Hello,
My name is Rafael Ferreira, and I am a Ph.D. student at Nova School of Science and Technology in Portugal.
I finished my M.SC. in Computer Science in 2021, also at Nova School of Science and Technology with my thesis, where I approached the problem of conversational search using state-of-the-art models in query-rewriting, response re-ranking, and context tracking.
Currently, I am working on the subject of dialogue policy for conversational task-oriented dialogue agents to guide the conversation to a successful state using the underlying context to choose the next system action.
My research aims to improve the behavior and naturalness of conversational agents with the aim of developing next-generation systems that exhibit more human-like understanding and characteristics.
My interests include Conversational Agents, Natural Language Processing, Machine Learning, and Multimodal AI.
