Classification and clustering of participants based on the similarity of gaze patterns. A Correctly classified and misclassified participants across cross-validation iterations of a Gaussian Naive Bayes classifier. Color bar encodes the frequency at which an individual participant was classified correctly. Participants denoted by square (diamond) markers were correctly classified (misclassified) more than 75% of the time across iterations. Participants shown with pentagon markers were classified with a frequency lower than 75% (i.e., confused as autistic or TD control in different iterations). Red-yellow (dark-light blue) spectrum colors depict autistic (TD control) participants. The four-dimensional gaze features space used to build the classifier was projected onto a two-dimensional t-SNE space here for visualization purposes only. B Unsupervised clustering of participants into subgroups using a Gaussian mixture model procedure. The clustering procedure automatically identified two groups of participants (indicated as Cluster 1 and 2). Color bar encodes the frequency at which an individual participant was assigned to Cluster 1. Participants denoted by right- (up-) pointing triangle markers were assigned to Cluster 1 (Cluster 2) more than 75% of the time across iterations. Participants shown with hexagon markers were assigned with a frequency lower than 75% (i.e., confused as Cluster 1 or 2 in different iterations)
