Estimator types

This section lists the various object types (scitypes) available in sktime.

sktime supports unified interfaces for different types of algorithms and objects. These are internally referred to as scitypes, with strict string identifiers such as "forecaster", "classifier", "detector", etc.

Each object type corresponds to a specific unified interface and base class. Every object in sktime has one or more scitypes, which can be inspected via its "object_type" tag.

For a list of all tags, see Object and estimator tags.
