Papers with DQN
Learning to Search in Long Documents Using Document Structure (C18-1)
Copied to clipboard
| Challenge: | Reading comprehension models are dominated by recurrent neural networks (RNNs) as documents become longer and questions become complex, sequential reading becomes a significant bottleneck. |
| Approach: | They propose a reading comprehension framework that uses document trees to model an agent that interleaves quick navigation with more expensive answer extraction. |
| Outcome: | The proposed model improves question answering performance compared to existing models and has a strong information-retrieval baseline. |
A DQN-based Approach to Finding Precise Evidences for Fact Verification (2021.acl-long)
Copied to clipboard
| Challenge: | Existing methods for fact verification do not target the retrieval of precise evidences. |
| Approach: | They propose a DQN-based approach to retrieval of precise evidences . they propose best thresholds for determining the true labels of computed evidences. |
| Outcome: | The proposed method improves accuracy of fact verification by reducing label bias . it can retrieve evidence consisting of the first two sentences, but it can contain unnecessary sentences . |
Efficient Dialogue Complementary Policy Learning via Deep Q-network Policy and Episodic Memory Policy (2021.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for training dialogue policies rely on a single learning system, but it requires many rounds of interaction. |
| Approach: | They propose a complementary policy learning framework which exploits the complementary advantages of the episodic memory (EM) policy and the deep Q-network (DQN) policy. |
| Outcome: | The proposed framework outperforms existing methods relying on a single learning system on three dialogue datasets. |
