Deep learning

Definition

Deep learning is a subset of machine learning that utilizes neural networks with many layers to analyze various forms of data. It mimics the way the human brain processes information, enabling systems to learn from vast amounts of unstructured data, such as images and text. This technique is essential in discovering complex patterns and relationships within datasets, making it particularly valuable in fields like chemical kinetics for predicting reaction rates and modeling molecular interactions.
