DANCE: Diversity-attended Dynamic Caching with Asymmetric Quantization for Test-time Adaptation of Vision-Language Models (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing approaches to test-time adaptation of vision-language models measure prediction entropy but these samples tend to approach prototypes with limited coverage of data distributions. |
| Approach: | They propose a new approach for test-time adaptation of vision-language models . they construct a dynamic cache to store diversity-aware test samples . |
| Outcome: | The proposed approach is more efficient than current methods on augmented visual models. |
How Do Large Language Models Perform on PDE Discovery: A Coarse-to-fine Perspective (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods to identify partial differential equations using large language models suffer from performance degradation under extreme data scarcity. |
| Approach: | They propose a framework to use large language models to identify underlying partial differential equations out of very limited observations of a physical system. |
| Outcome: | The proposed framework is based on a coarse-to-fine paradigm to discover PDEs out of very limited observations of a physical system. |
