From: Support vector machine prediction of individual Autism Diagnostic Observation Schedule (ADOS) scores based on neural responses during live eye-to-eye contact

Figure 3

The relationship between the behavioral measure of social symptom severity, ADOS score (X axis), and the predicted ADOS score based on the SVM classification (Y axis), is determined by the brain activity during the live eye to eye condition (A) and during the video eye to eye condition (B). Increasing ADOS scores indicate increasing symptomatology. Numbers on the scatter plot indicate the individual participants with ASD (see Supplementary Table 1). In Fig. 3 all of the participants are clinically diagnosed with ASD, the red and blue numbers indicate correct and incorrect SVM classifications, respectively. The correlation between observed and predicted, r, is 0.72 for the eye-to-eye condition (A) and 0.14 for the video watching condition (B). In the eye-to-eye condition (A) 4 out of 17 participants with ASD were incorrectly classified as TD, and 12 of the 17 participants were misclassified in the video condition (B). To simplify comparison between SVM scores and ADOS scores, we used a linear transform on SVM scores to provide a comparable value for visualization.
