FLOORA: A Human-Aligned Domain-Specific Language Model for Architectural Design

Sahand Rezaei-Shoshtari, Patryk Wozniczka, Shu Ishida +14

Foundation models are powerful generators, but many engineering domains require structured representations that general-purpose systems handle poorly. We introduce FLOORA (Floor La…

Graph of Agents: Principled Long Context Modeling by Emergent Multi-Agent Collaboration

Taejong Joo, Shu Ishida, Ivan Sosnovik +4

As a model-agnostic approach to long context modeling, multi-agent systems can process inputs longer than a large language model's context window without retraining or architectura…

Fairness in Reinforcement Learning with Bisimulation Metrics

Sahand Rezaei-Shoshtari, Hanna Yurchyk, Scott Fujimoto +2

Ensuring long-term fairness is crucial when developing automated decision making systems, specifically in dynamic and sequential environments. By maximizing their reward without co…

Policy Gradient Methods in the Presence of Symmetries and State Abstractions

Prakash Panangaden, Sahand Rezaei-Shoshtari, Rosie Zhao +2

Reinforcement learning (RL) on high-dimensional and complex problems relies on abstraction for improved efficiency and generalization. In this paper, we study abstraction in the co…

Hypernetworks for Zero-shot Transfer in Reinforcement Learning

Sahand Rezaei-Shoshtari, Charlotte Morissette, Francois Robert Hogan +2

In this paper, hypernetworks are trained to generate behaviors across a range of unseen task conditions, via a novel TD-based training objective and data from a set of near-optimal…

Continuous MDP Homomorphisms and Homomorphic Policy Gradient

Sahand Rezaei-Shoshtari, Rosie Zhao, Prakash Panangaden +2

Abstraction has been widely studied as a way to improve the efficiency and generalization of reinforcement learning algorithms. In this paper, we study abstraction in the continuou…

Learning Intuitive Physics with Multimodal Generative Models

Sahand Rezaei-Shoshtari, Francois Robert Hogan, Michael Jenkin +2

Predicting the future interaction of objects when they come into contact with their environment is key for autonomous agents to take intelligent and anticipatory actions. This pape…
