To implement our designs, we turn to single-photon sensors that provide digital access to individual photon detections; this modality gives us the flexibility to realize a rich space of generalized event cameras.

As an added benefit, our projections provide camera-dependent compression of photon-cubes, which we demonstrate using an implementation of our projections on a novel compute architecture that is designed for single-photon imaging.

For a fixed parameter count and compute budget, the proposed algorithm (RigL) claims to directly train sparse networks that match or exceed the performance of existing denseto-sparse training techniques (such as pruning).
