    "title": "Learning and Generalizing Cross-Category Relations\nUsing Hierarchical Distributed Representations",
    "subtitle": null,
    "abstract": "Recent work has begun to investigate how structured relations\ncan be learned from non-relational and distributed input\nrepresentations. A difficult challenge is to capture the human\nability to evaluate relations between items drawn from distinct\ncategories (e.g., deciding whether a truck is larger than a\nhorse), given that different features may be relevant to\nassessing the relation for different categories. We describe an\nextension of Bayesian Analogy with Relational\nTransformations (BART; Lu, Chen & Holyoak, 2012) that\ncan learn cross-category comparative relations from\nautonomously-generated and distributed input representations.\nBART first learns separate representations of a relation for\ndifferent categories and creates second-order features based\non these category-specific representations. BART then learns\nweights on these second-order features, resulting in a\ncategory-general representation of the relation. This\nhierarchical learning model successfully generalizes the\nrelation to novel pairs of items (including items from different\ncategories), outperforming a flat version of the learning\nmodel.",
