On the opportunities and risks of foundation models

…, C Ruiz, J Ryan, C Ré, D Sadigh, S Sagawa… - arXiv preprint arXiv …, 2021 - arxiv.org
AI is undergoing a paradigm shift with the rise of models (eg, BERT, DALL-E, GPT-3) that are
trained on broad data at scale and are adaptable to a wide range of downstream tasks. We …

Wilds: A benchmark of in-the-wild distribution shifts

PW Koh, S Sagawa, H Marklund… - International …, 2021 - proceedings.mlr.press
… We assess a model’s ability to normalize batch effects while preserving biological signal
by evaluating how well it can classify images of treated cells in the out-of-distribution test set. …

Just train twice: Improving group robustness without training group information

…, A Raghunathan, PW Koh, S Sagawa… - International …, 2021 - proceedings.mlr.press
Standard training via empirical risk minimization (ERM) can produce models that achieve low
error on average but high error on minority groups, especially in the presence of spurious …

Distributionally robust neural networks for group shifts: On the importance of regularization for worst-case generalization

S Sagawa, PW Koh, TB Hashimoto, P Liang - arXiv preprint arXiv …, 2019 - arxiv.org
… Classically, we can control the generalization gap with regularization techniques that
constrain the model family’s capacity to fit the training data. In the modern overparameterized …

Common interest, common good: Creating value through business and social sector partnerships

S Sagawa, E Segal - California management review, 2000 - journals.sagepub.com
Almost anywhere you look you can find evidence of stepped-up busi-ness-social sector
interaction. Alongside traditional giving-a local store collecting toys for the needy at Christmas, a …

Accuracy on the line: on the strong correlation between out-of-distribution and in-distribution generalization

…, R Taori, A Raghunathan, S Sagawa… - International …, 2021 - proceedings.mlr.press
For machine learning systems to be reliable, we must understand their performance in
unseen, out-of-distribution environments. In this paper, we empirically show that out-of-distribution …

An investigation of why overparameterization exacerbates spurious correlations

S Sagawa, A Raghunathan… - … on Machine Learning, 2020 - proceedings.mlr.press
We study why overparameterization—increasing model size well beyond the point of zero
training error—can hurt test error on minority groups despite improving average test error …

Openflamingo: An open-source framework for training large autoregressive vision-language models

…, S Gadre, S Sagawa, J Jitsev, S Kornblith… - arXiv preprint arXiv …, 2023 - arxiv.org
… This limits the academic community’s ability to conduct research on autoregressive vision-language …
For ease of comparison to Flamingo, we calculate each OpenFlamingo model’s

Orientation of erythrocytes in a strong static magnetic field

…, T Takeuchi, N Kawaguchi, S Sagawa, S Onishi… - 1993 - ashpublications.org
… This phenomenon is ascribable to paramagnetic anisotropy retained by the heme of hemoglobin
S that is polymerized in fiber by deoxygenation. This paper deals with the Orientation of …

Extending the wilds benchmark for unsupervised adaptation

S Sagawa, PW Koh, T Lee, I Gao, SM Xie… - arXiv preprint arXiv …, 2021 - arxiv.org
… Self-training methods “pseudo-label” unlabeled examples with the model’s own predictions
and then train on them as if they were labeled examples. These methods often also use …
