Cluster-Based Generalized Additive Models Informed by Random Fourier Features
Researchers have developed a new algorithm for learning mixture models that can handle heavy-tailed distributions, a significant improvement over previous methods that relied on low-degree moments. This novel approach utilizes efficient high-dimensional sparse Fourier transforms and does not require a minimum separation between cluster means, unlike algorithms for Gaussian mixtures. Additionally, a separate study introduces a regression framework that combines spectral representation learning with localized additive modeling to create interpretable models for heterogeneous data.
