Bongard and Smirnov on the tetrachromacy of extra-foveal vision.
In Moscow in the 1950's, the physicist M. M. Bongard developed the use of silent substitution to establish the number of dimensions of human or animal colour vision and to derive colour-matching functions either for whole...
Data driven regularization by projection
Abstract: We study linear inverse problems under the premise that the forward operator is not at hand but given indirectly through some input-output training pairs. We demonstrate that regularization by projection and...
Two-layer neural networks with values in a Banach space
Yury Korolev
Dec 31, 2022
We study two-layer neural networks whose domain and range are Banach spaces with separable preduals. In addition, we assume that the image space is equipped with a partial order, i.e. it is a Riesz space. As the nonlinearity we...

Magnetoelectric doubling and mixing of electric and magnetic field frequencies in a layered multiferroic heterostructure
Nonlinear magnetoelectric effects in a disk-like heterostructure composed of a layer of amorphous ferromagnet (FeBSiC) mechanically coupled to a layer of piezoelectric ceramics (lead zirconate titanate) were studied both...

Near-instant automatic access to visually presented words in the human neocortex
Rapid and efficient processing of external information by the brain is vital to survival in a highly dynamic environment. The key channel humans use to exchange information is language, but the neural underpinnings of its...
Ultra-rapid access to words in the brain.
Rapid information processing in the human brain is vital to survival in a highly dynamic environment. The key tool humans use to exchange information is spoken language, but the exact speed of the neuronal mechanisms...

Variational regularisation for inverse problems with imperfect forward operators and general noise models.
Leon Bungert, martin.burger@fau.de, Martin Burger, Yury Korolev, Carola-Bibiane Schönlieb
Jul 28, 2021
We study variational regularisation methods for inverse problems with imperfect forward operators whose errors can be modelled by order intervals in a partial order of a Banach lattice. We carry out analysis with respect to...

Neural dynamics of inflectional and derivational processing in spoken word comprehension
Rapid and automatic processing of grammatical complexity is argued to take place during speech comprehension, engaging a left-lateralized fronto-temporal language network. Here we address how neural activity in these regions is...

Nov 21, 2019
Effects of intensive language action therapy (ILAT) on automatic language processing were assessed using Magnetoencephalography (MEG). Auditory magnetic mismatch negativity (MMNm) responses to words and pseudowords were recorded...

Previous studies have demonstrated that efficient neurorehabilitation in post stroke aphasia leads to clinical language improvements and promotes neuroplasticity. Brain areas frequently implicated in functional restitution of...
