Spike-based output

Definition

Spike-based output refers to a communication method in neural networks where information is conveyed through discrete spikes or action potentials rather than continuous signals. This approach mimics biological neural systems, where neurons fire spikes at specific times to represent data, allowing for efficient processing and transmission of auditory information, especially in the design of artificial auditory systems like silicon cochleas.
