WebFourier frequency mapping) allows coordinate-MLPs to learn high-frequency informa-tion more effectively [19,38]. This observation was recently characterized theoretically by Tancik et al. [34], showing that the above projection permits tuning the spectrum of the neural tangent kernel (NTK) of the corresponding MLP, thereby enabling the Web1 de fev. de 2024 · The key difference between coordinate-MLPs and regular MLPs is that the former is designed to encode signals with higher frequencies – mitigating the spectral bias of the latter – via specific architectural modifications. Below, we will succinctly discuss three types of coordinate-MLPs.
