Follow Whom? Chinese Users Have Different Choice
Zhaoqun Chen, Pengfei Liu, Xiaohan Wang +1
Sina Weibo, which was launched in 2009, is the most popular Chinese micro-blogging service. It has been reported that Sina Weibo has more than 400 million registered users by the e…
The Convergence Guarantees of a Non-convex Approach for Sparse Recovery
Laming Chen, Yuantao Gu
In the area of sparse recovery, numerous researches hint that non-convex penalties might induce better sparsity than convex ones, but up until now those corresponding non-convex al…
Edge Balance Ratio: Power Law from Vertices to Edges in Directed Complex Network
Xiaohan Wang, Zhaoqun Chen, Pengfei Liu +1
Power law distribution is common in real-world networks including online social networks. Many studies on complex networks focus on the characteristics of vertices, which are alway…
On the Performance Bound of Sparse Estimation with Sensing Matrix Perturbation
Yujie Tang, Laming Chen, Yuantao Gu
This paper focusses on the sparse estimation in the situation where both the the sensing matrix and the measurement vector are corrupted by additive Gaussian noises. The performanc…
Efficient Recovery of Block Sparse Signals via Zero-point Attracting Projection
Jingbo Liu, Jian Jin, Yuantao Gu
In this paper, we consider compressed sensing (CS) of block-sparse signals, i.e., sparse signals that have nonzero coefficients occurring in clusters. An efficient algorithm, calle…
Quantization Reference Voltage of the Modulated Wideband Converter
Yaming Wang, Laming Chen, Yuantao Gu
The Modulated Wideband Converter (MWC) is a recently proposed analog-to-digital converter (ADC) based on Compressive Sensing (CS) theory. Unlike conventional ADCs, its quantization…
