Copied to clipboard
| Challenge: | Existing approaches to solve catastrophic forgetting problem are varied . current approaches to learn continuous learning are based on replay-based methods . |
| Approach: | They propose to calibrate parameters and logits so that preserving old parameters and generalized learning on new concepts can be solved simultaneously. |
| Outcome: | The proposed model achieves state-of-the-art performance in all scenarios. |
Contextual Rephrase Detection for Reducing Friction in Dialogue Systems (2021.emnlp-main)
Copied to clipboard
| Challenge: | Large-scale conversational AI based dialogue systems like Alexa, Siri, and Google Assistant, are getting more and more prevalent in real-world applications to help users across the globe. |
| Approach: | They propose a contextual rephrase detection model ContReph to automatically identify rephrasings from multi-turn dialogues using contextual information and user-agent interaction signals. |
| Outcome: | The proposed model outperforms the pairwise rephrase detection models by leveraging the context and user-agent interaction signals. |
Dual Contrastive Learning Framework for Incremental Text Classification (2023.findings-emnlp)
Copied to clipboard
| Challenge: | In incremental learning, large models learn and refresh knowledge continuously . many approaches have been proposed to preserve knowledge from previous tasks while learning new concepts in online NLP applications. |
| Approach: | They propose a dual contrastive learning framework that fosters transferability across different tasks . they use global contrastive and task-specific learning to promote a generalized embedding space . |
| Outcome: | The proposed framework outperforms the current state-of-the-art methods on text datasets. |
