论文摘要

深度神经网络(DNN)已成功地用于执行分类和回归任务,尤其是在基于计算机视觉的应用程序中。最近,由于物联网(IoT)的广泛部署(IoT),我们确定时间序列数据的分类任务,特别是来自不同传感器的分类任务至关重要。在本文中,我们介绍了SRDCNN:基于强烈的深度卷积神经网络(DCNN)深度体系结构,以执行时间序列分类任务。拟议方法的新颖性是网络权重由L1和L2 Norm惩罚正规化。两种正则化方法都共同解决了较少的培训实例,更快的训练过程的要求,通过纳入重量向量的稀疏以及控制权重值来避免过度拟合问题的实际问题。我们将提出的方法(SRDCNN)与相关的最新算法进行比较,包括使用公开可用的时间序列分类基准(UCR/UEA档案)时间序列数据集,并证明所提出的方法提供了出色的性能。我们认为SRDCNN通过深刻控制网络参数来解决现实生活时间序列传感器信号的培训实例不足问题,因此可以更好地对深度体系结构进行概括。

Deep Neural Networks (DNN) have been successfully used to perform classification and regression tasks, particularly in computer vision based applications. Recently, owing to the widespread deployment of Internet of Things (IoT), we identify that the classification tasks for time series data, specifically from different sensors are of utmost importance. In this paper, we present SRDCNN: Strongly Regularized Deep Convolution Neural Network (DCNN) based deep architecture to perform time series classification tasks. The novelty of the proposed approach is that the network weights are regularized by both L1 and L2 norm penalties. Both of the regularization approaches jointly address the practical issues of smaller number of training instances, requirement of quicker training process, avoiding overfitting problem by incorporating sparsification of weight vectors as well as through controlling of weight values. We compare the proposed method (SRDCNN) with relevant state-of-the-art algorithms including different DNNs using publicly available time series classification benchmark (the UCR/UEA archive) time series datasets and demonstrate that the proposed method provides superior performance. We feel that SRDCNN warrants better generalization capability to the deep architecture by profoundly controlling the network parameters to combat the training instance insufficiency problem of real-life time series sensor signals.
