WaGI : Wavelet-based GAN Inversion for Preserving High-frequency Image Details

no code implementations18 Oct 2022 Seung-Jun Moon, Chaewon Kim, Gyeong-Moon Park

Especially, we prove that the widely-used loss term in GAN inversion, i. e., L2, is biased to reconstruct low-frequency features mainly.

Zero-shot Blind Image Denoising via Implicit Neural Representations

no code implementations5 Apr 2022 Chaewon Kim, Jaeho Lee, Jinwoo Shin

Recent denoising algorithms based on the "blind-spot" strategy show impressive blind image denoising performances, without utilizing any external dataset.

Scaling Neural Tangent Kernels via Sketching and Random Features

1 code implementation NeurIPS 2021 Amir Zandieh, Insu Han, Haim Avron, Neta Shoham, Chaewon Kim, Jinwoo Shin

To accelerate learning with NTK, we design a near input-sparsity time approximation algorithm for NTK, by sketching the polynomial expansions of arc-cosine kernels: our sketch for the convolutional counterpart of NTK (CNTK) can transform any image using a linear runtime in the number of pixels.

Random Features for the Neural Tangent Kernel

no code implementations3 Apr 2021 Insu Han, Haim Avron, Neta Shoham, Chaewon Kim, Jinwoo Shin

We combine random features of the arc-cosine kernels with a sketching-based algorithm which can run in linear with respect to both the number of data points and input dimension.
