Multi-dimensional concept discovery (MCD): A unifying framework with completeness guarantees

Understand

The completeness axiom renders the explanation of a post-hoc XAI method only locally faithful to the model, i.e.

• for a single decision.
• For the trustworthy application of XAI, in particular for high-stake decisions, a more global model understanding is required.
• Recently, concept-based methods have been proposed, which are however not guaranteed to be bound to the actual model reasoning.
