New methods advance triangular transport maps for probabilistic modeling · 2 sources tracked

Researchers have developed new methods for learning triangular transport maps, which are crucial for probabilistic modeling tasks like density estimation and generative modeling. The first paper introduces Self-Structuring Transport Maps (SSTM) that jointly learn the map, variable ordering, and sparsity pattern, improving density estimates compared to methods that estimate structure first. The second paper presents multifidelity approaches to construct these maps when high-fidelity data is scarce, leveraging lower-fidelity data through hierarchical or corrective strategies to enhance map estimation and downstream simulation-based inference.

    Multifidelity Formulations for Triangular Transport

    arXiv:2610.00698v1 Announce Type: cross Abstract: We develop multifidelity methods for constructing triangular transport maps from samples, when high-fidelity data are scarce but lower-fidelity data are more abundant. Using this set of multifidelity data, we approximate a triangu…
