  2. Generalized Poincaré conjecture - Wikipedia

    en.wikipedia.org/wiki/Generalized_Poincaré...

    The generalized Poincaré conjecture is true topologically, but false smoothly in most dimensions. In fact, for odd dimensions, the smooth Poincaré conjecture is only true in dimensions 1, 3, 5 and 61. In even dimensions it is known that the smooth Poincaré conjecture is true in dimensions 2, 6, 12 and 56.

    The full generalization rule allows for hypotheses to the left of the turnstile, but with restrictions.Assume is a set of formulas, a formula, and () has been derived. The generalization rule states that () can be derived if is not mentioned in and does not occur in .

  4. Occurs check - Wikipedia

    en.wikipedia.org/wiki/Occurs_check

    Prolog implementations usually omit the occurs check for reasons of efficiency, which can lead to circular data structures and looping. By not performing the occurs check, the worst case complexity of unifying a term with term is reduced in many cases from (() + ()) to (((), ())); in the particular, frequent case of variable-term unifications, runtime shrinks to ().

  6. Existential generalization - Wikipedia

    en.wikipedia.org/wiki/Existential_generalization

    In predicate logic, existential generalization [1] [2] (also known as existential introduction, ∃I) is a valid rule of inference that allows one to move from a specific statement, or one instance, to a quantified generalized statement, or existential proposition.

  7. General regression neural network - Wikipedia

    en.wikipedia.org/wiki/General_regression_neural...

    [1] GRNN can be used for regression, prediction, and classification. GRNN can also be a good solution for online dynamical systems. GRNN represents an improved technique in the neural networks based on the nonparametric regression. The idea is that every training sample will represent a mean to a radial basis neuron. [2]

  8. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    Numeric literals in Python are of the normal sort, e.g. 0, -1, 3.4, 3.5e-8. Python has arbitrary-length integers and automatically increases their storage size as necessary. Prior to Python 3, there were two kinds of integral numbers: traditional fixed size integers and "long" integers of arbitrary size.

  9. Burzio's generalization - Wikipedia

    en.wikipedia.org/wiki/Burzio's_generalization

    In generative linguistics, Burzio's generalization is the observation that a verb can assign a theta role (a title used to describe the relationship between the noun phrase and the predicate, such as agent, theme, and goal) to its subject position if and only if it can assign an accusative case to its object. Accordingly, if a verb does not ...
