    • Estimating Dependency Structure as a Hidden Variable 

      Meila, Marina; Jordan, Michael I.; Morris, Quaid (1997-06-01)
      This paper introduces a probability model, the mixture of trees that can account for sparse, dynamically changing dependence relationships. We present a family of efficient algorithms that use EMand the Minimum Spanning ...

    • Translation Invariance in Object Recognition, and Its Relation to Other Visual Transformations 

      Dill, Marcus; Edelman, Shimon (1997-06-01)
      Human object recognition is generally considered to tolerate changes of the stimulus position in the visual field. A number of recent studies, however, have cast doubt on the completeness of translation invariance. In a ...

    • Perceiving Illumination Inconsistencies in Scenes 

      Ostrovsky, Yuri; Cavanagh, Patrick; Sinha, Pawan (2001-11-05)
      The human visual system is adept at detecting and encoding statistical regularities in its spatio-temporal environment. Here we report an unexpected failure of this ability in the context of perceiving inconsistencies in ...
