To compare mathematical formalizations for quantifying consciousness, contrasting Integrated Information Theory (IIT 4.0) with an algorithmic information theory framework.
Evaluated the standard IIT 4.0 formulation calculating integrated information (Φ) via minimum information partitions and Earth Mover's Distance over cause-effect structures.
Formulated an alternative metric (Φ_AIT) utilizing Kolmogorov complexity to evaluate integrated information across partitioned state spaces.
IIT 4.0 models consciousness as irreducible cause-effect power using directed acyclic graphs of distinctions and relations quantified by Earth Mover's Distance.
The algorithmic information approach formalizes integrated information as Φ_AIT = K(X) − Σ K(X_i), avoiding lossy integration inherent in partition-based entropy sums.
