  2. Reverse correlation technique - Wikipedia

    en.wikipedia.org/wiki/Reverse_correlation_technique

    The reverse correlation technique is a data driven study method used primarily in psychological and neurophysiological research. [1] This method earned its name from its origins in neurophysiology, where cross-correlations between white noise stimuli and sparsely occurring neuronal spikes could be computed quicker when only computing it for segments preceding the spikes.

  3. Repertory grid - Wikipedia

    en.wikipedia.org/wiki/Repertory_grid

    The repertory grid is a technique for identifying the ways that a person construes (interprets or gives meaning to) his or her experience. [4] It provides information from which inferences about personality can be made, but it is not a personality test in the conventional sense.

  4. Inverse mapping theorem - Wikipedia

    en.wikipedia.org/wiki/Inverse_mapping_theorem

    In mathematics, inverse mapping theorem may refer to: the inverse function theorem on the existence of local inverses for functions with non-singular derivatives the bounded inverse theorem on the boundedness of the inverse for invertible bounded linear operators on Banach spaces

  5. Inversive geometry - Wikipedia

    en.wikipedia.org/wiki/Inversive_geometry

    P ' is the inverse of P with respect to the circle. To invert a number in arithmetic usually means to take its reciprocal. A closely related idea in geometry is that of "inverting" a point. In the plane, the inverse of a point P with respect to a reference circle (Ø) with center O and radius r is a point P ', lying on the ray from O through P ...

  6. Conformal geometric algebra - Wikipedia

    The point x = 0 in R p,q maps to n o in R p+1,q+1, so n o is identified as the (representation) vector of the point at the origin. A vector in R p+1,q+1 with a nonzero n ∞ coefficient, but a zero n o coefficient, must (considering the inverse map) be the image of an infinite vector in R p,q.

  9. Involution (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Involution_(mathematics)

    Any involution is a bijection.. The identity map is a trivial example of an involution. Examples of nontrivial involutions include negation (x ↦ −x), reciprocation (x ↦ 1/x), and complex conjugation (z ↦ z) in arithmetic; reflection, half-turn rotation, and circle inversion in geometry; complementation in set theory; and reciprocal ciphers such as the ROT13 transformation and the ...
