In 1944, psychologists Fritz Heider and Marianne Simmel created a short, 90-second animated film depicting two triangles and a circle moving around a box with a hinged opening, and reported how subjects viewing the film anthropomorphized the three shapes as characters with humanlike goals, emotions, and social relationships. In this talk, I will describe our efforts to model this type of high-level reasoning as a process of probability-ordered logical abduction (Etcetera Abduction), where the interpretation of the film is incrementally constructed by disambiguating observed movements in the contexts of multiple running hypotheses. I'll discuss how this type of knowledge-based reasoning can be paired with low-level perception systems and natural language generation systems, and contrast the approach with recent trends involving deep neural networks.
