In a chance constrained program (CCP), decision makers seek the best whose probability of violating uncertainty constraints is within prespecified risk level. As CCP often nonconvex and difficult to solve optimality, much effort has been devoted developing convex inner approximations for CCP, among which conditional value-at-risk ([Formula: see text]) known be more than decade. This paper studi...

Student engagement is a key component of learning and teaching, resulting in plethora automated methods to measure it. Whereas most the literature explores student analysis using computer-based often lab, we focus on classroom instruction authentic environments. We collected audiovisual recordings secondary school classes over one half month period, acquired continuous labeling per (N=15) repea...
