Neural Network

A neural network is a computing system inspired by biological neural networks in the brain, consisting of interconnected nodes called neurons that process and transmit information through weighted connections. Each neuron receives inputs, applies mathematical transformations, and produces outputs that feed into subsequent layers. Neural networks learn by adjusting the weights of these connections during training, allowing them to optimize their performance on specific tasks. Deep neural networks with many layers have proven exceptionally effective at learning complex patterns in data, powering modern AI applications from image recognition to natural language processing. Example: The transformer architecture underlying GPT models and modern LLMs uses multi-headed attention mechanisms with billions of neural network parameters to process and generate text sequences. Why it matters for AI and data in Web3: Neural networks enable blockchain analysis, price prediction models, and on-chain anomaly detection, though their computational requirements create challenges for privacy-preserving applications and decentralized ML execution in resource-constrained environments.
