Interactive control strategies have been widely used in many rehabilitation robotic devices. The distinctive feature of these strategies is that the patient can be encouraged to actively participant in the therapy program. In this paper, a novel adaptive impedance control method, which allows the patient to actively influence the robot movement trajectory, is presented. The control algorithm developed...
The bag-of-features based models are widely used for image classification. In these models, an image is represented as a set of visual words which come from a dictionary. Therefore, a well learned dictionary is responsible for the discriminative power of representations of images. Our observations show that the representation of an image carries rich underlying information of a dictionary, so we propose...
A case-based pattern design method is proposed to translate an image into a pattern of certain style. The method has two phases. Pattern style and knowledge are learned in case-learning phase, case mapping database and rule database are results of this phase and will serve as memory unit and logical unit respectively. In design phase, user designates the objects in an input image, visual features...
The effect of the shock environment induced by clamp band satellite-rocket separation is usually analyzed by the shock response spectrum (SRS). This paper presents a method of predicting SRS data in a new shock environment on the basis of great accumulated shock tests. Firstly, the shock response spectrums that correspond to the time domain signals of the existing shock tests are calculated by means...
Extreme Learning Machine has the quality of fast learning speed, good generalization performance, and high diagnostic accuracy. For analog circuit fault diagnosis and health management (PHM) applications, this paper presents the method of online sequential learning machine with differential evolution algorithm to optimize Extreme Learning Machine and improve the diagnostic accuracy and generalization...
Existing web-services description is limited to the interface's type, parameters, and operation's definition and description, it is insufficient to describe the data-services in big data. Relative to the web-services, data-services is more fundamental, What's more important is to describe the characteristics and semantic attribute of data source. In this paper, used Scalable OWL-S (Ontology Web Language...
