Multi-VFL: A Vertical Federated Learning System for Multiple Data and Label Owners

no code implementations10 Jun 2021 Vaikkunth Mugunthan, Pawan Goyal, Lalana Kagal

Vertical Federated Learning (VFL) refers to the collaborative training of a model on a dataset where the features of the dataset are split among multiple data owners, while label information is owned by a single data owner.

Bias-Free FedGAN: A Federated Approach to Generate Bias-Free Datasets

no code implementations17 Mar 2021 Vaikkunth Mugunthan, Vignesh Gokul, Lalana Kagal, Shlomo Dubnov

Our approach generates metadata at the aggregator using the models received from clients and retrains the federated model to achieve bias-free results for image synthesis.

Investigating Bias in Image Classification using Model Explanations

no code implementations10 Dec 2020 Schrasing Tong, Lalana Kagal

We evaluated whether model explanations could efficiently detect bias in image classification by highlighting discriminating features, thereby removing the reliance on sensitive attributes for fairness calculations.

DPD-InfoGAN: Differentially Private Distributed InfoGAN

no code implementations22 Oct 2020 Vaikkunth Mugunthan, Vignesh Gokul, Lalana Kagal, Shlomo Dubnov

The Information Maximizing GAN (InfoGAN) is a variant of the default GAN that introduces feature-control variables that are automatically learned by the framework, hence providing greater control over the different kinds of images produced.
