Crowdsourced Labeling for Worker-Task Specialization Model
Doyeon Kim, Hye Won Chung
We consider crowdsourced labeling under a -type worker-task specialization model, where each worker and task is associated with one particular type among a finite set of types a…
Robust Hypergraph Clustering via Convex Relaxation of Truncated MLE
Jeonghwan Lee, Daesung Kim, Hye Won Chung
We study hypergraph clustering in the weighted -uniform hypergraph stochastic block model (\textsf{-WHSBM}), where each edge consisting of nodes from the same community h…
Binary Classification with XOR Queries: Fundamental Limits and An Efficient Algorithm
Daesung Kim, Hye Won Chung
We consider a query-based data acquisition problem for binary classification of unknown labels, which has diverse applications in communications, crowdsourcing, recommender systems…
Weak Detection in the Spiked Wigner Model with General Rank
Ji Hyung Jung, Hye Won Chung, Ji Oon Lee
We study the statistical decision process of detecting the signal from a `signal+noise' type matrix model with an additive Wigner noise. We propose a hypothesis test based on the l…
