BAFL: Federated Learning with Base Ablation for Cost Effective Communication

ICPR | IEEE Computer Society Digital Library
Two major challenges faced in this Federated Learning are data heterogeneity and high communication cost. We target the latter and propose a simple approach, BAFL to reduce communication costs. In contrast to the common practice of employing model compression techniques to reduce the total communication cost, we propose a fine-tuning approach to leverage the feature extraction ability of layers at different depths of deep neural networks.

An improved privacy preservation technique in health-cloud

ICT Express, Elsevier
I have proposed a hybrid technique which includes two different inference control techniques, query set size restriction and k-anonymity to ensure individuals’ privacy. A query set size restriction is used to prevent the sensitive data from inference attacks, whereas k-anonymity is implemented to protect the data from linking attacks.
