High order and sparse layers in pytorch. Lagrange Polynomial, Piecewise Lagrange Polynomial, Piecewise Discontinuous Lagrange Polynomial (Chebyshev nodes) and Fourier Series layers of arbitrary order.

💡 Throwback to a small Python project I worked on a month ago! I created a program that computes Lagrange interpolation polynomials using SymPy. It takes a set of points, calculates each Lagrange ...

Abstract: In this article, we investigate the application of Lagrange polynomials for compressing data vectors within the context of constrained model predictive control (MPC). Lagrange polynomials, ...
