Small-Shot Multi-Modal Distillation for Vision-Based Autonomous Steering

In this paper, we propose a novel learning frame- work for autonomous systems that uses a small amount of “auxiliary information” that complements the learning of the main modality, called “small-shot auxiliary modality distillation network (AMD-S-Net)”. The AMD-S-Net contains a two-stream framework design that can fully extract information from dif- ferent types of data (i.e., paired/unpaired multi-modality data) to distill knowledge more effectively. We also propose a novel training paradigm based on the “reset operation” that enables the teacher to explore the local loss landscape near the student domain iteratively, providing local landscape information and potential directions to discover better solutions by the student, thus achieving higher learning performance. Our experiments show that AMD-S-Net and our training paradigm outperform other SOTA methods by up to 12.7% and 18.1% improvement in autonomous steering, respectively.
