Desirable Companion for Vertical Federated Learning: New Zeroth-Order Gradient Based Algorithm

no code implementations19 Mar 2022 Qingsong Zhang, Bin Gu, Zhiyuan Dang, Cheng Deng, Heng Huang

Based on that, we propose a novel and practical VFL framework with black-box models, which is inseparably interconnected to the promising properties of ZOO.

SelfSAGCN: Self-Supervised Semantic Alignment for Graph Convolution Network

1 code implementation CVPR 2021 Xu Yang, Cheng Deng, Zhiyuan Dang, Kun Wei, Junchi Yan

Specifically, the Identity Aggregation is applied to extract semantic features from labeled nodes, the Semantic Alignment is utilized to align node features obtained from different aspects using the class central similarity.

Nearest Neighbor Matching for Deep Clustering

1 code implementation CVPR 2021 Zhiyuan Dang, Cheng Deng, Xu Yang, Kun Wei, Heng Huang

Specifically, for the local level, we match the nearest neighbors based on batch embedded features, as for the global one, we match neighbors from overall embedded features.

Doubly Contrastive Deep Clustering

1 code implementation9 Mar 2021 Zhiyuan Dang, Cheng Deng, Xu Yang, Heng Huang

In this paper, we present a novel Doubly Contrastive Deep Clustering (DCDC) framework, which constructs contrastive loss over both sample and class views to obtain more discriminative features and competitive results.

Federated Doubly Stochastic Kernel Learning for Vertically Partitioned Data

no code implementations14 Aug 2020 Bin Gu, Zhiyuan Dang, Xiang Li, Heng Huang

In this paper, we focus on nonlinear learning with kernels, and propose a federated doubly stochastic kernel learning (FDSKL) algorithm for vertically partitioned data.

Multi-Scale Fusion Subspace Clustering Using Similarity Constraint

no code implementations CVPR 2020 Zhiyuan Dang, Cheng Deng, Xu Yang, Heng Huang

To tackle this issue, deep subspace clustering (DSC) networks based on deep autoencoder (DAE) have been proposed, which non-linearly map the raw form data into a latent space well-adapted to subspace clustering.
