A, Multiclass classification differentiating AP, non-AP, and non-musicians based on whole-brain functional networks: Null distribution of accuracies with permuted group labels (left) and recursive feature elimination outcome (right). B, Confusion matrix of classifier performance (accuracy) for multiclass classification. C, Classification of AP versus non-AP musicians: Null distribution of accuracies with permuted group labels (left) and recursive feature elimination outcome (right). D, Classification of non-AP versus non-musicians: Null distribution of accuracies with permuted group labels (left) and recursive feature elimination outcome (right).
