Overview

NR-GAN: Noise Robust Generative Adversarial Networks (CVPR 2020)

This repository provides PyTorch implementation for noise robust GAN (NR-GAN). NR-GAN is unique in that it can learn a clean image generator even when only noisy images are available for training.

NR-GAN examples

Note: In our previous studies, we have also proposed GANs for label noise. Please check them from the links below.

Paper

Noise Robust Generative Adversarial Networks. Takuhiro Kaneko and Tatsuya Harada. In CVPR, 2020.

[Paper] [Project] [Slides] [Video]

Installation

Clone this repo:

git clone https://github.com/takuhirok/NR-GAN.git
cd NR-GAN/

First, install Python 3+. Then install PyTorch 1.3 and other dependencies by the following:

pip install -r requirements.txt

Training

To train a model, use the following script:

bash ./scripts/train.sh [dataset] [model] [output_directory_path]

Example

To train SI-NR-GAN-I (sinrgan1) on CIFAR-10 with additive Gaussian noise with a fixed standard deviation (cifar10ag25), run the following:

bash ./scripts/train.sh cifar10ag25 sinrgan1 outputs

The results are saved into outputs.

Note: In our experiments, we report the best model encountered during training to mitigate the performance fluctuation caused by GAN training instability.

Options

Regarding [dataset], choose one option among the following:

  • cifar10: No noise
  • cifar10ag25: (A) Additive Gaussian noise with a fixed standard deviation
  • cifar10ag5-50: (B) Additive Gaussian noise with a variable standard deviation
  • cifar10lg25p16: (C) Local Gaussian noise with a fixed-size patch
  • cifar10lg25p8-24: (D) Local Gaussian noise with a variable-size patch
  • cifar10u50: (E) Uniform noise
  • cifar10mix: (F) Mixture noise
  • cifar10bg25k5: (G) Brown Gaussian noise
  • cifar10abg25k5: (H) Sum of (A) and (G)
  • cifar10mg25: (I) Multiplicative Gaussian noise with a fixed standard deviation
  • cifar10mg5-50: (J) Multiplicative Gaussian noise with a variable standard deviation
  • cifar10amg5_25: (K) Sum of few (A) and (I)
  • cifar10amg25_25: (L) Sum of much (A) and (I)
  • cifar10p30: (M) Poisson noise with a fixed total number of events
  • cifar10p10-50: (N) Poisson noise with a variable total number of events
  • cifar10pg30_5: (O) Sum of (M) and few (A)
  • cifar10pg30_25: (P) Sum of (M) and much (A)

Noise examples

Regarding [model], choose one option among the following:

  • gan: GAN
  • ambientgan: AmbientGAN
  • sinrgan1: SI-NR-GAN-I
  • sinrgan2: SI-NR-GAN-II
  • sdnrgan1: SD-NR-GAN-I
  • sdnrgan2: SD-NR-GAN-II
  • sdnrgan3: SD-NR-GAN-III

Examples of generated images

CIFAR-10 with additive Gaussian noise

cifar10ag25: (A) Additive Gaussian noise with a fixed standard deviation

Examples of generated images on CIFAR-10 with additive Gaussian noise

AmbientGAN is trained with the ground-truth noise model, while the other models are trained without full knowledge of the noise (i.e., the noise distribution type and noise amount).

CIFAR-10 with multiplicative Gaussian noise

cifar10mg25: (I) Multiplicative Gaussian noise with a fixed standard deviation

Examples of generated images on CIFAR-10 with multiplicative Gaussian noise

AmbientGAN is trained with the ground-truth noise model, while the other models are trained without full knowledge of the noise (i.e., the noise distribution type, noise amount, and signal-noise relationship).

  • A question about one

    A question about one "OPTION" in your shell scripts

    Set up model

    case ${MODEL} in "gan" ) ;; "ambientgan" ) OPTION="${OPTION} --noise_measure" ;; "sinrgan1" ) OPTION="${OPTION} --prior additive_gaussian" ;; "sinrgan2" ) OPTION="${OPTION} --gn_train --rotation --channel_shuffle --color_inversion" ;; "sdnrgan1" ) OPTION="${OPTION} --gn_train --prior ${PRIOR}" ;; "sdnrgan2" ) OPTION="${OPTION} --gn_train --implicit --prior additive_gaussian" ;; "sdnrgan3" ) OPTION="${OPTION} --gn_train --implicit --color_inversion" ;; * ) echo "unknown MODEL: ${MODEL}" exit 1 ;; esac

    I read your paper, an excellent work which inspires me a lot. However, when I view your source code, I have a question about one "OPTION" in your shell scripts. As shown above, in the case of "sinrgan1", OPTION="${OPTION} --prior additive_gaussian". Refer to you paper, in the case of "SI-NR-GAN-I", do I need to add "--gn_train" to this option, i.e., OPTION="${OPTION} --gn_train --prior additive_gaussian", to train a "netGn" ? I am not sure here, maybe I missed some details. If there is no need to add anything here, could you please explain why. Your kind reply will help me understand your work well. Thanks a lot.

    how to calculate Intra-FID score?

    hi @takuhirok , Nice work!

      Can you tell me how to calculate the intra-fid score on the Cifar-10 dataset? How many clean images in the test dataset (or generated images by GAN) are used for calculating this score?
    

    Best, Youjiang Xu

    tabular data/ noisy instances

    Hi, thanks for sharing your implementation. I have two questions about it:

    1. Does it also work on tabular data?
    2. Is it possible to identify the noisy instances (return the noisy IDs or the clean set)?

    Thanks!
