Interstellar collision rates without fresh quantum scattering: neural networks fill 18 systems to 500 K and guess unseen CS and CF+
Feed-forward neural networks trained on state-to-state rate coefficients for 24 linear molecules colliding with para-H2 extend existing datasets to 500 K and 696 cm-1 and give a first estimate within a factor of 3 for CS and CF+, which were excluded from training entirely.
