Research Paper
Core Innovation
This paper introduces Time-step Mixup knowledge transfer (TMKT), which leverages asynchronous spiking neural network dynamics to interpolate RGB and event data at multiple time-steps. It also proposes modality-aware auxiliary objectives to enable effective label mixing across modalities, addressing the distribution gap between RGB and event data. This results in smoother knowledge transfer and improved classification performance compared to prior methods that overlook modality shifts.
