Machine Learning

The Wolfram Language includes a wide range of integrated machine learning capabilities, from highly automated functions like Predict and Classify to functions based on specific methods and diagnostics. The functions work on many types of data, including numerical, categorical, time series, textual, and image.


General Supervised Learning

Classify classify data into categories using a built-in classifier or learning from examples

ClassifierFunction symbolic representation of a classifier to be applied to data

Predict predict values from data using a built-in predictor or learning from examples

PredictorFunction symbolic representation of a predictor to be applied to data

ClassifierMeasurements, PredictorMeasurements performance on test data

ClassifierInformation, PredictorInformation model information etc.
