3D MRI brain tumor segmentation using autoencoder regularization

BrainLes@MICCAI, 2018
Automated segmentation of brain tumors from 3D magnetic resonance images (MRIs) is necessary for the diagnosis, monitoring, and treatment planning of the disease.

Regular Rings are Very Regular

Canadian Mathematical Bulletin, 1982
The following problem arose in a conversation with Abraham Zaks: “Suppose R is an associative ring with identity such that every finitely generated left ideal is generated by idempotents. Is R von-Neumann regular?” In the literature the “s” in “idempotents” is missing, and is replaced by “an idempotent”. The answer is, “Yes!”

Regular Categories and Regular Functors

Canadian Journal of Mathematics, 1974
Let be a category with nice factorization-properties. If a functor G: —> which has a left-adjoint behaves nice with respect to factorizations then it can be shown quite easily that G behaves well in many other respects, especially that it lifts nice properties from into .

Spectral regularization and minEnt regularization

IEEE International Conference on Acoustics Speech and Signal Processing, 2002
In this paper, we propose the spectral regularization based on the conventional (spatial) regularization and the Fourier analysis. The entropy regularization is further developed and its connection to MinEnt principle is investigated. The underlying geometrical, physical and biological interpretation of spectral and entropic regularization are ...

Zeta Regularizations

Acta Applicandae Mathematica, 2004
This is an informal survey on various results concerning zeta regularization. The authors put special emphasis on examples of which they give many. These examples are of interest to geometry or number theory.

Implicit Regularization in Matrix Factorization

Information Theory and Applications Workshop, 2017
We study implicit regularization when optimizing an underdetermined quadratic objective over a matrix $X$ with gradient descent on a factorization of X.

Otolith regularities

Hearing Research, 2000
The masses and the area sizes of the otoliths for the utriculus, sacculus and lagena of 15 species of the Black Sea fish are analyzed. Morphometrical otolith regularities are derived and their functional and ecomorphological explanations are suggested.

REGULAR SEMIHYPERGROUPS

Russian Academy of Sciences. Sbornik Mathematics, 1993
Let \(G\) be a locally compact Hausdorff space, \(\varepsilon_ x\) a probability measure concentrated in the point \(x\in G\), \({\mathfrak A}\) be the algebra of all finite measures on \(G\) with respect to the convolution \(*\). A semihypergroup \((G,*)\) is called a regular semihypergroup if a) There exists a two-sided neutral element \(\varepsilon_

How regular is regular? An analysis of menstrual cycle regularity

Contraception, 2004
We performed a retrospective analysis to ascertain how accurately women who believe that they have regular menstrual cycles estimate the length of their actual cycles. Data were extracted from a chart review of subjects from three different studies of barrier contraceptives.
