Researchers propose 'computational identifiability,' a new framework that redefines how causal effects are identified in data science by shifting from theoretical, infinite-data assumptions to practical, finite computational search procedures. This approach enables identification under realistic conditions including small samples, ambiguous graphical criteria, and mixed observational-interventional data.
Researchers demonstrate that Information Lattice Learning (ILL), a technique for discovering interpretable rules in signals, naturally aligns with probabilistic graphical model structure learning when applied to probability distributions.
