain-independent method is still expected. In this paper, we give a probabilistic definition of influence based on the random walker model on graphs. Two approaches, linear systems method and Basic InfRank algorithm, are shown and return equal results, but Basic InfRank is more efficient...
Until recently a closed-form expression for the output voltage of the most basic bandgap references was not available making it difficult to analytically and systematically determine the effects of the temperature dependence of non-ideal components on the magnitude of the output voltage, on the inflection point location, and on the curvature of these bandgap circuits. In this paper several non-ideal...
