One of eChina - UK projects in collaboration between universities from both sides is designed to develop virtual learning community ( VLC) among in-service teachers and explore from pedagogic perspective how to conduct VLC. In accordance with reflective learning and collaborative learning, three online learning modules have been jointly created by Chinese and UK educational specialists, and one unit from each module has been piloted by a group of senior teachers. Through analyzing the processes of course design and pilot, supported by quantitative and qualitative research into the experiences of pilot participants, the paper identifies some core factors influencing the quality of VLC and suggests that more attention should be given to the interactive learning process within VLC rather than to create well-structured learning materials before hand. It has also analyzed VLC as a promising approach to support professional development of in-service teachers from the perspective of continuous improvement process. There is much to be researched into the approach of VLC.展开更多

文摘人体行为识别(Human Activity Recognition,HAR)是当前众多研究工作的基石,对于推动人机交互和智能数字化转型具有巨大潜力。由于目标域样本较难采集,现有方法在跨域识别方面表现不佳。为解决这一问题,提出一种新的WiFi使能跨域HAR方法,从WiFi信号中获取信道状态信息(Channel State Information,CSI)并转化为图像,在基于Wasserstein距离和梯度的生成对抗网络(Wasserstein Generative Adversarial Network with Gradient Penalty,WGAN-GP)中引入双判别器,通过与源域样本和单目标域样本特征联合对抗,生成同时带有双域特征的虚拟样本。该方法还结合基于Mean Teacher的半监督学习设计识别分类(Recognition and Classification,RC)模块,通过对有标记样本与无标记样本分别构造损失函数,进行整体一致性损失的评估,实现对目标域样本的识别。实验结果证明了所提方法能够在减轻目标域样本采集压力的同时,实现较高的检测精度,在手势与动作的数据集上测试准确率分别达到92.71%和86.65%。
