ReST-KV: Robust KV Cache Eviction with Layer-wise Output Reconstruction and Spatial-Temporal Smoothing

ICLR 2026poster

Large language models (LLMs) face growing challenges in efficient generative inference due to the increasing memory demands of Key-Value (KV) caches, especially for long sequences. Existing eviction methods typically retain KV pairs with high attention weights but overlook the impact of attention re…

GenPilot: A Multi-Agent System for Test-Time Prompt Optimization in Image Generation

EMNLP 2025

Text-to-image synthesis has made remarkable progress, yet accurately interpreting complex and lengthy prompts remains challenging, often resulting in semantic inconsistencies and missing details. Existing solutions, such as fine-tuning, are model-specific and require training, while prior automatic

PhysVLM-AVR: Active Visual Reasoning for Multimodal Large Language Models in Physical Environments

NeurIPS 2025poster

Visual reasoning in multimodal large language models (MLLMs) has primarily been studied in passive, static settings, limiting their effectiveness in real-world physical environments where an embodied agent must contend with incomplete information due to occlusion or a limited field of view. Humans,…

PhysVLM: Enabling Visual Language Models to Understand Robotic Physical Reachability

CVPR 2025poster

Understanding the environment and a robot's physical reachability is crucial for task execution. While state-of-the-art vision-language models (VLMs) excel in environmental perception, they often generate inaccurate or impractical responses in embodied visual reasoning tasks due to a lack of underst…

ZBS: Zero-Shot Background Subtraction via Instance-Level Background Modeling and Foreground Selection

CVPR 2023poster

Background subtraction (BGS) aims to extract all moving objects in the video frames to obtain binary foreground segmentation masks. Deep learning has been widely used in this field. Compared with supervised-based BGS methods, unsupervised methods have better generalization. However, previous unsuper…

C2AM Loss: Chasing a Better Decision Boundary for Long-Tail Object Detection

CVPR 2022poster

Long-tail object detection suffers from poor performance on tail categories. We reveal that the real culprit lies in the extremely imbalanced distribution of the classifier's weight norm. For conventional softmax cross-entropy loss, such imbalanced weight norm distribution yields ill conditioned dec…

Obj2Seq: Formatting Objects as Sequences with Class Prompt for Visual Tasks

NeurIPS 2022accept

Visual tasks vary a lot in their output formats and concerned contents, therefore it is hard to process them with an identical structure. One main obstacle lies in the high-dimensional outputs in object-level visual tasks. In this paper, we propose an object-centric vision framework, Obj2Seq. Obj2Se…

UniVIP: A Unified Framework for Self-Supervised Visual Pre-Training

CVPR 2022poster

Self-supervised learning (SSL) holds promise in leveraging large amounts of unlabeled data. However, the success of popular SSL methods has limited on single-centric-object images like those in ImageNet and ignores the correlation among the scene and instances, as well as the semantic difference of…

Adaptive Class Suppression Loss for Long-Tail Object Detection

CVPR 2021poster

To address the problem of long-tail distribution for the large vocabulary object detection task, existing methods usually divide the whole categories into several groups and treat each group with different strategies. These methods bring the following two problems. One is the training inconsistency…

MST: Masked Self-Supervised Transformer for Visual Representation

NeurIPS 2021poster

Transformer has been widely used for self-supervised pre-training in Natural Language Processing (NLP) and achieved great success. However, it has not been fully explored in visual self-supervised learning. Meanwhile, previous methods only consider the high-level feature and learning representation…

Large Batch Optimization for Object Detection: Training COCO in 12 Minutes

ECCV 2020poster

Most of existing object detectors usually adopt a small training batch size ( ~16), which severely hinders the whole community from exploring large-scale datasets due to the extremely long training procedure. In this paper, we propose a versatile large batch optimization framework for object detecti…

CoupleNet: Coupling Global Structure With Local Parts for Object Detection

ICCV 2017poster

The region-based Convolutional Neural Network (CNN) detectors such as Faster R-CNN or R-FCN have already shown promising results for object detection by combining the region proposal subnetwork and the classification subnetwork together. Although R-FCN has achieved higher detection speed while keepi…
