  • Supervised Quadratic Feature Analysis: An Information Geometry Approach to Dimensionality Reduction

    Supervised Quadratic Feature Analysis: An Information Geometry Approach to Dimensionality Reduction arXiv:2502.00168v1 Announce Type: new Abstract: Supervised dimensionality reduction aims to map labeled data to a low-dimensional feature space while maximizing class discriminability. Despite the availability of methods for learning complex non-linear features (e.g. Deep Learning), there is an enduring demand for dimensionality reduction methods…

  • A dimensionality reduction technique based on the Gromov-Wasserstein distance

    A dimensionality reduction technique based on the Gromov-Wasserstein distance arXiv:2501.13732v1 Announce Type: new Abstract: Analyzing relationships between objects is a pivotal problem within data science. In this context, Dimensionality reduction (DR) techniques are employed to generate smaller and more manageable data representations. This paper proposes a new method for dimensionality reduction, based on optimal transportation…
