The ECE Ph.D. candidate won the Best Poster award at the 2023 IBM IEEE AI Compute Symposium.
The award-winning poster, titled “Towards Bit Error Robust Energy-Efficient Autonomous Systems”, presents a cross-layer robust learning framework aimed at achieving aggressive energy-saving yet computational-resilient autonomous swarms.
The research tackles the challenges of the distributed resource-constrained nodes, complex cyber-physical autonomous systems and increased chip bit failures, by proposing innovative approaches including robust offline/on-device learning, collaborative swarm optimizations, and dynamic thermal-payload adjustments.
Applied across hardware chips, swarm systems, and various autonomous scenarios, the technique demonstrates consistent performance-efficiency-robustness improvements for multi-drone systems.
This acclaimed research is a product of a collaborative effort between Georgia Tech, IBM Research, Harvard University, and Lawrence Livermore National Laboratory (LLNL). The work is supported in part by the Center for the Co-Design of Cognitive Systems (CoCoSys), the IAPRA MicroE4AI program, and the Center for Research into Novel Compute Hierarchies (CRNCH) PhD Fellowship.
