DeFTA: A Plug-and-Play Decentralized Replacement for FedAvg

no code implementations6 Apr 2022 Yuhao Zhou, Minjia Shi, Yuxin Tian, Qing Ye, Jiancheng Lv

Federated learning (FL) is identified as a crucial enabler for large-scale distributed machine learning (ML) without the need for local raw dataset sharing, substantially reducing privacy concerns and alleviating the isolated data problem.

Continual Neural Mapping: Learning An Implicit Scene Representation from Sequential Observations

no code implementations ICCV 2021 Zike Yan, Yuxin Tian, Xuesong Shi, Ping Guo, Peng Wang, Hongbin Zha

We introduce an experience replay approach to tackle an exemplary task of continual neural mapping: approximating a continuous signed distance function (SDF) from sequential depth images as a scene geometry representation.

Generalizing Deep Models for Overhead Image Segmentation Through Getis-Ord Gi* Pooling

no code implementations23 Dec 2019 Xueqing Deng, Yi Zhu, Yuxin Tian, Shawn Newsam

Inspired by this, we investigate methods to inform or guide deep learning models for geospatial image analysis to increase their performance when a limited amount of training data is available or when they are applied to scenarios other than which they were trained on.
