Semantic Hierarchical Prompt Tuning for Parameter-Efficient Fine-Tuning

ICASSP 2025accepted

As the scale of vision models continues to grow, Visual Prompt Timing (VPT) has emerged as a parameter-efficient transfer learning technique, noted for its superior performance compared to full fine-tuning. However, indiscriminately applying prompts to every layer without considering their inherent…

Evaluating the Validity of Word-level Adversarial Attacks with Large Language Models

ACL 2024findings

Deep neural networks exhibit vulnerability to word-level adversarial attacks in natural language processing. Most of these attack methods adopt synonymous substitutions to perturb original samples for crafting adversarial examples while attempting to maintain semantic consistency with the originals.…

W2P: Switching from Weak Supervision to Partial Supervision for Semantic Segmentation

AAAI 2024technical

Current weakly-supervised semantic segmentation (WSSS) techniques concentrate on enhancing class activation maps (CAMs) with image-level annotations. Yet, the emphasis on producing these pseudo-labels often overshadows the pivotal role of training the segmentation model itself. This paper underscore…

Low-Confidence Samples Mining for Semi-supervised Object Detection

IJCAI 2023poster

Reliable pseudo labels from unlabeled data play a key role in semi-supervised object detection (SSOD). However, the state-of-the-art SSOD methods all rely on pseudo labels with high confidence, which ignore valuable pseudo labels with lower confidence. Additionally, the insufficient excavation for u…

Semi-supervised Object Detection with Adaptive Class-Rebalancing Self-Training

AAAI 2022technical

While self-training achieves state-of-the-art results in semi-supervised object detection (SSOD), it severely suffers from foreground-background and foreground-foreground imbalances in SSOD. In this paper, we propose an Adaptive Class-Rebalancing Self-Training (ACRST) with a novel memory module call…
