基于GRNN与注意力机制模型的非侵入式家用负荷分解

为了提高识别精度,提出一种基于GRNN与注意力机制模型的非侵入式家用负荷分解方法.采用批标准化来减少神经网络层与层之间的耦合,利用GRNN强大的时间序列特征表示能力,来提取电力负荷入口处测得的总用电信息与各电器能耗之间的关系,同时利用注意力机制来减少模型的权重参数.最后通过算例验证了算法的可行性与优越性.     

A study on the factors that affect the adoption of Smart Water Grid

Due to recent climate changes that accompany drastic changes in water recycle process, extreme floods and droughts are occurring frequently throughout the world. In response to these events, Smart Water Management that refers to implement intelligent water information systems by IT convergence is considered as a new paradigm. In this study, we seek to explore the Smart Water Management, especially the adoption of Smart Water Grid Technology. We aim to review previous studies to identify factors that influence the adoption of the Smart Water Grid and to analyze the importance and priority of the factors affecting Smart Water Grid adoption, thereby presenting the successful adoption measures for Smart Water Grid in Korea. This study set a research model with the influencing factors in relation to the adoption of new IT technologies that were identified through the literature reviews of previous studies based on the TOE framework. This study also conducted empirical analysis of the findings and found out that the issue of privacy protection and security due to hacker’s attack would be emerged as a significant risk factor.

基于非凸l_p范数和G-范数的图像去模糊模型

图像去模糊一直是图像修复中的重要问题,针对经典的去模糊方法,提出一种耦合非凸lp(0≤p<1)范数和G范数的图像去模糊方法。该方法利用lp(0≤p<1)范数作为正则项约束,保证了图像的稀疏性要求;利用G范数作为保真项,保证在去模糊的同时有效抑制噪声并保持图像的细小特征,同时也给出新方法基于交替最小化的有效算法。实验结果表明新模型是可行的。
