Deep learning (DL) models have driven advancements in AI and machine learning but face challenges such as interpretability, susceptibility to adversarial attacks, dependency on pre-trained networks, and high computational demands. These limitations hinder their deployment on mobile and edge devices.

Chee-An Yu, inspired by the concept of Green AI/ML (GL) introduced by Kuo, focuses on developing energy-efficient, mathematically transparent models with small sizes and low complexity. These models excel in limited-data scenarios and are suitable for both cloud and edge environments. The current project explores GL methods to learn RF signatures for detecting jamming signals and reconstructing the original signal using the Green U-Shape Learning (GUSL) pipeline.[1-3]

Initial applications of GL in wireless communications have shown promise, with efficient performance in few-shot learning tasks and reduced computational requirements.
