M3BAT: Unsupervised Domain Adaptation for Multimodal Mobile Sensing with Multi-Branch Adversarial Training

no code implementations26 Apr 2024 Lakmal Meegahapola, Hamza Hassoune, Daniel Gatica-Perez

Moreover, we proposed a novel improvement over DANN, called M3BAT, unsupervised domain adaptation for multimodal mobile sensing with multi-branch adversarial training, to account for the multimodality of sensor data during domain adaptation with multiple branches.

Locally Private Graph Neural Networks

1 code implementation9 Jun 2020 Sina Sajadmanesh, Daniel Gatica-Perez

In this paper, we study the problem of node data privacy, where graph nodes have potentially sensitive data that is kept private, but they could be beneficial for a central server for training a GNN over the graph.
