Abstract: |
To gauge whether a tower of objects will fall, are visual heuristics sufficient? In this study, we explore the potential of pattern recognition as a viable model of intuitive physical inference in a task that requires observers to estimate the stability of stacked building blocks, comparing the performance of a deep feedforward convolutional neural network to human performance using psychophysics. In analyzing human and machine behavior alike, we identify a pair of image-based visual features that strongly predict both human and machine performance and differ only in the summary statistic used to compute them. Our results suggest that a system trained only to recognize patterns in visual input and given no explicit physical knowledge (e.g. mass, gravity, friction or elasticity) is nonetheless capable of approximating human judgments in a paradigmatic intuitive physics task. |
