Inhomogeneous Hypergraph Clustering with Applications
Pan Li, Olgica Milenkovic
Hypergraph partitioning is an important problem in machine learning, computer vision and network analytics. A widely used method for hypergraph partitioning relies on minimizing a…
Efficient Rank Aggregation via Lehmer Codes
Pan Li, Arya Mazumdar, Olgica Milenkovic
We propose a novel rank aggregation method based on converting permutations into their corresponding Lehmer codes or other subdiagonal images. Lehmer codes, also known as inversion…
Multiclass MinMax Rank Aggregation
Pan Li, Olgica Milenkovic
We introduce a new family of minmax rank aggregation problems under two distance measures, the Kendall τ and the Spearman footrule. As the problems are NP-hard, we proceed to descr…
Motif Clustering and Overlapping Clustering for Social Network Analysis
Pan Li, Hoang Dau, Gregory Puleo +1
Motivated by applications in social network community analysis, we introduce a new clustering paradigm termed motif clustering. Unlike classical clustering, motif clustering aims t…
