Pytorch implementation for "Open Compound Domain Adaptation" (CVPR 2020 ORAL)

Last update: Dec 15, 2022

Overview

Open Compound Domain Adaptation

Overview

Open Compound Domain Adaptation (OCDA) is the author's re-implementation of the compound domain adaptator described in:
"Open Compound Domain Adaptation"
Ziwei Liu^*, Zhongqi Miao^*, Xingang Pan, Xiaohang Zhan, Dahua Lin, Stella X. Yu, Boqing Gong (CUHK & Berkeley & Google) in IEEE Conference on Computer Vision and Pattern Recognition (CVPR) 2020, Oral Presentation

Further information please contact Zhongqi Miao and Ziwei Liu.

Requirements

PyTorch (version >= 0.4.1)
scikit-learn

Updates:

11/09/2020: We have uploaded C-Faces dataset. Corresponding codes will be updated shortly. Please be patient. Thank you very much!
06/16/2020: We have released C-Digits dataset and corresponding weights.

Data Preparation

[OCDA Datasets]

First, please download C-Digits, save it to a directory, and change the dataset root in the config file accordingly. The file contains MNIST, MNIST-M, SVHN, SVHN-bal, and SynNum.

For C-Faces, please download Multi-PIE first. Since it is a proprietary dataset, we can only privide the data list we used during training here. We will update the dataset function accordingly.

Getting Started (Training & Testing)

C-Digits

To run experiments for both training and evaluation on the C-Digits datasets (SVHN -> Multi):

python main.py --config ./config svhn_bal_to_multi.yaml

After training is completed, the same command will automatically evaluate the trained models.

C-Faces

We will be releasing code for C-Faces experiements very soon.

C-Driving

Please refer to: https://github.com/XingangPan/OCDA-Driving-Example .

Comments

Questions regarding the decoder

Thanks for releasing the code. It seems that the paper forgets to mention how to train the decoder while in the code the decoder is updated jointly with the domain encoder.

Memory module for Semantic Segmentation

Hi, from my understanding the memory module is a matrix which holds for each row the mean latent vector for each class (or - its centroid) over the source data. Later these centroids are also used to order the target data for a curriculum learning step.

What I don't understand is how the memory module is implemented for semantic segmentation. when there is a single class for each image the division to centroids is clear but what is your method when the labels are segmentation maps?

I did not find an explanation for this in the paper, or the code.

Thanks, Nadav

Motivation behined Concept and Domain Factor Selector Linear Networks
As I understand from the code, instead if using the Domain Factor network for weighting the memory value as explained in the paper, you train a "Concept Selector" and a "Domain Factor Selector" linear networks to output weights for both the memory and the domain factor net output to get the final v_transfer value when combing with the direct encoder output.

Can you please explain the motivation behind this change?

Can you explain the motivation behind training Man network before the domain factor network and not training both concept and domain factor selectors at once? (and in short, why not remove step 2)

Can you explain how these changes are applied in the semantic segmentation task training?

Thanks.

There is no semantic segmentation label in C-Driving's train dataset.

Thanks for the interesting paper.

However, there is no semantic segmentation label for C-Driving's training dataset.

I can't even find it in the BDD100K dataset.

C-Driving has only images, but can I know where to get the semantic segmentation map..?

C-Faces experiments

Hi,

I would like to reproduce the results of C-Faces dataset but I noticed that you shared only the code to reproduce the experiments on Digits. Can you also share the code for C-Faces?

Thank you!

C-Driving segmentation code

Hi, I am trying to reproduce the results from your paper using your code. I have noticed that the code which you have shared is for classification of digits. Can you also share the architecture and code for C-Driving segmentation as well. Thank you

Missing dataset "C-Faces" in https://liuziwei7.github.io/projects/CompoundDomain.html

Hi, I have recently started working on Domain Adaption. I am trying to reproduce the results from your code. I followed the gdrive link from github site and found that the C-Faces was missing, Can you please add this dataset. Thank you
