Visual-based 3D model retrieval presents great potential, for its broad application prospects and relatively high accuracy. A branch of visual-based methods utilizes scale invariant feature transform (SIFT) on 2D rendered images of a 3D model viewed from regularly sampled locations on a sphere, and then the bag-of-words framework is employed to improve the retrieval precision. However, in existing...
Music labels, especially those related to high level semantics are very useful in music retrieval and recommendation, but normally hard to acquire. In the submission to ISMIR'07, Mohamed Sordo proposed a novel model, i.e., propagation of labels, to annotate music with existing labels, by using the content-based music similarity distance. In that model, a partially annotated collection with a lot of...
The explosion in social networking sites allows people interact with friends on web more frequently and easily. Thus, applications on social networking such like the social networking advertising have been regarded as a wonderful opportunity for marketing. In this study, we try to simulate the content sharing behavior in social networking sites and we optimize simulation parameters by using evolution...
This paper establishes the nonlinear relationship predication model of artificial neural network (ANN) between the drinking water chemistry indicators and the morbidity of Kaschin-Beck disease in Sichuan districts by BP (Back-Propagation) arithmetic. Firstly, the input for the network are determined by the result of correlation analyses which analyses the water chemistry indicators and the morbidity...
Network traffic has the characteristic of self similarity. We can create its model based on measure and physical method. The detail model includes FBM, FGN, on/off, and so on. Then carried on research and practice on the concrete problem that the flow of network produced, such as: distributed production of random number, control algorithms on the basis of feedback mechanism of the flow. Especially...
The use of 3D computer-aided design (CAD) models to support construction project planning has been increasing in the previous year. 3D CAD models reveal more planning ideas by visually showing the construction site environment in different stages of the construction process. Using 3D CAD models together with scheduling software to prepare construction plan can identify errors in process sequence and...
