PF-ViT: Parallel and Fast Vision Transformer for Offline Handwritten Chinese Character Recognition. [PDF]

open access: yesComput Intell Neurosci, 2022
Recently, Vision Transformer (ViT) has been widely used in the field of image recognition. Unfortunately, the ViT model repeatedly stacks 12‐layer encoders, resulting in a large number of model computations, many parameters, and slow training speed, making it difficult to deploy on mobile devices.

Willingness to pay for credence attributes associated with agri‐food products—Evidence from Canada

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, Volume 71, Issue 3-4, Page 303-327, September-November 2023., 2023
Abstract Credence attributes such as environmental impact, origin, fairness/unfairness, and food safety/health are not available with certainty prior to or at the time of the consumer purchase decision. This creates a problem of imperfect or asymmetric information, leading to suboptimal supply and demand for products with these desirable attributes ...

Laguerre–Freud equations for three families of hypergeometric discrete orthogonal polynomials

open access: yesStudies in Applied Mathematics, Volume 151, Issue 2, Page 509-535, August 2023., 2023
Abstract The Cholesky factorization of the moment matrix is considered for discrete orthogonal polynomials of hypergeometric type. We derive the Laguerre–Freud equations when the first moments of the weights are given by the 1F2, 2F2, and 3F2 generalized hypergeometric series.

Parameter and q asymptotics of Lq‐norms of hypergeometric orthogonal polynomials

open access: yesInternational Journal of Quantum Chemistry, Volume 123, Issue 2, January 15, 2023., 2023
The weighted Lq‐norms of orthogonal polynomials are determined when q and the polynomial's parameter tend to infinity. They are given in this work by the leading term of the q and parameter asymptotics of the corresponding quantities of the associated probability density. These results are not only interesting per se, but also because they control many

Consumer willingness to pay for healthier food products: A systematic review

open access: yesObesity Reviews, Volume 24, Issue 1, January 2023., 2023
Summary Food retail strategies to improve the healthiness of food and beverage options may increase purchasing of healthier options and improve diets. Consumer demand for healthier options is an important determinant of the successful implementation and maintenance of healthy food retail interventions.

Comparison of discrete transforms for deep‐neural‐networks‐based speech enhancement

open access: yesIET Signal Processing, Volume 16, Issue 4, Page 438-448, June 2022., 2022
Abstract In recent studies of speech enhancement, a deep‐learning model is trained to predict clean speech spectra from the known noisy spectra of speech. Rather than using the traditional discrete Fourier transform (DFT), this paper considers other well‐known transforms to generate the speech spectra for deep‐learning‐based speech enhancement.

Pearson equations for discrete orthogonal polynomials: I. Generalized hypergeometric functions and Toda equations

open access: yesStudies in Applied Mathematics, Volume 148, Issue 3, Page 1141-1179, April 2022., 2022
Abstract The Cholesky factorization of the moment matrix is applied to discrete orthogonal polynomials on the homogeneous lattice. In particular, semiclassical discrete orthogonal polynomials, which are built in terms of a discrete Pearson equation, are studied.

Exceptional Hahn and Jacobi polynomials with an arbitrary number of continuous parameters

open access: yesStudies in Applied Mathematics, Volume 148, Issue 2, Page 606-650, February 2022., 2022
Abstract We construct new examples of exceptional Hahn and Jacobi polynomials. Exceptional polynomials are orthogonal polynomials with respect to a measure which are also eigenfunctions of a second‐order difference or differential operator. In mathematical physics, they allow the explicit computation of bound states of rational extensions of classical ...

Facial Recognition of Cattle Based on SK‐ResNet

open access: yesScientific Programming, Volume 2022, Issue 1, 2022., 2022
With the gradual increase of the scale of the breeding industry in recent years, the intelligence level of livestock breeding is also improving. Intelligent breeding is of great significance to the identification of livestock individuals. In this paper, the cattle face images are obtained from different angles to generate the cow face dataset, and a ...

On Perfectness of Systems of Weights Satisfying Pearson’s Equation with Nonstandard Parameters

open access: yesAxioms, 2023
Measures generating classical orthogonal polynomials are determined by Pearson’s equation, whose parameters usually provide the positivity of the measures.
