Convergence theory for Hermite approximations under adaptive coordinate transformations

Yahya Saleh

Recent work has shown that parameterizing and optimizing coordinate transformations using normalizing flows, i.e., invertible neural networks, can significantly accelerate the conv…

Enhancing polynomial approximation of continuous functions by composition with homeomorphisms

Álvaro Fernández Corral, Yahya Saleh

We enhance the approximation capabilities of algebraic polynomials by composing them with homeomorphisms. This composition yields families of functions that remain dense in the spa…

Transferability and interpretability of vibrational normalizing-flow coordinates

Emil Vogt, Álvaro Fernández Corral, Yahya Saleh +1

The choice of vibrational coordinates is crucial for the accuracy, efficiency, and interpretability of molecular vibrational dynamics and spectra calculations. We explore the recen…

Taylor-mode automatic differentiation for constructing molecular rovibrational Hamiltonian operators

Andrey Yachmenev, Emil Vogt, Álvaro Fernández Corral +1

We present an automated framework for constructing Taylor series expansions of rovibrational kinetic and potential energy operators for arbitrary molecules, internal coordinate sys…
