On the Supermodularity of Active Graph-based Semi-supervised Learning with Stieltjes Matrix Regularization

2018 · arXiv (Cornell University)

Active graph-based semi-supervised learning (AG-SSL) aims to select a small set of labeled examples and utilize their graph-based relation to other unlabeled examples to aid in machine learning tasks. It is also closely related to …

Your fairness may vary: Group fairness of pretrained language models in toxic text classification.

2021 · arXiv (Cornell University)

We study the performance-fairness trade-off in more than a dozen fine-tuned LMs for toxic text classification. We empirically show that no blanket statement can be made with respect to the bias of large versus regular …
