A novel fault detection method based on margin statistics of generalized non-negative matrix factorization (GNMF) is proposed. The construction of traditional process monitoring method based on multivariate statistical that neglects the correlation relation and feature distribution of latent variables at different sampling times, and the method also need to assume that latent variables satisfy a particular...
Robots are typically equipped with multiple complementary sensors such as cameras and laser range finders. Camera generally provides dense 2D information while range sensors give sparse and accurate depth information in the form of a set of 3D points. In order to represent the different data sources in a common coordinate system, extrinsic calibration is needed. This paper presents a pipeline for...
As legged robots are suitable to be used in unstructured environments, it becomes a popular field of research nowadays. In this paper, the development of quadruped robots is summarized. And several typical and recent robot systems are addressed in details, such as HyQ series, StarlETH, ANYmal, MIT Cheetah and BigDog, etc. Furthermore, some key techniques of environment perception for quadruped robots,...
Exploiting linguistic features is necessary on sentiment analysis in natural language processing. This paper proposes a novel approach on exploiting linguistic features and SVMperf based semantic classification. The innovation is that it uses the dependency relationship to do the linguistic feature extraction. In order to reduce the computational complexity, this paper uses the X2 (chi-square) and...
The image annotation and retrieval are significant for semantic image retrieval that needs to establish the relations between linguistic labels and images. So the probabilistic formulation for semantic labeling is introduced to solve them. In addition, relevance feedback can improve the retrieval performance efficiently in the content-based image retrieval (CBIR). In this paper, we proposed a new...
The content-based image retrieval (CBIR) system aims at searching and browsing the large image digital libraries based on automatically derived imagery features. This paper introduces two algorithms based on the normalized cut for images clustering. We extract the color and texture features for computing the distance between the images, and take advantage of the bipartition method and minimum spanning...
In this paper, a networked control system for a biomimetic robot fish is introduced. The whole system includes four parts: a network camera which is embedded with FTP and Web server and used as a local sensor; a remote computer which works as a networked controller and obtains sensor information from the network camera, processes the information, generates instructions for the robot fish, and sends...
