Zeroth Order Non-convex optimization with Dueling-Choice Bandits

Yichong Xu, Aparna Joshi, Aarti Singh +1

We consider a novel setting of zeroth order non-convex optimization, where in addition to querying the function value at a given point, we can also duel two points and get the poin…

Thresholding Bandit Problem with Both Duels and Pulls

Yichong Xu, Xi Chen, Aarti Singh +1

The Thresholding Bandit Problem (TBP) aims to find the set of arms with mean rewards greater than a given threshold. We consider a new setting of TBP, where in addition to pulling…

Multi-task Learning with Sample Re-weighting for Machine Reading Comprehension

Yichong Xu, Xiaodong Liu, Yelong Shen +2

We propose a multi-task learning framework to learn a joint Machine Reading Comprehension (MRC) model that can be applied to a wide range of MRC tasks in different domains. Inspire…
