Our methods include data preprocessing, improving the ALBERT model, output postprocessing, and ensembling. First, we use data augmentation to increase the size of the training set. Then, we implement several improvements on ALBERT, including incorporating a question answerability classification component, adding extra layers, and tuning the hyperparameters. Finally, after ensembling these models, we use named entity recognition to award the predicted answers with types of words corresponding to the question with a higher probability. Our proposed method reaches the EM/F1 scores of 79.949/82.584 on the test PCE-division leaderboard.

How then did some members of these communi- ties come together around a shared vision of China? Set against the backdrop of radical political movements in the late 1960s and 1970s, Yibing Du’s essay tackles this question. “Imagining the Chinese Homeland from America in the Radical Age, 1969-1976,” analyzes the Tiao-Yu Tia movement to uncover both the literal connections forged through activism and the shared imaginary developed around Communist China. A territorial agreement shifting sovereignty of the Tiao-Yu Tai islands from the United States to Japan catalyzed a social movement that caused both students and Chinatown activists to rethink their relationship to China and Taiwan. Drawing on stu- dent publications, mainstream news accounts, fiction, memoir, and oral hist...
