I see this too, just missing Classification on p106
Scholar.Metrics.Classification.accuracy(test_targets, test_preds)
Similarly on p107 with confusion_matrix/3, it is also missing the Classification:
Scholar.Metrics.Classification.confusion_matrix(test_targets, test_preds, num_classes: 3
p110
Scholar.Metrics.Classification.accuracy(test_targets, test_preds)
Scholar.Metrics.Classification.confusion_matrix(test_targets, test_preds, num_classes: 3
