Modified least squares method and a review of its applications in machine learning and fractional differential/integral equations

Abhishek Kumar Singh, Mani Mehra, Anatoly A. Alikhanov

The least squares method provides the best-fit curve by minimizing the total squares error. In this work, we provide the modified least squares method based on the fractional ortho…

A computational macroscale model for the time fractional poroelasticity problem in fractured and heterogeneous media

Aleksei Tyrylgin, Maria Vasilyeva, Anatoly Alikhanov +1

In this work, we introduce a time memory formalism in poroelasticity model that couples the pressure and displacement. We assume this multiphysics process occurs in multicontinuum…

A second order difference scheme for time fractional diffusion equation with generalized memory kernel

Aslanbek Khibiev, Anatoly Alikhanov, Chengming Huang

In the current work we build a difference analog of the Caputo fractional derivative with generalized memory kernel (L2-1 formula). The fundamental features of this differe…

About one method of parallelization of calculations during the reconstruction of a tomographic image

A. A. Alikhanov, A. M. Apekov, Z. A. Kokov +2

A new method for solving systems of linear algebraic equations of a special type arising in solving problems of image reconstruction has been proposed. This method, due to a certai…
