cosine ≥ 0.65 · no typed edgeEntities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.
- 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.
- 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
- 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.
