Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

  • Closingmethod0.809
    Dynamic condition: ending a branch or closing a frame.
  • Itemsets (attribute subsets) that are both frequent (large extent) and closed; same as intents of concepts with large extent.
  • Patch-Closureconcept0.736
    A set property meaning all coordinate patches of its elements remain within the set; proved equivalent to axis-aligned hyperrectangles
  • Method used with Andre and Anna: standing on site with eyes closed, abandoning preconceptions, visualizing the most comfortable remembered place
  • Functional closureconcept0.719
    The property of a subsystem that cannot influence others; used to lesion systems in simulations.
  • Feedback-based coupling between neural cultures and robots/virtual environments.
  • A hypothesized intermediate-level linearly-represented feature (e.g., Beijing and China are closely associated) that may correlate with truth in unnegated datasets but anti-correlate in negated ones
  • Efficient algorithm for computing all closed sets (intents or extents) in lectic order without storing exponential lists.
