Deep Reinforcement Learning for natural language understanding and Dialogue Systems

Innovations in neural dialogue models promise to improve conversational AI. However, these models frequently lack foresight, handling answers one by one without considering long-term consequences. Traditional NLP techniques included reinforcement learning to address this. Deep reinforcement learning predicts future rewards in chatbot talks, according to this study. The model simulates agent interactions using policy gradient approaches, prioritizing sequences with essential conversational characteristics such as informativeness and coherence. Variety, answer length, and human assessment are emphasized in the evaluation of dialogue simulations, demonstrating the potential for interesting, protracted talks. This study is the first step toward developing a neural conversational model that prioritizes long-term discourse success.
