Bipartite Graph based Construction of Compressed Sensing Matrices
Weizhi Lu, Kidiyo Kpalma, Joseph Ronsin
This paper proposes an efficient method to construct the bipartite graph with as many edges as possible while without introducing the shortest cycles of length equal to 4. The bina…
Sparse Matrix-based Random Projection for Classification
Weizhi Lu, Weiyu Li, Kidiyo Kpalma +1
As a typical dimensionality reduction technique, random projection can be simply implemented with linear projection, while maintaining the pairwise distances of high-dimensional da…
Compressed Sensing Matrices: Binary vs. Ternary
Weizhi Lu, Kidiyo Kpalma, Joseph Ronsin
Binary matrix and ternary matrix are two types of popular sensing matrices in compressed sensing for their competitive performance and low computation. However, to the best of our…
Near-optimal Binary Compressed Sensing Matrix
Weizhi Lu, Weiyu Li, Kidiyo Kpalma +1
Compressed sensing is a promising technique that attempts to faithfully recover sparse signal with as few linear and nonadaptive measurements as possible. Its performance is largel…
