    Hybrid lead halide perovskites for ultrasensitive photoactive switching in terahertz metamaterial devices by Manjappa, Manukumara, Srivastava, Yogesh Kumar, Solanki, Ankur, Kumar, Abhishek, Sum, Tze Chien, Singh, Ranjan

    Published 2020
    “…However, optoelectronic application of halide perovskites in realizing highly efficient subwavelength photonic devices has remained a challenge. Here, the remarkable photoconductivity of organic-inorganic lead halide perovskites is exploited to demonstrate a hybrid perovskite-metamaterial device that shows extremely low power photoswitching of the metamaterial resonances in the terahertz part of the electromagnetic spectrum. …”

    Active learning for ontological event extraction incorporating named entity recognition and unknown word handling by Han, Xu, Kim, Jung-jae, Kwoh, Chee Keong

    Published 2016
    “…Moreover, the confidence scores of events produced by event extraction systems are not reliable for ranking documents in terms of informativity for supervised learning. We here propose a novel committee-based active learning method that supports multi-event extraction tasks and employs a new statistical method for informativity estimation instead of using the confidence scores from event extraction systems. …”
