面向边缘计算应用的宽度孪生网络

Broad Siamese Network for Edge Computing Applications

边缘计算是将计算、存储、通信等任务分配到网络边缘的计算模式.它强调在用户终端附近执行数据处理过程,以达到降低延迟,减少能耗,保护用户隐私等目的.然而网络边缘的计算、存储、能源资源有限,这给边缘计算应用的推广带来了新的挑战.随着边缘智能的兴起,人们更希望将边缘计算应用与人工智能技术结合起来,为我们的生活带来更多的便利.许多人工智能方法,如传统的深度学习方法,需要消耗大量的计算、存储资源,并且伴随着巨大的时间开销.这不利于强调低延迟的边缘计算应用的推广.为了解决这个问题,我们提出将宽度学习系统(Broad learning system,BLS)等浅层网络方法应用到边缘计算应用领域,并且设计了一种宽度孪生网络算法.我们将宽度学习系统与孪生网络结合起来用于解决分类问题.实验结果表明我们的方法能够在取得与传统深度学习方法相似精度的情况下降低时间和资源开销,从而更好地提高边缘计算应用的性能.

Edge computing is a paradigm that allocates computing,storage,communication tasks to the edge of network.It emphasizes that data processing should be placed in the proximity of user terminals in order to reduce latency and energy consumption while protecting user privacy.However,resources for computation,storage and power at the edge of network are limited,which brings new challenges to edge computing applications.With the emergence of edge intelligence,people prefer to combine edge computing applications with artificial intelligence techniques to bring more convenience to our lives.Many artificial intelligence methods such as traditional deep learning methods,need to consume a lot of computation and storage resources with a huge time consumption.It is not conducive to the popularity of edge computing applications,which always require low latency.In order to resolve such a problem,we propose that shallow network methods such as broad learning system can be applied in edge computing applications and design a broad Siamese network algorithm.We combine broad learning system(BLS)with Siamese network for classification tasks.Experimental results show that our method can reduce the cost of time and resources,while achieving a similar result as deep learning methods,consequently improving the performance of edge computing applications.
