Why Attend to Everything? Focus is the Key

Hengshuai Yao, Xing Chen, Ahmed Murtadha +8

Standard attention scales quadratically with sequence length. Efficient attention methods reduce this O(n^2) cost, but when retrofitted into pretrained models, they often degrade p…

GAIN: Multiplicative Modulation for Domain Adaptation

Hengshuai Yao, Xing Chen, Ahmed Murtadha +1

Adapting LLMs to new domains causes forgetting because standard methods (e.g., full fine-tuning, LoRA) inject new directions into the weight space. We show that forgetting is gover…

Thin Keys, Full Values: Reducing KV Cache via Low-Dimensional Attention Selection

Hengshuai Yao, Xing Chen, Ahmed Murtadha +1

Standard Transformer attention uses identical dimensionality for queries, keys, and values, yet these components serve different roles: queries and keys produce scalar attention we…

Learning Optimal Prompt Ensemble for Multi-source Visual Prompt Transfer

Enming Zhang, Liwen Cao, Yanru Wu +2

Prompt tuning has emerged as a lightweight strategy for adapting foundation models to downstream tasks, particularly for resource-constrained systems. As pre-trained prompts become…

TMT: Cross-domain Semantic Segmentation with Region-adaptive Transferability Estimation

Enming Zhang, Zhengyu Li, Yanru Wu +5

Recent advances in Vision Transformers (ViTs) have significantly advanced semantic segmentation performance. However, their adaptation to new target domains remains challenged by d…
