Abstract
Attribution of attention from observable body posture is plausible, providing additional information for affective computing applications. We previously reported a promissory $69.72\pm10.50$ ($\mu\pm \sigma$) of F-measure to use posture as a proxy for attributed attentional state with implications for affective computing applications. Here, we aim at improving that classification rate by reweighting votes of raters giving higher confidence to those raters that are representative of the raters population. An increase to $75.35\pm11.66$ in F-measure was achieved. The improvement in predictive power by the classifier is welcomed and its impact is still being assessed.
