The aging issue has become an important issue of the world, mostly because the aging body makes elderly people in high risk. Since falling is a common accident when getting off bed and bed activities can help estimate sleeping quality, it is desirable to monitor bed activities for elderly people sleeping on beds. In addition, the deployment should be simple for the practicability. In this work, a...
Modern programming frameworks come with large libraries, with diverse applications such as for matching regular expressions, parsing XML files and sending email. Programmers often use search engines such as Google and Bing to learn about existing APIs. In this paper, we describe SWIM, a tool which suggests code snippets given API-related natural language queries such as "generate md5 hash code"...
With the popularity of cloud computing and SaaS, enterprises are willing to rent various cloud services and use them in their daily work. However, on-premise applications are still widely used inside enterprises. That is to say, to achieve the goal of business collaboration, a cloud service usually need to obtain business data from multiple sources, which include the relevant on-premise applications...
Multi-touch attribution, which allows distributing the credit to all related advertisements based on their corresponding contributions, has recently become an important research topic in digital advertising. Traditionally, rule-based attribution models have been used in practice. The drawback of such rule-based models lies in the fact that the rules are not derived form the data but only based on...
The application of Dynamic Data Driven Application Systems (DDDAS) to the command and control of swarms of Unmanned Aerial Vehicles (UAVs) is being investigated. Swarm intelligent systems are not only efficient at solving group-level problems, but also decentralized, controllable by few simple parameters, making possible the command and control of UAV swarms by a single operator. Four separate but...
Web services allow organizations to capture their human and software-based capabilities as modular software components that are called remotely over a network. In such service-oriented settings, it is important to establish an agreement that sets the obligations of the service provider and the expectations of the service consumer. Since traditional approaches such as Service Level Agreements (SLAs)...
Since learning Bayesian networks from data is difficult, a new approach is proposed. The particle swarm optimization (PSO) and minimum description length (MDL) are combined to obtain a suitable Bayesian network. MDL is the fitness function in this learning algorithm to evaluate the goodness of the network. By adopting MDL, the balance between simplicity and accuracy is assured, which enables the optimal...
Compared with traditional verification method for structural correctness of model based on Petri net graph reduction, The method in text adds reduction methods for the general iterative structure and the adjacent structure. A method for converting the non-freely chosen WF-net model into the freely chosen WF-net model in equivalence is put forward, therefore realizing the verification for all kinds...
