264 : Delta RNN and Leaky Integrate-and-Fire Nueron Circuit
- Author: Katherine Rogacheva
- Description: A physical representation of a delta recurrent neural network (Delta RNN) and a leaky integrate-and-fire (LIF) neuron, that creates an artificial spike when the difference in the previous and current state is greater than a set delta threshold.
- GitHub repository
- Clock: 0 Hz
How it works
Takes inputput voltages and treats that as the input current injection into the LIF neuron
