Teaching Neural Networks Where Errors Matter | Newswise
[ad_1] Newswise — This study introduces volume weighting physics-informed neural networks (VW-PINNs), a new framework that changes how residual errors are evaluated during training. By weighting the PDE residual according to the volume occupied by collocation points in the computational domain, the method avoids over-learning in regions where collocation points are densely sampled. A sufficient […]
KATRIN Narrows Down the Range of Neutrinos’ Mass
[ad_1] The Science Scientists have known about the existence of neutrinos – tiny fundamental particles that almost never interact with matter – for 95 years. Nobel Prize-winning work in 1998 showed that their mass is not zero. However, neutrinos’ exact mass is still unknown. The international KArlsruhe TRItium Neutrino (KATRIN) experiment uses the process by which a […]
When Neutron Stars Collide, Neutrinos Change Flavors
[ad_1] The Science Newswise — Neutron stars are among the densest objects in the universe. They are packed so tightly that a spoonful of their matter weighs more than a mountain. When two neutron stars collide, they release huge numbers of tiny particles called neutrinos. Neutrinos are fundamental particles that come in three types, or “flavors.” These […]
