    Abstract
    This dissertation describes work I have conducted over five academic years 2013/14 through 2017/18 as a NASA Space Technology Research Fellow at the University of Hawai'i Institute for Astronomy. The focus has been the characterization and improvement of the Selex Avalanche Photodiode HgCdTe InfraRed Array (SAPHIRA), a 320 x 256@24um pitch metal organic vapor phase epitaxy mercury cadmium telluride array that provides new capabilities and performance for near infrared (NIR) astronomy. This has involved more than a dozen arrays, working closely with the manufacturer so as to provide feedback for improvement of the next generation.

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
