SIAM journal on imaging sciences

Mang A, Biros G.
PMID: 29075361
SIAM J Imaging Sci. 2016;9(3):1154-1194. doi: 10.1137/15M1010919. Epub 2016 Aug 30.

We propose regularization schemes for deformable registration and efficient algorithms for their numerical approximation. We treat image registration as a variational optimal control problem. The deformation map is parametrized by its velocity. Tikhonov regularization ensures well-posedness. Our scheme augments...

With the advent of the Heliophysics/Geospace System Observatory (H/GSO), a complement of multi-spacecraft missions and ground-based observatories to study the space environment, data retrieval, analysis, and visualization of space physics data can be daunting. The Space Physics Environment Data...

Regulation of GluA1 phosphorylation by d-amphetamine and methylphenidate in the cerebellum.

Addiction biology

Cutando L, Puighermanal E, Castell L, Tarot P, Bertaso F, Bonnavion P, de Kerchove d'Exaerde A, Isingrini E, Galante M, Dallerac G, Pascoli V, Lüscher C, Giros B, Valjent E.

Prescription stimulants, such as d-amphetamine or methylphenidate are used to treat suffering from attention-deficit hyperactivity disorder (ADHD). They potently release dopamine (DA) and norepinephrine (NE) and cause phosphorylation of the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunit GluA1 in the striatum....

IEEE Trans Pattern Anal Mach Intell. 2021 May 28; doi: 10.1109/TPAMI.2021.3084839. Epub 2021 May 28.

In this paper, we compress convolutional neural network (CNN) weights post-training via transform quantization. Previous CNN quantization techniques tend to ignore the joint statistics of weights and activations, producing sub-optimal CNN performance at a given quantization bit-rate, or consider...
