Hierarchical wasserstein alignment

WebIn many machine learning applications, it is necessary to meaningfully aggregate, through alignment, different but related datasets. Optimal transport (OT)-based approaches pose alignment as a divergence minimization problem: the aim is to transform a source dataset to match a target dataset using the Wasserstein distance as a divergence measure … Web2 de jun. de 2024 · The main contributions of our work are as follows: To the best of our knowledge, the proposed Hierarchical Triple-level Alignment (HTA) approach is the first attempt to simultaneously model three types of information, i.e., domain labels, class labels, and data structures, in a unified framework for UMDA.
