Abstract

We present a computational framework capable of labelingthe effort of an action corresponding to the perceivedlevel of exertion by the performer (low - high). The approachinitially factorizes examples (at different efforts) ofan action into its three-mode principal components to reducethe dimensionality. Then a learning phase is introducedto compute expressive-feature weights to adjust themodel's estimation of effort to conform to given perceptuallabels for the examples. Experiments are demonstrated recognizingthe efforts of a person carrying bags of differentweight and for multiple people walking at different paces.
