Sparse additive function decompositions facing basis transforms
High-dimensional real-world systems can often be well characterized by a small number of
simultaneous low-complexity interactions. The analysis of variance (ANOVA) decomposition …

ANOVA-boosting for Random Fourier Features
D Potts, L Weidensager - arXiv preprint arXiv:2404.03050, 2024 - arxiv.org
We propose two algorithms for boosting random Fourier feature models for approximating
high-dimensional functions. These methods utilize the classical and generalized analysis of …

Learning Sparse Mixture Models
FA Ba - arXiv preprint arXiv:2203.15615, 2022 - arxiv.org
This work approximates high-dimensional density functions with an ANOVA-like sparse
structure by the mixture of wrapped Gaussian and von Mises distributions. When the …
