Uniform-Certificate Bayesian Feature Head

Replace the final layer of a neural predictor with Bayesian linear regression over deterministic trigonometric features, retaining a computable posterior variance and a high-probability confidence envelope over the full bounded input domain. Use this envelope to reject unsafe actions, downweight uncertain training targets, or restrict optimizer updates in regions where the network is extrapolating.

Epoch-Frozen Masked Low-Rank Candidate Encoder

Add an online low-rank reconstruction layer before a recommender or ranking MLP. It estimates a latent action-feature subspace from masked candidate vectors, freezes that subspace for an epoch, reconstructs each partially observed candidate in the latent coordinates, and feeds only those coordinates to the predictor. The method is most promising when the ambient candidate dimension d is large but the effective rank m is small and missingness is not too severe.
