Learning to solve multiresolution matrix factorization by manifold optimization and evolutionary metaheuristics

open access: yesMachine Learning: Science and Technology
Multiresolution matrix factorization (MMF) is unusual amongst fast matrix factorization algorithms in that it does not make a low rank assumption. This makes MMF especially well suited to modeling certain types of graphs with complex multiscale or ...

Haar-LikeWavelets over Tetrahedra

open access: yesJournal of Computer Science and Technology, 2017
In this paper we define a Haar-like wavelets basis that form a basis for L2(T,S,μ), μ being the Lebesgue measure and S the σ -algebra of all tetrahedra generated from a subdivision method of the T tetrahedron.

Unraveling the Relationship Between Nr4a2 and Fezf1 Expression in the Developing Feline Telencephalon Within the Genoarchitectonic Context of Claustral and Amygdalar Development

open access: yesJournal of Comparative Neurology, Volume 534, Issue 11, November 2026.
To define the emergence of the claustral complex in relation to the expression patterns of Nr4a2 and Fezf1 in the domestic cat, a species with more protracted prenatal development than the mouse, we performed a genoarchitectonic analysis. Nr4a2 marked differentiating claustral neurons within the LPall mantle, whereas Fezf1 was broadly expressed in the ...

Multiresolution Analysis and Radon Measures on a Locally Compact Abelian Group [PDF]

open access: yes, 2001
summary:A multiresolution analysis is defined in a class of locally compact abelian groups $G$. It is shown that the spaces of integrable functions $\mathcal L^p(G)$ and the complex Radon measures $M(G)$ admit a simple characterization in terms of this ...

Continuous Wavelet Decompositions, Multiresolution, and Contrast Analysis

open access: yes, 1993
International audienceA continuous version of multiresolution analysis is described, starting from usual continuous wavelet decompositions. Scale discretization leads to decompositions into functions of arbitrary bandwidth, satisfying QMF-like conditions.

Unsupervised texture segmentation using multiresolution Markov random fields [PDF]

open access: yes
In this thesis, a multiresolution Markov Random Field (MMRF) model for segmenting textured images without supervision is proposed. Stochastic relaxation labelling is adopted to assign the class label with highest probability to the block (site) being ...

Multiresolution Mesh Representation: Models and Data Structures

open access: yes, 2002
Multiresolution meshes are a common basis for building representations of a geometric shape at dierent levels of detail. The use of the term multiresolution depends on the remark that the accuracy (or, level of detail) of a mesh in approximating a shape

Adaptive Wavelet Thresholding for Multiresolution Denoising Based on Image Size

open access: yesEngineering Proceedings
Hard thresholding is a common method for denoising wavelet coefficients. However, determining an optimal threshold remains challenging. Therefore, we propose an adaptive hard threshold that accounts for the size of the noisy image based on the ...
