Secure Embedding Aggregation for Federated Representation Learning

no code implementations18 Jun 2022 Jiaxiang Tang, Jinbao Zhu, Songze Li, Lichao Sun

We consider a federated representation learning framework, where with the assistance of a central server, a group of $N$ distributed clients train collaboratively over their private data, for the representations (or embeddings) of a set of entities (e. g., users in a social network).

Not All Voxels Are Equal: Semantic Scene Completion from the Point-Voxel Perspective

no code implementations24 Dec 2021 Xiaokang Chen, Jiaxiang Tang, Jingbo Wang, Gang Zeng

Firstly, we transfer the voxelized scenes to point clouds by removing these visible empty voxels and adopt a deep point stream to capture semantic information from the scene efficiently.

Joint Implicit Image Function for Guided Depth Super-Resolution

1 code implementation19 Jul 2021 Jiaxiang Tang, Xiaokang Chen, Gang Zeng

Inspired by the recent progress in implicit neural representation, we propose to formulate the guided super-resolution as a neural implicit image interpolation problem, where we take the form of a general image interpolation but use a novel Joint Implicit Image Function (JIIF) representation to learn both the interpolation weights and values.
