Federated Learning Using Knowledge Distillation for CNN-Based eHealth Data Analysis
摘要
The Internet of Things has integrated seamlessly woven itself into different aspects of our lives, playing a crucial role in sectors such as security, transportation, smart homes, and healthcare. Within these areas, Internet of Things utilizes various sensors to generate substantial amounts of data, which are traditionally stored in centralized systems like Cloud Computing. However, this method brings about challenges, including high latency, response times, and security issues during data processing and analysis. To address these challenges, federated learning a groundbreaking branch of artificial intelligence has emerged. This new paradigm enables machine learning techniques to leverage decentralized data and computing power, primarily found in edge devices, ensuring a personalized user experience without compromising privacy. In this article, we propose a Federated CNN Model Based on Knowledge Distillation (MD_CNN) that clients train local models on private datasets, then share model weights with a central server, which uses these models for labeling and training a global model. Using the UCI-HAR dataset, achieving an accuracy of 83.46%, a precision of 83.62%, a recall of 83.46%, an AUC of 93.46%, and a loss of 1.23.
