Notice: This website is continuously updated as new conference proceedings and journal volumes are published. Consequently, the figures presented here may differ from those reported in our publications.


A brief overview of our methodology is provided on the Methods page, along with references to publications documenting our approach and links to the code and data used in each study.


The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates.

Reproducibility Variable Result LLM Response
Research Type Experimental We evaluate COT and COTT on a variety of standard benchmarks that induce various types of distribution shift synthetic, novel subpopulation, and natural and show that our approaches significantly outperform existing state-of-the-art methods with up to 3x lower prediction errors.

Pseudocode No The paper does not contain any clearly labeled pseudocode or algorithm blocks.
Open Source Code Yes Our code can be found at https://github.com/luyuzhe111/COT.
Open Datasets Yes We evaluate COT and COTT on a variety of standard benchmarks that induce various types of distribution shift synthetic, novel subpopulation, and natural and show that our approaches significantly outperform existing state-of-the-art methods with up to 3x lower prediction errors. (followed by list of datasets like CIFAR10, CIFAR100, Image Net, BREEDS, and WILDS benchmarks which are standard publicly available datasets)
Dataset Splits Yes For datasets without an official validation set, we randomly sampled a subset of the official training set as the validation set to perform calibration and learn thresholds for ATC and COTT. We reserved 10000 images from the training set as the validation set.
Hardware Specification Yes We performed training in Py Torch [31], and we used RTX 6000 Ada GPUs.
Software Dependencies No The paper mentions PyTorch but does not specify a version number for it or any other software libraries used.
Experiment Setup Yes We trained Res Net18 from scratch, using SGD with momentum equal to 0.9 for 300 epochs. We set weight decay to 5 10 4 and batch size to 200. We set the initial learning rate to 0.1 and multiply it by 0.1 every 100 epochs.
