Physics-Informed Neural Networks for coupled stiff transport systems
Laetitia Laguzet, Gabriel Turinici
Physics-Informed Neural Networks (PINN) struggle with stiff, regime-changing transport equations due to instability, loss imbalance, and violations of physical consistency. This pa…

Model free collision aggregation for the computation of escape distributions
Laetitia Laguzet, Gabriel Turinici
Motivated by a heat radiative transport equation, we consider a particle undergoing collisions in a space-time domain and propose a method to sample its escape time, space and dire…

The Quantization Monte Carlo method for solving radiative transport equations
Laetitia Laguzet, Gabriel Turinici
We introduce the Quantization Monte Carlo method to solve thermal radiative transport equations with possibly several collision regimes, ranging from few collisions to massive numb…
