A hybrid approach for solving the gravitational N-body problem with Artificial Neural Networks

Veronica Saz Ulibarrena, Philipp Horn, Simon Portegies Zwart +3

Simulating the evolution of the gravitational N-body problem becomes extremely computationally expensive as N increases since the problem complexity scales quadratically with the n…

Comparison of neural closure models for discretised PDEs

Hugo Melchers, Daan Crommelin, Barry Koren +2

Neural closure models have recently been proposed as a method for efficiently approximating small scales in multiscale systems with neural networks. The choice of loss function and…

On the influence of stochastic roundoff errors and their bias on the convergence of the gradient descent method with low-precision floating-point computation

Lu Xia, Stefano Massei, Michiel E. Hochstenbach +1

When implementing the gradient descent method in low precision, the employment of stochastic rounding schemes helps to prevent stagnation of convergence caused by the vanishing gra…

Improved stochastic rounding

Lu Xia, Martijn Anthonissen, Michiel Hochstenbach +1

Due to the limited number of bits in floating-point or fixed-point arithmetic, rounding is a necessary step in many computations. Although rounding methods can be tailored for diff…
