坤甸高中第三国立学校二年级学生使用“是…的”句式的 偏误分析 [PDF]

open access: yes, 2017
摘要:“是...的”句是动词谓语句的一种,突出强调与动作相关的某个成分,如用来强调动作发生的时间、处所、方式、条件、目的、对象、工具等;强调施事者;强调动作的受事者;和强调产生某种结果的动作行为,可见“是…的”句式非常重要。根据笔者了解,坤甸高中第三国立学校二年级的学生在学习汉语过程中对“是…的”句式的动词谓语句掌握不好,使用的时候常常出现一些错误。因此,笔者采用文献调查法和测验研究法对该校的学生使用“是…的”句式的偏误进行了调查并作了分析。 关键词:“是…的”句式 偏误分析 偏误原因 ...

基于迁移学习与卷积神经网络的鱼濒死预警系统研究 [PDF]

open access: yes, 2019
针对濒死鱼难以实时、高精度检测的问题,提出一种基于迁移学习与卷积神经网络的濒死鱼预警系统。通过迁移学习方法优化卷积神经网络的初始权重,使模型在训练初期即具有一定的泛化能力,优化前网络总体误差为1.75,优化后为0.75。为进一步提升模型性能,使用两组卷积神经网络作为特征提取器进行对比,结果显示,ZFnet网络(AP=0.902)略好于VGGnet网络(0.898),两者均显著优于常见的HOG+SVM算法(AP=0.259)。江苏省农业重大新品种创制项目(PZCZ201742 ...

基于四川地震预警站网数据的震相检测模型迁移学习研究

open access: yesDizhen xuebao
2023年中国建成了全球规模最大的地震预警网,预警网中的台站配置了速度计、加速度计、简易烈度计(MEMS)等多种地震仪器。目前用于深度学习模型训练的数据集主要由速度计数据组成,不同类型仪器记录的数据在处理时精度会下降。为了解决这一问题,本文使用Yu等(2023)发布的BRNN模型作为预训练模型;然后使用2万6 739条人工标注的四川地区的速度计、加速度计和MEMS数据进行迁移学习。实验结果表明:迁移学习显著提升了模型对加速度计和MEMS预警仪器数据记录到的Pg,Sg震相的检测精度 ...
