Abstract

Recently there has been an increase in efforts in BehavioralSignal Processing (BSP), that aims to bring quantitative analysis usingsignal processing techniques in the domain of observational coding.Currently observational coding in fields such as psychology is based onsubjective expert coding of abstract human interaction dynamics. In thiswork, we use a Multiple Instance Learning (MIL) framework, a saliencybasedprediction model, with a signal-driven vocal entrainment measureas the feature to predict the affective state of a spouse in problem solvinginteractions. We generate 18 MIL classifiers to capture the variablelengthsaliency of vocal entrainment, and a cross-validation scheme withmaximum accuracy and mutual information as the metric to select thebest performing classifier for each testing couple. This method obtains arecognition accuracy of 53.93%, a 2.14% (4.13% relative) improvementover baseline model using Support Vector Machine. Furthermore, thisMIL-based framework has potential for identifying meaningful regions ofinterest for further detailed analysis of married couples interactions.
