Focused Prefix Tuning for Controllable Text Generation (2023.acl-short)
Copied to clipboard
| Challenge: | Existing unannotated attributes could degrade models' performance . focus on the desired attribute can be achieved with focused prefix tuning . |
| Approach: | They propose focused prefix tuning to enable the control to focus on the desired attribute . they propose to reduce the number of unannotated attributes in a controllable text generation dataset . |
| Outcome: | The proposed approach achieves better control accuracy and text fluency than baseline models in single-attribute tasks. |
Integrating Pre-Trained Speech and Language Models for End-to-End Speech Recognition (2024.findings-acl)
Copied to clipboard
| Challenge: | Mainstream of automatic speech recognition (ASR) has shifted from pipeline methods to end-to-end (E2E) methods. |
| Approach: | They propose to integrate a pre-trained speech representation model and a large language model (LLM) for automatic speech recognition in an end-to-end manner. |
| Outcome: | The proposed model achieves comparable performance to modern E2E ASR models by utilizing powerful pre-training models with the proposed integrated approach. |

| Challenge: | democratization of AI aims to create a world where everyone can use AI . pre-trained models with high performance in Japanese are lagging in non-English-speaking communities . |
| Approach: | et al. released large-scale pre-trained models trained on large-data to improve access to AI . authors say the models are more accurate and more accurate than those trained in the English language . e-mail protected: email protected. |
| Outcome: | a new study shows that pre-trained models specialized for Japanese can achieve high performance in Japanese tasks. |
PSLM: Parallel Generation of Text and Speech with LLMs for Low-Latency Spoken Dialogue Systems (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Existing models that process both text and speech face problems in response generation latency. |
| Approach: | They propose to extend the input and output sequences of the language model to support the parallel generation of text and speech. |
| Outcome: | The proposed model improves latency while maintaining quality of response content while maintaining the quality of the response content. |
