What Are Brain-Inspired AI Models?

Brain-inspired AI models, also known as neuromorphic computing systems, are computational frameworks designed to emulate the structure and functionality of biological neural networks. Unlike traditional AI systems that rely on binary logic and sequential processing, these models replicate the parallel and distributed nature of the human brain. They use specialized hardware, such as spiking neural networks (SNNs) and neuromorphic chips, to process information in a way that mimics synaptic activity. This approach enables faster, more energy-efficient computations and adaptive learning capabilities.
