Description:
This workshop focuses on how strategic agents, potentially including LLM based ones, interact in various machine learning environments and influence the system-wide outcome.
We are welcoming poster submissions around the following topics (but not restricted to):
Incentive Issues in LLMs
Mechanisms for Emerging Technologies such as Generative AIs
LLM-Based Agents & Coordination
Multi-agent Reasoning/Debating
Learning & Adaptation
Convergence in Strategic Online learning and Bandits
Preference Learning & Human Feedback
Information/Text Elicitation from GenAIs
Fairness / Ethics in LLMs
Game-Theoretic Foundations
Robustness & Adversarial Behavior in Strategic Settings
We are co-locating this workshop with EAI GameNets 2026 – 14th EAI International Conference on Game Theory for Networks GameNets is happening on Mar 26-27 in the same location

Unlocking the Value of Private Data: Differentially Private Synthetic Data GenerationAbstract
Despite massive data generation, access to sensitive datasets for research and development remains severely restricted, leading to "data poverty" and hindering innovation. Differentially private synthetic data generation offers a robust framework to create realistic, privacy-preserving datasets, unlocking their value without compromising individual confidentiality. In this talk, I will highlight our group's recent advancements in this domain, including novel algorithms and comprehensive benchmarking efforts to evaluate the utility and privacy trade-offs of synthetic data and talk about ongoing and future research directions addressing technical challenges and examining approaches across various data modalities.Biography
Tianhao Wang is an Assistant Professor at the Department of Computer Science at University of Virginia (UVA) since Jan 2022. He held a postdoc position at Carnegie Mellon University, earned his Ph.D. in Computer Science from Purdue University in 2021, and B.E. from Fudan University in 2015. His research focus is differential privacy and AI security and privacy. He has extensive publications in top security and database conferences. His work about differentially private synthetic data generation won multiple awards in NIST’s competition.TIME Thursday, April 2, 2026 at 12:00 PM - 1:00 PM

Reinforcement Learning and Control with Generative World ModelsAbstract
"Recent years have witnessed remarkable advances in generative modeling — from diffusion models and flow matching to autoregressive transformers and action-conditioned video models — that are rapidly closing the gap between learned simulators and the complexity of real-world dynamics. These developments open a principled path toward a new generation of reinforcement learning (RL) algorithms that harness the representational power of generative world models, naturally bridging model-based planning and model-free policy optimization within a unified framework.
In this talk, we introduce an inference-time policy optimization framework inspired by model predictive control (MPC), built around a pretrained policy and a learned world model (WM) of state transitions and rewards. While existing approaches use learned dynamics to generate imagined trajectories — either during training or at inference — they stop short of using those trajectory rollouts to optimize policy parameters on the fly. Our approach addresses this gap through a Differentiable World Model (DWM) pipeline that enables end-to-end gradient computation through WM trajectory rollouts, yielding inference-time policy optimization (ITPO) grounded in MPC. Across continuous-control benchmarks, ITPO with DWM consistently outperforms strong offline RL baselines. Beyond the core RL framework, we also discuss principled approaches to fine-tuning generative models under distribution shift, which enable the online deployment of such world-model-based policies."

On the Hardness of Learning Regular ExpressionsAbstract
"Despite the theoretical significance and wide practical use of regular expressions, the computational complexity of learning them has been largely unexplored. We study the computational hardness of improperly learning regular expressions in the PAC model and with membership queries. We show that PAC learning is hard even under the uniform distribution on the hypercube, and also prove hardness of distribution-free learning with membership queries. Furthermore, if regular expressions are extended with complement or intersection, we establish hardness of learning with membership queries even under the uniform distribution. We emphasize that these results do not follow from existing hardness results for learning DFAs or NFAs, since the descriptive complexity of regular languages can differ exponentially between DFAs, NFAs, and regular expressions.
This work is joint with Idan Attias, Nati Srebro, and Gal Vardi"
