Structure learning for directed trees

WebIn this paper, we consider structure learning of directed trees. We propose a fast and scalable method based on Chu–Liu–Edmonds’ algorithm we call causal additive trees (CAT). For the case of Gaussian errors, we prove consistency in an asymptotic regime with a vanishing identifiability gap. WebAug 19, 2024 · In this paper, we consider structure learning of directed trees.

ENCO … WebFour tree-based structure learning methods are implemented with graph and data-driven algorithms. The graph methods refer to the fast Steiner Tree (ST) Kou's algorithm, and the identification of the Minimum Spanning Tree (MST) with Prim's algorithm. The data-driven methods propose fast and scalable procedures based on WebKnowing the causal structure of a system is of fundamental interest in many areas of science and can aid the design of prediction algorithms that work well under manipulations to the system. The causal structure becomes identifiable from the observational distribution under certain restrictions. To learn the structure from data, score-based methods … mark veitch furniture
