Price Interpretability of Prediction Markets: A Convergence Analysis

no code implementations18 May 2022 Dian Yu, Jianjun Gao, WeiPing Wu, Zizhuo Wang

In broader markets with Constant Relative Risk Aversion (CRRA) utilities, we reveal that the limiting price can be characterized by systems of equations that encapsulate agent beliefs, risk parameters, and wealth.

Towards Fundamental Limits of Multi-armed Bandits with Random Walk Feedback

no code implementations3 Nov 2020 Tianyu Wang, Lin F. Yang, Zizhuo Wang

In this paper, we consider a new Multi-Armed Bandit (MAB) problem where arms are nodes in an unknown and possibly changing graph, and the agent (i) initiates random walks over the graph by pulling arms, (ii) observes the random walk trajectories, and (iii) receives rewards equal to the lengths of the walks.

A Near-Optimal Dynamic Learning Algorithm for Online Matching Problems with Concave Returns

no code implementations23 Jul 2013 Xiao Alison Chen, Zizhuo Wang

In this problem, a sequence of items arrive sequentially and each has to be allocated to one of the bidders, who bid a certain value for each item.

A Dynamic Near-Optimal Algorithm for Online Linear Programming

no code implementations16 Nov 2009 Shipra Agrawal, Zizhuo Wang, Yinyu Ye

A natural optimization model that formulates many online resource allocation and revenue management problems is the online linear program (LP) in which the constraint matrix is revealed column by column along with the corresponding objective coefficient.
