  "summary": "AdaPS-LiNGAM replaces DirectLiNGAM's sequential residualization, which degenerates when variables exceed sample size, by reconstructing each residual from a sparse 'active boundary' subset of already-ordered variables and applying the same subset selection to edge pruning. It costs only classical CPU-based statistics (sparse regression, no GPU), but adds subset-selection complexity and hyperparameter sensitivity. It can fail under non-linear or non-Gaussian-violating data, latent confounding, and its gains are demonstrated only on synthetic benchmarks.",
