Deep Learning: Neural Networks

Introduction to Neural Networks

Neural Networks, a cornerstone of deep learning, are computational models inspired by the structure and function of the human brain. They are designed to recognize patterns and relationships in data, enabling them to perform complex tasks like image recognition, natural language processing, and predictive analytics.

At their core, neural networks consist of interconnected nodes, or "neurons," organized in layers. These layers process information, progressively extracting higher-level features from the input data. The learning process involves adjusting the strengths of connections between neurons to minimize errors and improve accuracy.
