Bagging adversarial training for question answer ranking

Abstract

A computer-implemented method is provided to preforming bagging adversarial training for question-answer ranking models using neural networks. The method includes generating first question and answer (QA) pairs for a given question as a first training dataset to train a QA ranking model to build a pre-trained QA ranking model. A generative adversarial network (GAN) includes a generator and a discriminator configured to produce adversarial inputs to provide an updated training dataset. The pre-trained QA ranking model is retrained with the updated training dataset with the bagging adversarial training process. A plurality of trained models is sampled to generate a bagged model ensemble as a final trained QA ranking model for QA ranking tasks.
