The prediction of response tensors from magnetic textures is a crucial challenge in the study of noncollinear magnets. Existing methods for constructing descriptors of a given response tensor are limited to first-order multipole expansions or restricted to simple magnetic structures. In this work, we construct a complete symmetry-invariant descriptor basis for arbitrary crystal structures and magnetic textures, providing interpretable features for machine learning modeling of response tensors. We modify the standard principal component analysis framework and derive uncorrelated order parameters that are hierarchically stable: extending the order parameter space to include higher-degree spin order introduces additional order parameters that are uncorrelated to the previous ones. We apply this framework to regression and classification of the anomalous Hall conductivity (AHC) in a magnetic kagome lattice. In particular, in the regime where AHC is well modeled by linear regression of the symmetry-invariant order parameters, we find that the squared regression coefficients, ranked by their magnitude, obey a Zipf-like power law: βᵣ² ∝ r^(-α). Our method provides a systematic route to construct interpretable order parameters of all spin orders that connect the symmetry of a magnetic crystal to its response tensors.
