Aiming at the complex dynamic feature of large ship, an intelligent control structure based on library-similar knowledge-increasable neural network group is presented. This compounded control structure using the dynamic knowledge-increasable learning capability of the neural network groups, solve the problems of online identification and online design of the controller, so that the high precise output...
A new method of blind dereverberation of single channel is proposed to solve the existing problem about the study of speech signal. Firstly, segmentation of speech signal with variant length is proposed on the sampled speech signal to obtain relatively accurate estimation of the subsequent cepstrum, and the complex cepstrum is applied to the valid segments. Then, the pre-estimation of the room impulse...
Novel smoothing function method for support vector classification (SVC) and support vector regression (SVR) are proposed and attempt to overcome some drawbacks of former method which are complex, subtle, and sometimes difficult to implement. First, used Karush-Kuhn-Tucker complementary condition in optimization theory, unconstrained nondifferentiable optimization model is built. Then the smooth approximation...
A novel algorithm to face recognition based on video is presented in this paper. A framework is designed to work for face recognition from video sequence, which is robust to large-scale changes in facial pose and lighting conditions. Two approaches to improve the robustness of the algorithm are presented, a 2D-to-3D face model and self-PCA (principal component analysis) method based on bit-plane feature...
With respects to the windup problem exist in control system with Integral Saturation, a kind of fuzzy logic-based compensation method is proposed. Simulation is done to the designed fuzzy compensator and conventional compensator based on back calculation respectively. Simulation results show that the proposed fuzzy method gives generally better tracking performances than the back-calculation. The...
At first, some improvements were done in a single ant colony clustering algorithm, then, for different speed ant colony, clustering analysis was finished independently and in parallel by imitating the collaborative performance of multi-colony, and clustering results were combined into a hyper-graph and second division was made in the hyper-graph using ACA, at last, the test result for four databases...
As a density based clustering algorithm, DBSCAN plays an important role in data mining. Normally DBSCAN algorithm is computationally expensive, limiting its performance in large-scale data sets, especially in high dimensional data sets. The high complexity is rooted from the region queries, a very common operation in density based algorithms, which brings the complexity of the algorithms to O(n2),...
Thinning algorithm for fingerprint image based on directional images is studied deeply in this paper, and a high-efficiency improved algorithm come up. The method of labeled data is used in this paper. On the premise of ensuring the quality, the improved algorithm not only can accelerate the rate of thinning, but also extract the characteristic of the fingerprint.
Distance education is the most important part of modern education ideas, and the experiment manipulation tache is the key factor which restricts the more perfect of distance education mode. The paper analyses the application feasibility of virtual laboratory based on Web in distance education firstly, then makes a simply introduction of virtual laboratory, and describes the system structure and function...
Fuzzy Kohonen clustering network (FKCN) is a kind of self-organizing fuzzy neural network, it shows great superiority in processing the ambiguity and uncertainty of image. But FKCN will encounter some difficulties when used for real noisy color images and medical Sublingual vein color images segmentation. To overcome this defect, an improved FKCN algorithm is presented in this paper, which a new measurement...
The structure and size of steering trapezoid linkage can greatly affect the steering performance of automobile, therefore it is very important to adopt optimization methods to design the steering linkage. Being satisfied with the conditions of transmission capacity and boundary constraints, considering the ideal relationship of steering angles between external and internal wheels in steering linkage...
