    "title": "A Computational Model for Learning Structured Concepts From Physical Scenes",
    "subtitle": null,
    "abstract": "Category learning is an essential cognitive mechanism for\nmaking sense of the world. Many existing computational category\nlearning models focus on categories that can be represented\nas feature vectors, and yet a substantial part of the categories\nwe encounter have members with inner structure and\ninner relationships. We present a novel computational model\nthat perceives and learns structured concepts from physical\nscenes. The perception and learning processes happen simultaneously\nand interact with each other. We apply the model\nto a set of physical categorization tasks and promote specific\ntypes of comparisons by manipulating presentation order of\nexamples. We find that these manipulations affect the algorithm\nsimilarly to human participants that worked on the same\ntask. Both benefit from juxtaposing examples of different categories\n– especially ones that are similar to each other. When\njuxtaposing examples from the same category they do better if\nthe examples are dissimilar to each other.",
