Explainer Principles

PyXAI includes a module Explainer which provides different methods for explaining decisions made by ML models.

The Concepts page explains:

  • How to initialize this module (Explainer.initialize and <Explainer Object>.set_instance)
  • The concepts on which it is based (mainly the binary representation of an instance)
  • How to display an explanation (<Explainer Object>.to_features)

The other pages within this section present several miscellaneous features:

  • Theories are representation of pieces of knowledge about the dataset. PyXAI offers the possibility of encoding a theory calculating explanations in order to avoid the computation of impossible explanations.
  • The Explainer offers the possibility to process user preferences (prefer some explanations to others and exclude some features): Preferences
  • How to use a time limit when calculating explanations ? Time Limit

Several kinds of explanations can be computed according to the properties they hold (direct, sufficient, majoritary, tree-specific, contrastive):

To finish the Visualization Of Explanations page present the PyXAI’s Graphical User Interface (GUI).
