WebWe show that typical implicit regularization assumptions for deep neural networks (for regression) do not hold for coordinate-MLPs, a family of MLPs that are now ubiquitous in computer vision for representing high-frequency signals.
WebAs a remedy, recent studies empirically confirmed that projecting the coordinates to a higher di-mensional space using sine and cosine functions of different frequencies (i.e., … 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.
