Fig. 4: Prediction results of Cognitive age by 2 optimal models: SVM and kNN.
From: A new cognitive clock matching phenotypic and epigenetic ages
Panel rows corresponds to optimal models: SVM (a, b) and kNN (c, d). Left column (a, c): prediction of chronological age by models for train and test samples; black line corresponds to the diagonal of the first quarter. Right column (b, d): distribution of age deviations of Cognitive clock. Test set selected as the first 20% of the dataset and train set as the remaining subjects. Such partitions were used only for visualization.
