Direct Evaluation of Chain-of-Thought in Multi-hop Reasoning with Knowledge Graphs (2024.findings-acl)
Copied to clipboard
| Challenge: | Prior research on evaluating large language models focused on answer accuracy, neglecting the correctness of the generated CoT. |
| Approach: | They propose a discriminative and generative CoT evaluation paradigm to assess LLMs’ knowledge of reasoning and the accuracy of the generated CoT. |
| Outcome: | The proposed evaluation paradigm assesses LLMs’ knowledge of reasoning and the accuracy of the generated CoT. |
Vietnamese Automatic Speech Recognition: A Revisit (2026.findings-eacl)
Copied to clipboard
| Challenge: | Existing datasets with low quality and inconsistent annotations are insufficient for high-quality models. |
| Approach: | They propose a pipeline for aggregating and preprocessing high-quality ASR datasets from diverse, potentially noisy, open-source sources. |
| Outcome: | The proposed pipeline provides a foundation for training and evaluating state-of-the-art Vietnamese ASR systems. |
Zero-Shot Text-to-Speech for Vietnamese (2025.acl-short)
Copied to clipboard
| Challenge: | Text-to-speech (TTS) synthesis has seen significant advancements in recent years. |
| Approach: | They propose to use PhoAudiobook to curated 941 hours of high-quality audio for Vietnamese text-to-speech models. |
| Outcome: | The proposed model improves on VALL-E, VoiceCraft, and XTTS-V2 models, highlighting their robustness in handling diverse linguistic contexts. |
