Datasets

Datasets#

All datasets are subclasses of tonic.datasets.Dataset and need certain methods implemented: __init__, __getitem__ and __len__. This design is inspired by torchvision’s way to provide datasets.

Events for a sample in both audio and vision datasets are output as structured numpy arrays of shape (N,E), where N is the number of events and E is the number of event channels. Vision events typically have 4 event channels: time, x and y pixel coordinates and polarity, whereas audio events typically have time, x and polarity.
