A Study on Dense and Sparse (Visual) Rewards in Robot Policy Learning

Abdalkarim Mohtasib, Gerhard Neumann, Heriberto Cuayahuitl

Deep Reinforcement Learning (DRL) is a promising approach for teaching robots new behaviour. However, one of its main limitations is the need for carefully hand-coded reward signal…

Deep Reinforcement Learning for Chatbots Using Clustered Actions and Human-Likeness Rewards

Heriberto Cuayáhuitl, Donghyeon Lee, Seonghan Ryu +3

Training chatbots using the reinforcement learning paradigm is challenging due to high-dimensional states, infinite action spaces and the difficulty in specifying the reward functi…

A Study on Dialogue Reward Prediction for Open-Ended Conversational Agents

Heriberto Cuayáhuitl, Seonghan Ryu, Donghyeon Lee +1

The amount of dialogue history to include in a conversational agent is often underestimated and/or set in an empirical and thus possibly naive way. This suggests that principled in…

Deep Reinforcement Learning for Multi-Domain Dialogue Systems

Heriberto Cuayáhuitl, Seunghak Yu, Ashley Williamson +1

Standard deep reinforcement learning methods such as Deep Q-Networks (DQN) for multiple tasks (domains) face scalability problems. We propose a method for multi-domain dialogue pol…

Strategic Dialogue Management via Deep Reinforcement Learning

Heriberto Cuayáhuitl, Simon Keizer, Oliver Lemon

Artificially intelligent agents equipped with strategic skills that can negotiate during their interactions with other natural or artificial agents are still underdeveloped. This p…
