LAPLEX enables trainable Laplace kernels for high-dimensional deep learning

Researchers have introduced LAPLEX, a novel class of learnable Laplace-kernel operators designed to enable efficient, high-dimensional linear algebra in deep learning. LAPLEX layers act like full-rank dense matrices but are implicitly defined by a small set of learnable parameters, allowing for matrix-vector operations at scales up to $10^9$ dimensions on GPUs. This approach separates the expressivity of dense matrices from their storage cost, facilitating data-adaptive global interactions and enabling compact projections and interpretable soft routing models.

    LAPLEX: The FFT of Learnable Laplace Kernels

    arXiv:2605.24584v1 Announce Type: cross Abstract: Fast linear algebra in deep learning usually comes with a choice: fixed geometry and exact computation, as in the Fourier transform, or adaptive geometry paid for by dense parameters, random features, or low-rank surrogates. To mo…
