Parameter-Efficient Finetuning of Transformers for Source Code
CoRR, 2022 Pretrained Transformers achieve state-of-the-art performance in various code-processing tasks but may be too large to be deployed. As software development tools often incorporate modules for various purposes which may potentially use a single instance of the pretrained model, it appears relevant to utilize parameter-efficient fine-tuning for the ...

Dizhen xuebao, 2020 基于首都圈数字地震台网的宽频带资料，首先采用CAP方法确定了永清MS4.3地震和廊坊MS3.0地震的震源机制解：永清地震节面Ⅰ的走向、倾角和滑动角分别为52°，62°和−140°，节面Ⅱ的走向、倾角和滑动角分别为300°，55°和−35°；廊坊地震节面I的走向、倾角和滑动角分别为48°，57°和−147°，节面Ⅱ的走向、倾角和滑动角分别为299°，63°和−38°。两次地震的震源机制解较为一致，推测它们可能具有相同的发震断层。利用近震转换波获得两次地震的震源深度，分别为19 km和13 km ...

Dizhen xuebao, 2021 在进行未来破坏性地震的强地面运动数值模拟时，震源参数选取的准确性对地震动预测的结果影响很大。震源参数的确定存在很多不确定性因素，既包含随机的不确定性因素，又包含认知的不确定性因素。本文在大量地震事件及文献调研的基础上，运用统计学方法对具备随机不确定性特征的震源参数进行统计研究，以震源参数经验公式的形态建立解释其随机性和不确定性的数学模型。为了研究局部地区震源参数的定标关系特征，获得更加适用于局部地震密集区域，尤其是包含中国大陆地区在内的局部区域的震源参数的经验关系，本文从GCMT地震目录中选取了1 ...
