Re-framing Incremental Deep Language Models for Dialogue Processing with Multi-task Learning (2020.coling-main)
Copied to clipboard
| Challenge: | Using a multi-task learning framework, we train a universal incremental dialogue processing model with four tasks of disfluency detection, language modelling, part-of-speech tagging and utterance segmentation in a simple deep recurrent setting. |
| Approach: | They propose a multi-task learning framework to train a universal incremental dialogue processing model with four tasks of disfluency detection, language modelling, part-of-speech tagging and utterance segmentation in a simple deep recurrent setting. |
| Outcome: | The proposed model outperforms individual tasks and delivers competitive performance. |
Disfluent Cues for Enhanced Speech Understanding in Large Language Models (2023.findings-emnlp)
Copied to clipboard
| Challenge: | a large number of language models struggle to handle disfluencies, authors say . when a speaker hesitates, interrupts themselves, repeats or corrects words, or abandons phrases, it can make their speech fragmented. |
| Approach: | They propose to use disfluent queries to “clean” spontaneous speech . they propose to apply disfluencies to models that use different types of speech repairs . |
| Outcome: | The proposed model improves on a reading comprehension task using disfluent queries . the results suggest that disfluencies can improve model performance, rather than their removal . |
Best of Both Worlds: Making High Accuracy Non-incremental Transformer-based Disfluency Detection Incremental (2021.acl-long)
Copied to clipboard
| Challenge: | Currently, Transformer-based text classifiers are not suitable for live incremental processing, operating only on the level of complete sentence inputs. |
| Approach: | They propose to introduce a method for word-by-word left-to-right incremental processing to Transformers such as BERT, models without an intrinsic sense of linear order. |
| Outcome: | The proposed method maintains high non-incremental performance while operating strictly incrementally. |
