Learning with fuzzy hypergraphs: a topical approach to query-oriented text summarization
Hadrien Van Lierde, Tommy W. S. Chow
Existing graph-based methods for extractive document summarization represent sentences of a corpus as the nodes of a graph or a hypergraph in which edges depict relationships of le…
Query-oriented text summarization based on hypergraph transversals
Hadrien Van Lierde, Tommy W. S. Chow
Existing graph- and hypergraph-based algorithms for document summarization represent the sentences of a corpus as the nodes of a graph or a hypergraph in which the edges represent…
Spectral clustering algorithms for the detection of clusters in block-cyclic and block-acyclic graphs
H. Van Lierde, T. W. S. Chow, J. -C. Delvenne
We propose two spectral algorithms for partitioning nodes in directed graphs respectively with a cyclic and an acyclic pattern of connection between groups of nodes. Our methods ar…
Exactly Robust Kernel Principal Component Analysis
Jicong Fan, Tommy W. S. Chow
Robust principal component analysis (RPCA) can recover low-rank matrices when they are corrupted by sparse noises. In practice, many matrices are, however, of high-rank and hence c…
