Maximum Consensus by Weighted Influences of Monotone Boolean Functions

CVPR 2022poster

Maximisation of Consensus (MaxCon) is one of the most widely used robust criteria in computer vision. Tennakoon et al. (CVPR2021), made a connection between MaxCon and estimation of influences of a Monotone Boolean function. In such, there are two distributions involved: the distribution defining th…

Sparse Hypergraph Community Detection Thresholds in Stochastic Block Model

NeurIPS 2022accept

Community detection in random graphs or hypergraphs is an interesting fundamental problem in statistics, machine learning and computer vision. When the hypergraphs are generated by a {\em stochastic block model}, the existence of a sharp threshold on the model parameters for community detection was…

Consensus Maximisation Using Influences of Monotone Boolean Functions

CVPR 2021poster

Consensus maximisation (MaxCon), widely used for robust fitting in computer vision, aims to find the largest subset of data that fits the model within some tolerance level. In this paper, we outline the connection between MaxCon problem and the abstract problem of finding the maximum upper zero of a…

Unsupervised Learning for Robust Fitting: A Reinforcement Learning Approach

CVPR 2021poster

Robust model fitting is a core algorithm in a large number of computer vision applications. Solving this problem efficiently for highly contaminated datasets is, however, still challenging due to its underlying computational complexity. Recent attention has been focused on learning-based algorithms.…
