Instruction Pre-Training: Language Models are Supervised Multitask Learners (2024.emnlp-main)
Copied to clipboard
| Challenge: | Unsupervised multitask pre-training has been the key to the success of language models (LMs) however, scaling it in the post-training stage trends towards better generalization. |
| Approach: | They propose a framework that augments massive raw corpora with instruction-response pairs to pre-train LMs. |
| Outcome: | The proposed framework augments massive raw corpora with instruction-response pairs to pre-train LMs. |

| Challenge: | Existing methods for evaluating expressive speech focus on word accuracy, naturalness, signal quality, or emotional intensity at the utterance level. |
| Approach: | They propose a framework for Evaluating Expressive Appropriateness in speech that assesses whether a speech sample aligns with the underlying communicative intent implied by its discourse-level narrative context. |
| Outcome: | The proposed framework outperforms existing speech evaluation and analysis systems on a human-annotated test set. |
ToneCraft: Cantonese Lyrics Generation with Harmony of Tones and Pitches (2025.emnlp-main)
Copied to clipboard
| Challenge: | Current research has not addressed the challenge of generating harmonious Cantonese lyrics. |
| Approach: | They propose a framework for generating Cantonese lyrics that ensures tonal and melodic harmony. |
| Outcome: | The proposed framework ensures tonal and melodic harmony while preserving character count and quality. |

| Challenge: | Large Language Models (LLMs) have impressive capabilities but need for task-specific prompt engineering can hinder their generalization. |
| Approach: | They propose a lightweight and versatile retriever that automatically retrieves prompts for a given zero-shot task input. |
| Outcome: | The proposed model is universally applicable across tasks and models . it mitigates hallucination problem in chatGPT, and it improves even the strongest LLMs. |
