About me

I am currently pursuing my Ph.D. at Kashan University, under the guidance of Dr. Salimi. My primary research focus revolves around Task-based Dialogue Systems within the framework of Reinforcement Learning (RL). Specifically, my work is dedicated to advancing Attentional and Graph-based methodologies for learning structural state representations by incorporating both contextual and topological information in RL environments. Additionally, I explore Model-free RL algorithms, particularly variants of Deep Q-Networks (DQN), aiming to enhance policy learning within discrete state-action spaces, with a special emphasis on dialogue systems.
