Problems such as this, where model parameters (the location of the activity) have to be estimated from measured data (the SQUID signals) are referred to as inverse problems (in contrast to forward problems [11] where the model parameters (e.g. source location) are known and the data (e.g. the field at a given distance) is to be estimated.)
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.
Inverse inference, the inverse of normal inference, is a critical concept of inferential confusion.A person starts out believing in the truthfulness of a theory even though evidence suggests otherwise creating uncertainty about an actual state causing distress.
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
The inverse of the above Weyl map is the Wigner map (or Wigner transform), which was introduced by Eugene Wigner, [9] which takes the operator Φ back to the original phase-space kernel function f, f ( q , p ) = 2 ∫ − ∞ ∞ d y e − 2 i p y / ℏ q + y | Φ [ f ] | q − y . {\displaystyle f(q,p)=2\int _{-\infty }^{\infty }{\text{d}}y~e ...
It follows that, given two frames, there is exactly one homography mapping the first one onto the second one. In particular, the only homography fixing the points of a frame is the identity map. This result is much more difficult in synthetic geometry (where projective spaces are defined through axioms).

For the logistic map with r = 4.5, trajectories starting from almost any point in [0, 1] go towards minus infinity. When the parameter r exceeds 4, the vertex r /4 of the logistic map graph exceeds 1. To the extent that the graph penetrates 1, trajectories can escape [0, 1].
