A Worker-Task Specialization Model for Crowdsourcing: Efficient Inference and Fundamental Limits

1 code implementation19 Nov 2021 Doyeon Kim, Jeonghwan Lee, Hye Won Chung

Inferring correct labels from multiple noisy answers on data, however, has been a challenging problem, since the quality of the answers varies widely across tasks and workers.

Robust Hypergraph Clustering via Convex Relaxation of Truncated MLE

no code implementations23 Mar 2020 Jeonghwan Lee, Daesung Kim, Hye Won Chung

We study hypergraph clustering in the weighted $d$-uniform hypergraph stochastic block model ($d$\textsf{-WHSBM}), where each edge consisting of $d$ nodes from the same community has higher expected weight than the edges consisting of nodes from different communities.
