arXiv:2605.29411v1 Announce Type: new Abstract: Under standard graphical assumptions, the Markov boundary of a target variable is the smallest set of features that renders every other feature redundant. Once the boundary is observed, the target is conditionally independent of the rest of the table. This is a tempting object for tabular prediction, since it names exactly the columns a model should need. Yet modern regressors are still trained on the full feature set. We ask whether the Markov boundary is genuinely useful for prediction on SCM3K, a 3,450-task synthetic SCM benchmark with feature
The paper is published as part of ongoing research in machine learning, specifically exploring fundamental architectural choices that influence efficiency and interpretability of AI models.
This research explores a core theoretical concept that could significantly improve the efficiency of tabular data prediction, a pervasive task across industries.
It questions the established practice of training models on full feature sets, suggesting potential for more parsimonious and equally effective models if Markov boundaries can be practically leveraged.
