This paper proposes a probabilistic Latent Emotion Analysis (pLEA) model, which is an extension of probabilistic Latent Semantic Analysis (pLSA) model, to discover latent emotion topics considering theoretical and empirical concepts from psychology and art theory. The traditional pLSA models performed poorly since the statistical model are hardly narrowing the semantic gap between low-level image...
The dynamical phenomenon of cyclic variability in combustion governed by autoignition in homogeneous charge compression ignition engines with large amounts of residual gases is investigated. A novel model is derived with two states that capture the coupling between engine cycles due to the thermal energy in the recycled residual gases and the recycled chemical energy in the unburned fuel. With the...
In order to explore the role of the market confidence and reputation feedback systems in online transactions, a computational experiment model based on the multi-agent is used in this paper. By introducing experience weighted attraction learning algorithm which endows the agent with the bounded rationality, the model can represent the revolution trends in online market and analyze the effect of the...
Constructing Web service workflow faces huge challenges in the volatile, heterogeneous, distributed environment: it is necessary to consider the dynamic changes in web services, but also take into account the rapid method of modeling workflow. Comparing workflow modeling and artificial intelligence planning process, if the Web service as a planned action (or activity), then the modern AI planning...
In order to carries on the plan and the control to aircraft level flight, the attitude and the route has been analyzed. First obtain that the factors control the level attitude are the roll angle and the yaw angle, and infers the computation algorithm of attitude; then obtain that the factors control the level route are the route position and the radius of turn, and infers the algorithm of flight...
Web service is a distributed computing model which has characteristics of loose coupling, self-description and strong self-government, how to evaluate the degree of Web service security is a challenging problem. On the basis of analyzing the threat which Web service facing, a security evaluation method based on STRIDE model for Web service is proposed. According to its own features of Web service...
The ability to have an insight into customer "values and action" is the foundation for enhancing managerial decision-making effectiveness and customer relationship. From the perspective of customer value, this paper proposes the customer "value-action" insight analysis model based on data mining technology. The assessment of customer value, subdivision and cluster of the customers,...
This paper develops and demonstrates a taxi pre-alarm system which is based on transportation hub information platform and urban taxi information platform and running in transportation hub in order to maintain continuous, enough and rational taxi supply and aiming at improving the taxi service lever of transportation hubs. The system is mainly made up of three key models: real-time taxi-demand estimate...
