A novel method for anomaly detection in hyperspectral images (HSIs) is proposed based on low-rank and sparse representation based on the separation of the background and the anomalies in the observed data.
Query dependent pseudo-relevance feedback based on wikipedia
This work proposes and proposes and studies the effectiveness of three methods for expansion term selection, each modeling the Wikipedia based pseudo-relevance information from a different perspective, and incorporates the expansion terms into the original query and uses language modeling IR to evaluate these methods.
WiFinger: talk to your smart devices with finger-grained gesture
WiFinger is deigned to recognize a set of finger-grained gestures, which are further used to realize continuous text input in off-the-shelf WiFi devices, and achieves up to 90.4% average classification accuracy for recognizing 9 digits finger- grained gestures from American Sign Language (ASL).

A crucial component of ROAD is a novel projection-based scheme for quadratic (both polynomial and posynomial) performance modeling, which allows the approach to scale well to large problem sizes.
Global Concave Minimization for Optimal Spectrum Balancing in Multi-User DSL Networks
A modified prismatic branch-and-bound algorithm, which only requires solving a sequence of linear programming subproblems, is applied to find the global optimum with substantial reduction in complexity especially for large modems.
