Machine learning

Description

G06N20/00 is the main group for machine learning, i.e. computing arrangements in which behaviour is derived from training data rather than fixed programming. It spans supervised, unsupervised and reinforcement learning workflows, including model training, validation and inference infrastructure. Kernel methods such as support vector machines are classified in G06N20/10 and ensemble techniques such as boosting or random forests in G06N20/20. Neural-network models as such belong to G06N3/00, and the application of learned models to pattern recognition tasks is covered by G06F18/00.
