VLUE: A New Benchmark and Multi-task Knowledge Transfer Learning for Vietnamese Natural Language Understanding (2024.findings-naacl)
Copied to clipboard
| Challenge: | a lack of standard evaluation metrics and benchmarks makes it difficult to identify strengths of Vietnamese NLP models. |
| Approach: | They propose to establish a standardized set of benchmarks for Vietnamese NLU . they propose to evaluate Vietnamese language understanding models using a pre-trained model . |
| Outcome: | The proposed model combines proficiency of a multilingual pre-trained model with Vietnamese linguistic knowledge. |
ViLL-E: Video LLM Embeddings for Retrieval (2026.acl-long)
Copied to clipboard
| Challenge: | Video Large Language Models excel at video understanding tasks where outputs are textual . however, they underperform specialized embedding-based models in Retrieval tasks . |
| Approach: | They propose a video-LLM-based model with an embedding generation mechanism that allows the model to "think longer" for complex videos and stop early for easy ones. |
| Outcome: | The proposed model outperforms specialized embedding-based models in video understanding tasks while remaining competitive on VideoQA tasks. |
Towards Robust Extractive Question Answering Models: Rethinking the Training Methodology (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Existing models lack robustness against distribution shifts and adversarial attacks when training on unanswerable questions in EQA datasets. |
| Approach: | They propose a novel loss function for the EQA problem to improve the robustness of extractive question answering models by adding adversarial questions to a crowdsourcing process. |
| Outcome: | The proposed method maintains in-domain performance while improving on out-of-domain datasets. |
