What happened

Collection of new arXiv ML/STAT papers (2026-07-02) covering theory and methods: (1) Fourier Neural Operators — approximation and polynomial sample-complexity guarantees for time-T solution operators of dissipative PDEs (incl. Navier–Stokes) via spectral-discretization assumptions; (2) neural estimation of time-varying AR(p) parameters with uncertainty quantification under Gaussian and Laplace noise; (3) hierarchical variational Kalman filtering — surrogate state for explicit process-noise inference and faster, single-step hyperparameter fitting; (4) deep multitask learning with unknown monot0
