romtools.workflows.inverse.vi_sample_reuse

Importance-sampling sample reuse for VI and MFVI.

This module implements an opt-in ABRIS-style reuse layer around ROMTools’ existing VI drivers. Expensive high-fidelity evaluations are cached in batches together with the variational distribution that generated them. A bounded inner sampling loop adds fresh batches until the reuse diagnostics pass, then forms the update from the complete retained archive.

Functions

mf_vi_with_auto_rom(*args[, sample_reuse_config])	Auto-ROM MFVI wrapper with the same sample-reuse configuration.
run_mf_vi(*args[, sample_reuse_config])	Run MFVI with optional importance-sampling reuse of the HF archive.
run_vi(*args[, sample_reuse_config])	Run VI, optionally reusing historical model evaluations through MIS.
