Convolutional Matrix Factorization for Document Context-Aware Recommendation
A novel context-aware recommendation model that integrates convolutional neural network (CNN) into probabilistic matrix factorization (PMF) that captures contextual information of documents and further enhances the rating prediction accuracy is proposed. Expand
Group-Based Trust Management Scheme for Clustered Wireless Sensor Networks
A new lightweight group-based trust management scheme (GTMS) for wireless sensor networks, which employs clustering and reduces the cost of trust evaluation and is more suitable for large-scale sensor networks. Expand
A Triaxial Accelerometer-Based Physical-Activity Recognition via Augmented-Signal Features and a Hierarchical Recognizer
An accelerometer sensor-based approach for human-activity recognition using a hierarchical scheme that recognizes three states and 15 activities with an average accuracy of 97.9% using only a single triaxial accelerometer attached to the subject's chest. Expand

CODE is a coordination-based data dissemination protocol for wireless sensor networks that considers energy efficiency and network lifetime, especially for sensor networks with high node density, and is based on a grid structure. Expand
Trust Management Problem in Distributed Wireless Sensor Networks
A novel lightweight group based trust management scheme (GTMS) for distributed wireless sensor networks in which the whole group will get a single trust value, which helps in keeping minimum resource utilization at the sensor nodes. Expand
Particle swarm optimization based clustering algorithm with mobile sink for WSNs
Extensive simulation results show that the energy consumption is much reduced, the network lifetime is prolonged, and the transmission delay is reduced in the proposed routing algorithm than some other popular routing algorithms. Expand
TTM: An Efficient Mechanism to Detect Wormhole Attacks in Wireless Ad-hoc Networks
A transmission time based mechanism (TTM) to detect wormhole attacks - one of the most popular & serious attacks in Wireless Ad Hoc Networks. Expand
Improved trust-aware recommender system using small-worldness of trust networks
Based on five trust networks obtained from the real online sites, it is verified that the trust network is the small-world network: the nodes are highly clustered, while the distance between two randomly selected nodes is short. Expand
