Attention to Neural Plagiarism: Diffusion Models Can Plagiarize Your Copyrighted Images!

ICCV 2025poster

In this paper, we highlight a critical threat posed by emerging neural models--data plagiarism. We demonstrate how modern neural models (e.g., diffusion models) can effortlessly replicate copyrighted images, even when protected by advanced watermarking techniques. To expose the vulnerability in copy…

Unifying Within and Across: Intra-Modality Multi-View Fusion and Inter-Modality Alignment for Knowledge Graph Completion

ICASSP 2025accepted

Multi-modal knowledge graph completion (MMKGC) enhances the structural and semantic richness of knowledge graphs by integrating diverse information across modalities. However, existing methods often either overlook the diversity within a single modality or fail to ensure effective cross-modality ali…

Towards Improved Proxy-Based Deep Metric Learning via Data-Augmented Domain Adaptation

AAAI 2024technical

Deep Metric Learning (DML) plays an important role in modern computer vision research, where we learn a distance metric for a set of image representations. Recent DML techniques utilize the proxy to interact with the corresponding image samples in the embedding space. However, existing proxy-based D…

FF-LINS: A Consistent Frame-to-Frame Solid-State-LiDAR-Inertial State Estimator

RA-L 2023

Most of the existing LiDAR-inertial navigation systems are based on frame-to-map registrations, leading to inconsistency in state estimation. The newest solid-state LiDAR with a non-repetitive scanning pattern makes it possible to achieve a consistent LiDAR-inertial estimator by employing a frame-to

On Calibrating Semantic Segmentation Models: Analyses and an Algorithm

CVPR 2023poster

We study the problem of semantic segmentation calibration. Lots of solutions have been proposed to approach model miscalibration of confidence in image classification. However, to date, confidence calibration research on semantic segmentation is still limited. We provide a systematic study on the ca…

Anti-Neuron Watermarking: Protecting Personal Data against Unauthorized Neural Networks

ECCV 2022poster

"We study protecting a user’s data (e.g., images in this work) against a learner’s unauthorized use in training neural networks. It is especially challenging when the user’s data is only a tiny percentage of the learner’s complete training set. We revisit the traditional watermarking under modern de…

BachGAN: High-Resolution Image Synthesis From Salient Object Layout

CVPR 2020poster

We propose a new task towards more practical applications for image generation - high-quality image synthesis from salient object layout. This new setting requires users to provide only the layout of salient objects (i.e., foreground bounding boxes and categories) and lets the model complete the dra…

Improving Object Detection with Selective Self-Supervised Self-Training

ECCV 2020poster

We study how to leverage Web images to augment human-curated object detection datasets. Our approach is two-pronged. On the one hand, we retrieve Web images by image-to-image search, which incurs less domain shift from the curated data than other search methods. The Web images are diverse, supplying…

Neural Networks Are More Productive Teachers Than Human Raters: Active Mixup for Data-Efficient Knowledge Distillation From a Blackbox Model

CVPR 2020oral

We study how to train a student deep neural network for visual recognition by distilling knowledge from a blackbox teacher model in a data-efficient manner. Progress on this problem can significantly reduce the dependence on large-scale datasets for learning high-performing visual recognition models…

Rethinking Class-Balanced Methods for Long-Tailed Visual Recognition From a Domain Adaptation Perspective

CVPR 2020oral

Object frequency in the real world often follows a power law, leading to a mismatch between datasets with long-tailed class distributions seen by a machine learning model and our expectation of the model to perform well on all classes. We analyze this mismatch from a domain adaptation point of view.…

AET vs. AED: Unsupervised Representation Learning by Auto-Encoding Transformations Rather Than Data

CVPR 2019oral

The success of deep neural networks often relies on a large amount of labeled examples, which can be difficult to obtain in many real scenarios. To address this challenge, unsupervised methods are strongly preferred for training neural networks without using any labeled data. In this paper, we prese…
