- Authors: Taewon Kang, Soohyun Kim, Sunwoo Kim, Seungryong Kim
- Abstract summary: Existing techniques to solve exemplar-based image-to-image translation within deep convolutional neural networks (CNNs) generally require a training phase to optimize the network parameters.
We propose a novel framework, for the first time, to solve exemplar-based translation through an online optimization given an input image pair.
Our framework does not require the off-line training phase, which has been the main challenge of existing methods, but the pre-trained networks to enable optimization in online.

- Abstract: Existing techniques to solve exemplar-based image-to-image translation within
deep convolutional neural networks (CNNs) generally require a training phase to
optimize the network parameters on domain-specific and task-specific
benchmarks, thus having limited applicability and generalization ability. In
this paper, we propose a novel framework, for the first time, to solve
exemplar-based translation through an online optimization given an input image
pair, called online exemplar fine-tuning (OEFT), in which we fine-tune the
off-the-shelf and general-purpose networks to the input image pair themselves.
We design two sub-networks, namely correspondence fine-tuning and multiple GAN
inversion, and optimize these network parameters and latent codes, starting
from the pre-trained ones, with well-defined loss functions. Our framework does
not require the off-line training phase, which has been the main challenge of
existing methods, but the pre-trained networks to enable optimization in
online. Experimental results prove that our framework is effective in having a
generalization power to unseen image pairs and clearly even outperforms the
state-of-the-arts needing the intensive training phase.

deep equilibrium model is a class of models that foregoes traditional network depth and instead computes the output of a network by finding the fixed point of a single nonlinear layer.
We show that there is a natural synergy between these two settings.
We demonstrate this strategy on various tasks such as training generative models while optimizing over latent codes, training models for inverse problems like denoising and inpainting, adversarial training and gradient based meta-learning.
