Neural Networks

Definition

Neural networks are a subset of machine learning models designed to recognize patterns by mimicking the way human brains operate. They consist of interconnected nodes, or neurons, that process data in layers, transforming input information into an output that can be used for decision-making. Their ability to learn from large amounts of data makes them especially valuable for predictive analytics and automation in various applications, including early warning systems for environmental threats.
