Catastrophic Overfitting: A Potential Blessing in Disguise

no code implementations28 Feb 2024 Mengnan Zhao, Lihe Zhang, Yuqiu Kong, BaoCai Yin

To tackle this issue, we initially employ the feature activation differences between clean and adversarial examples to analyze the underlying causes of CO. Intriguingly, our findings reveal that CO can be attributed to the feature coverage induced by a few specific pathways.

Separable Multi-Concept Erasure from Diffusion Models

1 code implementation3 Feb 2024 Mengnan Zhao, Lihe Zhang, Tianhang Zheng, Yuqiu Kong, BaoCai Yin

Large-scale diffusion models, known for their impressive image generation capabilities, have raised concerns among researchers regarding social impacts, such as the imitation of copyrighted artistic styles.

EipFormer: Emphasizing Instance Positions in 3D Instance Segmentation

no code implementations9 Dec 2023 Mengnan Zhao, Lihe Zhang, Yuqiu Kong, BaoCai Yin

It enhances the initial instance positions through weighted farthest point sampling and further refines the instance positions and proposals using aggregation averaging and center matching.

Referring Image Segmentation Using Text Supervision

1 code implementation ICCV 2023 Fang Liu, Yuhao Liu, Yuqiu Kong, Ke Xu, Lihe Zhang, BaoCai Yin, Gerhard Hancke, Rynson Lau

Hence, we propose a novel weakly-supervised RIS framework to formulate the target localization problem as a classification process to differentiate between positive and negative text expressions.

Fast Adversarial Training with Smooth Convergence

1 code implementation ICCV 2023 Mengnan Zhao, Lihe Zhang, Yuqiu Kong, BaoCai Yin

To address this, we analyze the training process of prior FAT work and observe that catastrophic overfitting is accompanied by the appearance of loss convergence outliers.

Temporal Knowledge Graph Reasoning Triggered by Memories

1 code implementation17 Oct 2021 Mengnan Zhao, Lihe Zhang, Yuqiu Kong, BaoCai Yin

Specifically, the transient learning network considers transient memories as a static knowledge graph, and the time-aware recurrent evolution network learns representations through a sequence of recurrent evolution units from long-short-term memories.
