Title

"An Engineer's Foray into Topological Learning: Addressing Challenges in Mobile Robot Perception and Mapping"

Abstract

Topological learning (TL), referring to a synergy of computational topology and machine learning, has recently emerged as an effective pattern recognition framework for noisy, high-dimensional problems. The recognition happens by first identifying the topological structures that encode the shape and connectedness information among the observations (sample), and then characterizing the structures based on their relative persistence over a wide range of spatial and/or temporal scales. In this talk, I discuss successful demonstrations of TL for challenging mobile robot perception and mapping problems in unseen environments. Our novel adaptation of TL recognizes occluded objects and anomalies significantly more accurately than other state-of-the-art shape or learning-based methods without requiring real-world training samples. I conclude by pointing out future research directions for active multi-robot coordination.
