Older augmentation tricks, such as synonym swaps or unconditioned language-model word replacement, often produce sentences whose meaning no longer fits the original class. The authors propose one recipe that works with any pre-trained transformer: 2. **[On the Intrinsic and Extrinsic Fairness Evaluation Metrics for Contextualized Language Representations](https://md.research.elamur.ai/free/en/papers/cao-2022-intrinsic-extrinsic-fairness-evaluation-metrics/)** *(2022 · 100 citations)* Fairness in NLP is measured in two ways. Intrinsic metrics probe a pre-trained language model directly. Extrinsic metrics look at group disparities in the outputs of a downstream system. People often assume a model that looks fair intrinsically will also behave fairly downstream, but this had not been checked broadly… ## All works 4 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1.
