Abstract

With the rapid advancements in mobile sensing and computing technology, there is a surge of innovative intelligent applications that monitor and manage our daily lives ubiquitously. Traditional mobile sensing/computing applications used to collect user information locally and transmit data to a more powerful server for intelligent data processing operations. However, more recent developments showcase a shift towards a more localized and personalized approach. This involves processing data collected locally on user devices, enhancing efficiency, and prioritizing privacy. This presentation will delve into the applications driving this paradigm shift, bringing intelligence from the cloud to user devices. Additionally, we will explore novel machine learning frameworks supporting localized intelligence experiences. This includes introducing mechanisms to reduce model complexity, enabling memory-efficient on-device model training, and facilitating efficient federated learning.
