CREST: A Joint Framework for Rationalization and Counterfactual Text Generation

ACL 2023long

Selective rationales and counterfactual examples have emerged as two effective, complementary classes of interpretability methods for analyzing and training NLP models. However, prior work has not explored how these methods can be integrated to combine their complementary advantages. We overcome thi…

The Inside Story: Towards Better Understanding of Machine Translation Neural Evaluation Metrics

ACL 2023short

Neural metrics for machine translation evaluation, such as COMET, exhibit significant improvements in their correlation with human judgments, as compared to traditional metrics based on lexical overlap, such as BLEU. Yet, neural metrics are, to a great extent, “black boxes” returning a single senten…

Sparse and Continuous Attention Mechanisms

NeurIPS 2020spotlight

Exponential families are widely used in machine learning; they include many distributions in continuous and discrete domains (e.g., Gaussian, Dirichlet, Poisson, and categorical distributions via the softmax transformation). Distributions in each of these families have fixed support. In contrast, fo…
