Combining Cognitive Modeling and Reinforcement Learning for Clarification in Dialogue (2020.coling-main)
Copied to clipboard
| Challenge: | In many domains, dialogue systems need to work collaboratively with users to reconstruct meaning . this requires a system that can give targeted, effective feedback about the system’s understanding . |
| Approach: | They propose a system that collaborates on reference tasks that distinguish arbitrarily varying color patches from similar distractors and use crowd workers to test their approach. |
| Outcome: | The proposed system can distinguish varying color patches from distractors and elicit correct answers that the system understands. |
