Fig. 4From: Effect of APOE ε4 on multimodal brain connectomic traits: a persistent homology studyThe statistical performance of different regularization parameters. For 0-dimensional features and 1-dimensional features, the candidate parameters for grid search are sampling number Nλ1 and regularization parameter λ2. For other graph theory measurements, the candidate parameters are regularization parameter λ1 and λ2Back to article page
