Query: EvDistill: Asynchronous Events to End-task Learning via Bidirectional
  Reconstruction-guided Cross-modal Knowledge Distillation   Event cameras sense per-pixel intensity changes and produce asynchronous
event streams with high dynamic range and less motion blur, showing advantages
over conventional cameras. A hurdle of training event-based models is the lack
of large qualitative labeled data. Prior works learning end-tasks mostly rely
on labeled or pseudo-labeled datasets obtained from the active pixel sensor
(APS) frames; however, such datasets' quality is far from rivaling those based
on the canonical images. In this paper, we propose a novel approach, called
\textbf{EvDistill}, to learn a student network on the unlabeled and unpaired
event data (target modality) via knowledge distillation (KD) from a teacher
network trained with large-scale, labeled image data (source modality). To
enable KD across the unpaired modalities, we first propose a bidirectional
modality reconstruction (BMR) module to bridge both modalities and
simultaneously exploit them to distill knowledge via the crafted pairs, causing
no extra computation in the inference. The BMR is improved by the end-tasks and
KD losses in an end-to-end manner. Second, we leverage the structural
similarities of both modalities and adapt the knowledge by matching their
distributions. Moreover, as most prior feature KD methods are uni-modality and
less applicable to our problem, we propose to leverage an affinity graph KD
loss to boost the distillation. Our extensive experiments on semantic
segmentation and object recognition demonstrate that EvDistill achieves
significantly better results than the prior works and KD with only events and
APS frames.
