The key security challenges and solutions on the cloud have been investigated in this paper with the help of literature reviews and an experimental model created on OPNET that is simulated to produce useful statistics to establish the approach that the cloud computing service providers should take to provide optimal security and compliance. The literatures(More)
A neural network (NN) pruning method optimized with particle swarm optimization (PSO) algorithm is proposed in this paper. Correlation merging algorithm is an important pruning method in NN structure design. Unlike general training method with back-propagation (BP), this paper uses PSO algorithm in the pruning process. The PSO is used to optimize the(More)
—As an essential way of human emotional behavior understanding, speech emotion recognition (SER) has attracted a great deal of attention in human-centered signal processing. Accuracy in SER heavily depends on finding good affect-related, discriminative features. In this paper, we propose to learn affect salient features for SER using convolutional neural(More)
Deep learning systems, such as Convolutional Neural Networks (CNNs), can infer a hierarchical representation of input data that facilitates categorization. In this paper, we propose to learn affect-salient features for Speech Emotion Recognition (SER) using semi-CNN. The training of semi-CNN has two stages. In the first stage, unlabeled samples are used to(More)
In order to improve the recognition accuracy of speech emotion recognition, in this paper, a novel hierarchical method based on improved Decision Directed Acyclic Graph SVM (improved DDAGSVM) is proposed for speech emotion recognition. The improved DDAGSVM is constructed according to the confusion degrees of emotion pairs. In addition, a geodesic(More)
In order to accurately get extent of the water deficit and therefore realize effective and water-saving irrigation, the application of wireless sensor networks (WSN) to precision irrigation system is explored based on the acoustic emission principle for crop water stress. Cluster based multi-hop routing algorithm is proposed to reduce energy consumption of(More)
