卷积神经网络迁移学习在局部放电类型诊断中的应用

open access: yesGaoya dianqi, 2022
气体绝缘金属封闭开关设备的局部放电具有随机性,即使同一类型缺陷仍有较多表观变化形式,传统模式识别构造的特征难以适应其多变性;近年来兴起的卷积神经网络虽具有自适应提取特征的能力,但训练得到性能更好的网络模型一方面需要增加网络深度,另一方面需要更多的数据样本作为支撑。鉴于此,提出了基于在ImageNet数据集上训练的VGG、InceptionV3、Resnet50 3种网络模型迁移学习的GIS局部放电模式识别方法,并将网络提取的特征应用于在小数据集下表现良好的经典分类器SVM ...

Content Moderation and Community Standards: The Disconnect Between Policy and User Experiences Reporting Harmful and Offensive Content on Social Media

open access: yesPolicy &Internet, Volume 17, Issue 3, September 2025.
ABSTRACT Moderating harmful and offensive content on social media is challenging for digital platforms that seek to balance regulation and censorship across a diverse user group. It is further complicated by discrepancies between platform policies, user expectations and user experiences.

Child Rights Impact Assessment: A Policy Tool for a Rights‐Respecting Digital Environment

open access: yesPolicy &Internet, Volume 17, Issue 3, September 2025.
ABSTRACT Businesses that develop digital products and services often anticipate generic users, paying insufficient attention to the needs and rights of children who may use or be impacted by their practices. This article investigates the potential of child rights impact assessment (CRIA) as a policy tool to protect and respect children's rights in the ...

More Complex Constrained Language? An Investigation on Nominal Complexity in Constrained Spoken English Varieties of ESL, EFL, and Interpreted English

open access: yesInternational Journal of Applied Linguistics, Volume 35, Issue 3, Page 1482-1494, August 2025.
ABSTRACT While previous research has established nominal complexity as a key indicator of grammatical complexity, its multi‐dimensional manifestation in constrained varieties remains underexplored. This study investigates the distribution of complex nominal structures in constrained spoken English varieties, specifically English as a Second Language ...

基于深度学习的髋关节应力分布算法研究

open access: yes智能科学与技术学报, 2019
针对髋关节软骨的应力分布算法研究问题,设计了一个基于深度学习模型来代替有限元分析。该深度学习模型分为无监督学习模块和有监督学习模块,首先使用无监督学习模块对髋关节的软骨和股骨进行形状编码;之后实现对应力分布数据的编码与解码,使得应力数据能够与神经网络相结合;然后通过监督学习,利用编码好的应力数据进行监督,使神经网络学习得到一个从髋关节软骨和股骨的形状码到应力分布的应力码的映射关系;最终得到一个拟合的深度学习模型。此模型能够在一定程度上模拟有限元分析方法,但是由于其平均绝对误差和归一化平均绝对误差比较大 ...
