Researchers have developed new methods for optimal transportation and Gromov-Wasserstein alignment specifically for Gaussian distributions. These techniques offer interpretable geometric frameworks for comparing and transforming heterogeneous datasets, which are common in machine learning. The work provides analytical solutions for uncentered Gaussian measures and extends to an analytic solution for the inner product Gromov-Wasserstein barycenter between centered Gaussians. The researchers demonstrated the utility of these methods by comparing embeddings of language model distillations and clustering synthetic user data based on text embedding covariance spectra. AI
