When Noise meets Chaos: Stochastic Resonance in Neurochaos Learning
This work is an incremental step towards understanding the role of noise and chaos in brain-inspired AI learning architectures.
This paper explores Stochastic Resonance (SR) in Neurochaos Learning (NL), demonstrating that intermediate noise levels enhance subthreshold signal detection in single neurons and improve classification performance on simulated and real-world spoken digit datasets.
Chaos and Noise are ubiquitous in the Brain. Inspired by the chaotic firing of neurons and the constructive role of noise in neuronal models, we for the first time connect chaos, noise and learning. In this paper, we demonstrate Stochastic Resonance (SR) phenomenon in Neurochaos Learning (NL). SR manifests at the level of a single neuron of NL and enables efficient subthreshold signal detection. Furthermore, SR is shown to occur in single and multiple neuronal NL architecture for classification tasks - both on simulated and real-world spoken digit datasets. Intermediate levels of noise in neurochaos learning enables peak performance in classification tasks thus highlighting the role of SR in AI applications, especially in brain inspired learning architectures.
