Neural networks are complex interconnected nodes inspired by the human brain's ability to learn and adapt, crucial for modern AI systems.
They consist of layers of interconnected neurons where each neuron processes inputs and sends outputs, allowing the network to learn complex patterns in data.
Neural networks learn through backpropagation, adjusting connections to optimize performance on tasks, with various types and applications across industries.
While facing challenges, neural networks revolutionize AI, integrated into AWS services and algorithms to create sophisticated systems improving industries and lives.
