a Ground state wavefunctions from the gapless \({{\mathbb{Z}}}_{2}\) phase and ferromagnetically ordered phase are obtained at the points on the J-axis marked by stars. The highlighted box shows the two most informative filters for the classification task. The pink and blue dots in filters correspond to projections in z and y basis. b The regularization path analysis results pointing to the filters in panel a as signature motifs of the ordered phase.
