UQ-ViT: Harmonizing Extreme Activations with Hardware-Friendly Uniform Quantization in Vision Transformers

AAAI 2026technical

Post-Training Quantization enables efficient Vision Transformer (ViTs) deployment with a small calibration data, and its prevalent use of uniform quantization harnesses AI accelerator matrix cores for high-speed inference. However, the application of uniform quantization is fundamentally challenged

Not All Tokens Matter All The Time: Dynamic Token Aggregation Towards Efficient Detection Transformers

ICML 2025poster

The substantial computational demands of detection transformers (DETRs) hinder their deployment in resource-constrained scenarios, with the encoder consistently emerging as a critical bottleneck. A promising solution lies in reducing token redundancy within the encoder. However, existing methods per…

Bidirectional Reciprocative Information Communication for Few-Shot Semantic Segmentation

ICML 2024poster

Existing few-shot semantic segmentation methods typically rely on a one-way flow of category information from support to query, ignoring the impact of intra-class diversity. To address this, drawing inspiration from cybernetics, we introduce a Query Feedback Branch (QFB) to propagate query informati…

Multi-grained Temporal Prototype Learning for Few-shot Video Object Segmentation

ICCV 2023poster

Few-Shot Video Object Segmentation (FSVOS) aims to segment objects in a query video with the same category defined by a few annotated support images. However, this task was seldom explored. In this work, based on IPMT, a state-of-the-art few-shot image segmentation method that combines external supp…

Intermediate Prototype Mining Transformer for Few-Shot Semantic Segmentation

NeurIPS 2022accept

Few-shot semantic segmentation aims to segment the target objects in query under the condition of a few annotated support images. Most previous works strive to mine more effective category information from the support to match with the corresponding objects in query. However, they all ignored the ca…

Learning Non-Target Knowledge for Few-Shot Semantic Segmentation

CVPR 2022poster

Existing studies in few-shot semantic segmentation only focus on mining the target object information, however, often are hard to tell ambiguous regions, especially in non-target regions, which include background (BG) and Distracting Objects (DOs). To alleviate this problem, we propose a novel frame…

SCAN: Cross Domain Object Detection with Semantic Conditioned Adaptation

AAAI 2022technical

The domain gap severely limits the transferability and scalability of object detectors trained in a specific domain when applied to a novel one. Most existing works bridge the domain gap by minimizing the domain discrepancy in the category space and aligning category-agnostic global features. Though…

Weakly Supervised Rotation-Invariant Aerial Object Detection Network

CVPR 2022poster

Object rotation is among long-standing, yet still unexplored, hard issues encountered in the task of weakly supervised object detection (WSOD) from aerial images. Existing predominant WSOD approaches built on regular CNNs which are not inherently designed to tackle object rotations without correspon…
