Towards Clustering-friendly Representations: Subspace Clustering via Graph Filtering

1 code implementation18 Jun 2021 Zhengrui Ma, Zhao Kang, Guangchun Luo, Ling Tian

The success of subspace clustering depends on the assumption that the data can be separated into different subspaces.

Adversarial Privacy Preserving Graph Embedding against Inference Attack

1 code implementation30 Aug 2020 Kaiyang Li, Guangchun Luo, Yang Ye, Wei Li, Shihao Ji, Zhipeng Cai

In this paper, we propose Adversarial Privacy Graph Embedding (APGE), a graph adversarial training framework that integrates the disentangling and purging mechanisms to remove users' private information from learned node representations.

Fine-Grained Image Captioning with Global-Local Discriminative Objective

1 code implementation21 Jul 2020 Jie Wu, Tianshui Chen, Hefeng Wu, Zhi Yang, Guangchun Luo, Liang Lin

This is primarily due to (i) the conservative characteristic of traditional training objectives that drives the model to generate correct but hardly discriminative captions for similar images and (ii) the uneven word distribution of the ground-truth captions, which encourages generating highly frequent words/phrases while suppressing the less frequent but more concrete ones.
