Reducing cohort bias in natural language understanding systems with targeted self-training scheme

ACL 2023industry

Bias in machine learning models can be an issue when the models are trained on particular types of data that do not generalize well, causing under performance in certain groups of users. In this work, we focus on reducing the bias related to new customers in a digital voice assistant system. It is o…

Semi-supervised Adversarial Text Generation based on Seq2Seq models

EMNLP 2022industry

To improve deep learning models’ robustness, adversarial training has been frequently used in computer vision with satisfying results. However, adversarial perturbation on text have turned out to be more challenging due to the discrete nature of text. The generated adversarial text might not sound n…

Unsupervised training data re-weighting for natural language understanding with local distribution approximation

EMNLP 2022industry

One of the major challenges of training Natural Language Understanding (NLU) production models lies in the discrepancy between the distributions of the offline training data and of the online live data, due to, e.g., biased sampling scheme, cyclic seasonality shifts, annotated training data coming f…
