Mixed Jacobi-Fourier spectral method for Fisher equation
Mathematical Modelling and Analysis, 2018 In this paper, we propose a mixed Jacobi-Fourier spectral method for solving the Fisher equation in a disc. Some mixed Jacobi-Fourier approximation results are established, which play important roles in numerical simulation of various problems defined in ...

Eliminating Nonuniform Smearing and Suppressing the Gibbs Effect on Reconstructed Images
Computers, 2020 In this work, the problem of eliminating a nonuniform rectilinear smearing of an image is considered, using a mathematical- and computer-based approach. An example of such a problem is a picture of several cars, moving with different speeds, taken with a

A SPECTRAL METHOD FOR DECONVOLVING A DENSITY [PDF]
Econometric Theory, 2010 We propose a new estimator for the density of a random variable observed with an additive measurement error. This estimator is based on the spectral decomposition of the convolution operator, which is compact for an appropriate choice of reference spaces.

Spectral methods for matrices and tensors [PDF]
Proceedings of the forty-second ACM symposium on Theory of computing, 2010 While Spectral Methods have long been used for Principal Component Analysis, this survey focusses on work over the last 15 years with three salient features: (i) Spectral methods are useful not only for numerical problems, but also discrete optimization problems (Constraint Optimization Problems - CSP's) like the max.

The Spectral Underpinning of word2vec
Frontiers in Applied Mathematics and Statistics, 2020 Word2vec introduced by Mikolov et al. is a word embedding method that is widely used in natural language processing. Despite its success and frequent use, a strong theoretical justification is still lacking.
