The reasoning is primarily perceptual and only secondarily symbolic. In the past decade, we have built several imagistic reasoners that perform at an expert level on scientific problems that defy current analytical methods, including helping us solve open problems. We hypothesize that much of scientific reasoning is imagistic and that this reasoning is best automated by imagistic algorithms. The classical artificial intelligence architecture Âa central deductive reasoner operating on symbolic predicates delivered by low-level perceptual preprocessors Âis unsuitable for these tasks. Imagistic reasoners are faster and more efficient because they trade many inferences for sensing and action. Their behavior is easier to understand and debug because they deal directly with geometric structures and their interactions. Imagistic reasoning organizes comaround information-rich, putations analogue representations of physical systems.
