Blancing Principle for Domain Adaptation

NeurIPS 2021 Paper

Abstract

We address the unsolved algorithm design problem of choosing a justified regularization parameter in unsupervised domain adaptation. This problem is intriguing as no labels are available in the target domain. Our approach starts with the observation that the widely-used approach of minimizing the source error, weighted by a distance measure between source and target feature representations, shares characteristics with regularized ill-posed inverse problems. Regularization parameters in inverse problems can be chosen by the fundamental principle of balancing approximation and sampling errors. We use this principle to balance learning errors and domain distance in a target error bound. As a result, we obtain a theoretically justified rule for the choice of the regularization parameter. In contrast to the state of the art, our approach allows source and target distributions with disjoint supports. An empirical comparative study on benchmark datasets underpins the performance of our approach.

Compute Results

Train domain adaptation method with balancing principle by calling the bp configs:

CUDA_VISIBLE_DEVICES=<device-id> PYTHONPATH=. python scripts/train.py --config configs/<your-bp-config>.json

# running a CMD experiment with BP
CUDA_VISIBLE_DEVICES=0 PYTHONPATH=. python scripts/train.py --config configs/config.minidomainnet_bp_cmd.json.json
# running a MMD experiment with BP
CUDA_VISIBLE_DEVICES=0 PYTHONPATH=. python scripts/train.py --config configs/config.minidomainnet_bp_mmd.json.json

Evaluate results Set the respective base_dir and method setting in the viz/results_extractor_MiniDomainNet.py file and run:

PYTHONPATH=. python viz/results_extractor_MiniDomainNet.py

CVE-2007-4559 Patch

Patching CVE-2007-4559

Hi, we are security researchers from the Advanced Research Center at Trellix. We have began a campaign to patch a widespread bug named CVE-2007-4559. CVE-2007-4559 is a 15 year old bug in the Python tarfile package. By using extract() or extractall() on a tarfile object without sanitizing input, a maliciously crafted .tar file could perform a directory path traversal attack. We found at least one unsantized extractall() in your codebase and are providing a patch for you via pull request. The patch essentially checks to see if all tarfile members will be extracted safely and throws an exception otherwise. We encourage you to use this patch or your own solution to secure against CVE-2007-4559. Further technical information about the vulnerability can be found in this blog.

If you have further questions you may contact us through this projects lead researcher Kasimir Schulz.
