Spike inference with cascade
WebSpike inference with CASCADE A--ool and a large ground truth dataset enable spike inference from calcium imaging data acquired in a variety of experimental c. C alcium imaging in the brain WebSpiking neural networks (SNNs) are inspired by information processing in biology, where sparse and asynchronous binary signals are communicated and processed in a massively parallel fashion. SNNs on neuromorphic hardware exhibit favorable properties such as low power consumption, fast inference, and event-driven information processing. This makes …
