Monotone Forced-Response Adapter

Separate a pretrained sequence model's passive prediction from the causal effect of an action, and learn only the latter with a compact monotone adapter. The adapter receives the current latent state and an action deviation, but its action-to-output Jacobian is constrained to have the physically correct sign, preventing intervention predictions that move opposite to the applied control.

Jin–Xin shock homotopy for PINNs

Train on a sequence of Jin–Xin relaxation problems with decreasing relaxation width rather than training immediately on the singular conservation law. The network predicts both the conserved state and an auxiliary flux, and each stage is initialized from the previous stage so that the learned shock profile sharpens gradually.
