Data-Driven Goal Recognition Design for General Behavioral Agents

no code implementations3 Apr 2024 Robert Kasumba, Guanghui Yu, Chien-Ju Ho, Sarah Keren, William Yeoh

Following existing literature, we use worst-case distinctiveness ($\textit{wcd}$) as a measure of the difficulty in inferring the goal of an agent in a decision-making environment.

Performative Prediction with Bandit Feedback: Learning through Reparameterization

no code implementations1 May 2023 Yatong Chen, Wei Tang, Chien-Ju Ho, Yang Liu

Specifically, we develop a {\em reparameterization} framework that reparametrizes the performative prediction objective as a function of the induced data distribution.

Optimal Query Complexity of Secure Stochastic Convex Optimization

no code implementations NeurIPS 2020 Wei Tang, Chien-Ju Ho, Yang Liu

The goal of the learner is to optimize the accuracy, i. e., obtaining an accurate estimate of the optimal point, while securing her privacy, i. e., making it difficult for the adversary to infer the optimal point.

Competitive Information Design for Pandora's Box

no code implementations5 Mar 2021 Bolin Ding, Yiding Feng, Chien-Ju Ho, Wei Tang

We study a natural competitive-information-design variant for the Pandora's Box problem (Weitzman 1979), where each box is associated with a strategic information sender who can design what information about the box's prize value to be revealed to the agent when the agent inspects the box.

Bandit Learning with Delayed Impact of Actions

no code implementations NeurIPS 2021 Wei Tang, Chien-Ju Ho, Yang Liu

In this paper, we formulate this delayed and long-term impact of actions within the context of multi-armed bandits.

Eliciting Categorical Data for Optimal Aggregation

no code implementations NeurIPS 2016 Chien-Ju Ho, Rafael Frongillo, Yi-Ling Chen

Our model generalizes both categories and enables the joint exploration of optimal elicitation and aggregation.

Low-Cost Learning via Active Data Procurement

no code implementations20 Feb 2015 Jacob Abernethy, Yi-Ling Chen, Chien-Ju Ho, Bo Waggoner

Our results in a sense parallel classic sample complexity guarantees, but with the key resource being money rather than quantity of data: With a budget constraint $B$, we give robust risk (predictive error) bounds on the order of $1/\sqrt{B}$.
