Clustering with hypergraphs: the case for large hyperedges

P Purkait, TJ Chin, A Sadri… - IEEE transactions on …, 2016 - ieeexplore.ieee.org
The extension of conventional clustering to hypergraph clustering, which involves higher
order similarities instead of pairwise similarities, is increasingly gaining attention in …

Multiple model fitting as a set coverage problem

L Magri, A Fusiello - Proceedings of the IEEE conference on …, 2016 - openaccess.thecvf.com

Searching for representative modes on hypergraphs for robust geometric model fitting

H Wang, G **ao, Y Yan, D Suter - IEEE transactions on pattern …, 2018 - ieeexplore.ieee.org
In this paper, we propose a simple and effective geometric model fitting method to fit and
segment multi-structure data even in the presence of severe outliers. We cast the task of …

Uniform hypergraph partitioning: Provable tensor methods and sampling techniques

D Ghoshdastidar, A Dukkipati - Journal of Machine Learning Research, 2017 - jmlr.org
In a series of recent works, we have generalised the consistency results in the stochastic
block model literature to the case of uniform and non-uniform hypergraphs. The present …

A provable generalized tensor spectral method for uniform hypergraph partitioning

D Ghoshdastidar, A Dukkipati - International Conference on …, 2015 - proceedings.mlr.press
Matrix spectral methods play an important role in statistics and machine learning, and most
often the word 'matrix'is dropped as, by default, one assumes that similarities or affinities are …
