ILearner interface

This article describes iLearner, which is the interface for trained models that is used in Azure Machine Learning Studio (classic).


Applies to: Machine Learning Studio (classic)

This content pertains only to Studio (classic). Similar drag and drop modules have been added to Azure Machine Learning designer (preview). Learn more in this article comparing the two versions.

The ILearner interface provides methods and properties that are used to configure and interact with machine learning models. A learner is defined as a set of instructions that perform standardized machine learning tasks. Learners include classification algorithms, clustering algorithms, and regression algorithms.

You can interact with iLearner only in Studio (classic), or in one of the supported APIs.

Studio (classic) uses this interface for the following functionality:

  • Determines whether a model has the correct format.
  • Gets the capabilities of the learner. These are any general properties of the learner that are not captured by the type signature of the specific learner.
  • Gets or sets the settings of the learner.The settings are unique to each learner and must be configured once before any query methods can be called on the learner.

For a list of learners provided by Azure Machine Learning Studio (classic), see Initialize Model.


The ICluster interface is also available, for clustering models only.
