pyphi.measures.ces.ces_distance(C1, C2, measure=None, *, system=None)[source]#

Return the distance between two cause-effect structures.

Dispatches to the registered CES measure named by measure and rounds the result to config.numerics.precision.

Parameters:

  • C1 (Distinctions) – The first Distinctions.

  • C2 (Distinctions) – The second Distinctions.

  • measure (str, optional) – Which registered CES measure to use. If None, defaults to config.formalism.iit.ces_measure.

  • system (System, optional) – The system the CESs were computed over. Required by measures that operate on full repertoires (e.g. EMD); ignored by purely phi-summing measures (e.g. SUM_SMALL_PHI).

Returns:

float – The distance between the two cause-effect structures.

Return type:

float
