Transaction fee mechanism for Proof-of-Stake protocol
Wenpin Tang, David D. Yao
We study a mechanism design problem in the blockchain proof-of-stake (PoS) protocol. Our main objective is to extend the transaction fee mechanism (TFM) recently proposed in Chung…
Trading and wealth evolution in the Proof of Stake protocol
Wenpin Tang
With the increasing adoption of the Proof of Stake (PoS) blockchain, it is timely to study the economy created by such blockchain. In this chapter, we will survey recent progress o…
Finite and infinite weighted exchangeable sequences
Wenpin Tang
Motivated by recent interests in predictive inference under distribution shift, we study the problem of approximating finite weighted exchangeable sequences by a mixture of finite…
Policy Optimization for Continuous Reinforcement Learning
Hanyang Zhao, Wenpin Tang, David D. Yao
We study reinforcement learning (RL) in the setting of continuous time and space, for an infinite horizon with a discounted objective and the underlying dynamics driven by a stocha…
The convergence rate of vanishing viscosity approximations for mean field games
Wenpin Tang, Yuming Paul Zhang
Motivated by numerical challenges in first-order mean field games (MFGs) and the weak noise theory for the Kardar-Parisi-Zhang equation, we consider the problem of vanishing viscos…
Bayesian Geostatistics Using Predictive Stacking
Lu Zhang, Wenpin Tang, Sudipto Banerjee
We develop Bayesian predictive stacking for geostatistical models, where the primary inferential objective is to provide inference on the latent spatial random field and conduct sp…
Policy iteration for the deterministic control problems -- a viscosity approach
Wenpin Tang, Hung Vinh Tran, Yuming Paul Zhang
This paper is concerned with the convergence rate of policy iteration for (deterministic) optimal control problems in continuous time. To overcome the problem of ill-posedness due…
