In this paper, we study a new problem of continuous learning from doubly-streaming data where both data volume and feature space increase over time. We refer to the doubly-streaming data as trapezoidal data streams and the corresponding learning problem as online learning from trapezoidal data streams. The problem is challenging because both data volume and data dimension increase over time, and existing...
Precision agriculture is a data-driven farming practice that uses intra-and inter-field information to optimize farming operations. The "brain" of precision agriculture is a decision support system (DSS) that acquires data from various sources, analyzes them, and recommends actions to farmers. Recently cloud computing has been used to improve the scalability and reliability of a DSS. Cloud-based...
Simple Linear Iterative Clustering (SLIC) algorithm is one of the best methods to generate superpixels in terms of segmentation effect and running speed. In an effort to solve the problem of inaccurate segmentation in traditional SLIC method, an improved SLIC algorithm is put forward in this paper. This algorithm adopts a nonlinear filter to preprocess the image, which can remove noise and smooth...
No-reference objective stereo video quality assessment plays an important role in stereo video content production, especially to the sense of 2D-to-3D video conversion. The main problem needed to consider when designing an objective quality assessment model is to make the assessment result close to human perception. In this paper, a no-reference objective stereo video quality assessment method is...
Motion retargeting technology has been widely used in the production of animated cartoon and human-computer interaction. In this paper, a Space-Time constraints-based motion retargeting framework is proposed. For the given captured motion data, we firstly initialized the root position based on the difference between original and target character, then we fixed the degree of freedom of the corresponding...
As a main defect, the crack has enormous threat on structure safety, which the great majority is mix-mode in engineering. At present, mix-mode crack analysis mainly depend on the manpower way to rebuilt continuously crack structure one by one to simulate the process of crack growth. And the process of modeling crack structure also is complex. To improve the analysis efficiency and provide fast decision...
Based on a kind of typical high speed monohull vessel, the paper discusses an integrate optimization's method of Synthetical Fundamental Mechanics Characteristic with the materials of some ships and some relevant experience expressions. The authors use the weighted sum of rapidity, sea-keeping ability and maneuverability as the sub-objective function of ship performances; use the weighted sum of static...
In this paper, VC++ serves as a workspace to establish the features of speediness and navigation speed controlling. A mathematical model of intelligent propulsion system of an adjustable-pitch-screw-propelled hydrofoil sliding craft was built up, and then applied the fuzzy-genetic algorithm (FGA), to program the optimizing-computing process of the best combination of the controlling parameters of...
Agent-based grid data loading method aims at integrating heterogeneous hospitalspsila information systems into a medical information exchange platform based on grid middleware. It collects distributed data sets for decision support system, which makes data sources expanded from independent database modes to medical information systems in wide area. Virtual data access with grid service improves data...
