MetaCloak: Preventing Unauthorized Subject-driven Text-to-image Diffusion-based Synthesis via Meta-learning

1 code implementation22 Nov 2023 Yixin Liu, Chenrui Fan, Yutong Dai, Xun Chen, Pan Zhou, Lichao Sun

To solve these challenges, we propose MetaCloak, which solves the bi-level poisoning problem with a meta-learning framework with an additional transformation sampling process to craft transferable and robust perturbation.

Tackling Data Heterogeneity in Federated Learning with Class Prototypes

1 code implementation6 Dec 2022 Yutong Dai, Zeyuan Chen, Junnan Li, Shelby Heinecke, Lichao Sun, ran Xu

We propose FedNH, a novel method that improves the local models' performance for both personalization and generalization by combining the uniformity and semantics of class prototypes.

Learning Affinity-Aware Upsampling for Deep Image Matting

1 code implementation CVPR 2021 Yutong Dai, Hao Lu, Chunhua Shen

By looking at existing upsampling operators from a unified mathematical perspective, we generalize them into a second-order form and introduce Affinity-Aware Upsampling (A2U) where upsampling kernels are generated using a light-weight lowrank bilinear model and are conditioned on second-order features.

In defense of OSVOS

no code implementations19 Aug 2019 Yu Liu, Yutong Dai, Anh-Dzung Doan, Lingqiao Liu, Ian Reid

Through adding a common module, video loss, which we formulate with various forms of constraints (including weighted BCE loss, high-dimensional triplet loss, as well as a novel mixed instance-aware video loss), to train the parent network in the step (2), the network is then better prepared for the step (3), i. e. online fine-tuning on the target instance.

Index Network

6 code implementations11 Aug 2019 Hao Lu, Yutong Dai, Chunhua Shen, Songcen Xu

By viewing the indices as a function of the feature map, we introduce the concept of "learning to index", and present a novel index-guided encoder-decoder framework where indices are self-learned adaptively from data and are used to guide the downsampling and upsampling stages, without extra training supervision.
