  • Semi-parametric Functional Classification via Path Signatures Logistic Regression

    Semi-parametric Functional Classification via Path Signatures Logistic Regression arXiv:2507.06637v1 Announce Type: new Abstract: We propose Path Signatures Logistic Regression (PSLR), a semi-parametric framework for classifying vector-valued functional data with scalar covariates. Classical functional logistic regression models rely on linear assumptions and fixed basis expansions, which limit flexibility and degrade performance under irregular sampling. PSLR overcomes…

  • Communities in the Kuramoto Model: Dynamics and Detection via Path Signatures

    Communities in the Kuramoto Model: Dynamics and Detection via Path Signatures arXiv:2503.17546v1 Announce Type: new Abstract: The behavior of multivariate dynamical processes is often governed by underlying structural connections that relate the components of the system. For example, brain activity which is often measured via time series is determined by an underlying structural graph, where…
