Exploiting Biased Models to De-bias Text: A Gender-Fair Rewriting Model

ACL 2023long

Natural language generation models reproduce and often amplify the biases present in their training data. Previous research explored using sequence-to-sequence rewriting models to transform biased model outputs (or original texts) into more gender-fair language by creating pseudo training data throu…

How Suitable Are Subword Segmentation Strategies for Translating Non-Concatenative Morphology?

EMNLP 2021finding

Data-driven subword segmentation has become the default strategy for open-vocabulary machine translation and other NLP tasks, but may not be sufficiently generic for optimal learning of non-concatenative morphology. We design a test suite to evaluate segmentation strategies on different types of mor…

On Biasing Transformer Attention Towards Monotonicity

NAACL 2021long

Many sequence-to-sequence tasks in natural language processing are roughly monotonic in the alignment between source and target sequence, and previous work has facilitated or enforced learning of monotonic attention behavior via specialized attention functions or pretraining. In this work, we introd…
