    QG-Net: A Data-Driven Question Generation Model for Educational Content
    (2020-04-23) Wang, Jack; Baraniuk, Richard
    The ever growing amount of educational content renders it increasingly difficult to manually generate sufficient practice or quiz questions to accompany it. This thesis introduces QG-Net, a recurrent neural network-based model specifically designed for automatically generating quiz questions from educational content such as textbooks. QG-Net, when trained on a publicly available, general-purpose question/answer dataset and without further fine-tuning, is capable of generating high quality questions from textbooks, where the content is significantly different from the training data. Indeed, QG-Net outperforms state-of-the-art neural network-based and rules-based systems for question generation, both when evaluated using standard benchmark datasets and when using human evaluators. QG-Net also scales favorably to applications with large amounts of educational content, since its performance improves with the amount of training data.

    Selective Transparent Headphone
    (Rice University, 2014-12-18) Wang, Jack; Yao, Tianyi; Xia, Stephen
    Describes the theory and process of creating a selective transparent headphone, which filters in important sound signals from the environment to the user while suppressing all other signals. The article focuses on a small step of the process: isolating human speech.
