Potential function of gradient
Web25 Apr 2024 · Integrating the force gradient once and twice elucidates the values of the interaction force and the interatomic potential, respectively. However, getting the frequency shift as a function of the force gradient requires a physical model which can describe the equations of motion properly. Most papers have adopted the single harmonic oscillator ... WebPotential-Function Proofs for First-Order Methods Nikhil Bansaly Anupam Guptaz June 4, 2024 Abstract This technical note discusses proofs of convergence for rst-order methods based on simple potential-function arguments. We cover methods like gradient descent (for both smooth and non-smooth settings), mirror descent, and some accelerated variants.
