Nonparametric Composite Hypothesis Testing in an Asymptotic Regime
Qunwei Li, Tiexing Wang, Donald J. Bucci +3
We investigate the nonparametric, composite hypothesis testing problem for arbitrary unknown distributions in the asymptotic regime where both the sample size and the number of hyp…
Optimal Crowdsourced Classification with a Reject Option in the Presence of Spammers
Qunwei Li, Pramod K. Varshney
We explore the design of an effective crowdsourcing system for an -ary classification task. Crowd workers complete simple binary microtasks whose results are aggregated to give…
Robust Decentralized Learning Using ADMM with Unreliable Agents
Qunwei Li, Bhavya Kailkhura, Ryan Goldhahn +2
Many machine learning problems can be formulated as consensus optimization problems which can be solved efficiently via a cooperative multi-agent system. However, the agents in the…
Convergence Analysis of Proximal Gradient with Momentum for Nonconvex Optimization
Qunwei Li, Yi Zhou, Yingbin Liang +1
In many modern machine learning applications, structures of underlying mathematical models often yield nonconvex optimization problems. Due to the intractability of nonconvexity, t…
Does Confidence Reporting from the Crowd Benefit Crowdsourcing Performance?
Qunwei Li, Pramod K. Varshney
We explore the design of an effective crowdsourcing system for an -ary classification task. Crowd workers complete simple binary microtasks whose results are aggregated to give…
