New method Learnable Spectral Activations improves neural network representations

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced Learnable Spectral Activations (LSA), a novel approach to implicit neural representations (INRs). LSA replaces fixed nonlinearities with a residual truncated Fourier series, allowing harmonic amplitudes to be learned during training. This method refines the factorization of representations by separating linear weight selection from spectral shaping, leading to improved optimization and reconstruction quality across various tasks including audio, image, and neural fields. AI

IMPACT This research could lead to more efficient and effective neural network training and reconstruction across various domains.

    Learnable Spectral Activations

    arXiv:2610.07419v1 Announce Type: new Abstract: Implicit neural representations (INRs) are shaped by the spectral structure induced by their input encodings and activation functions. Existing methods improve fitting primarily by modifying which frequencies are available to the ne…
