Multi-label learning is popular in current research of machine learning areas, and there have already been many methods using label relationship to solve multi-label problems. However, the meaning of their relationship is not so obvious that it's hard for us to know the fact among labels. Besides, with the development of multi-label learning, hierarchical multi-label classification is a new research...
Dementia is one of the most common diseases in the elderly people. Experience shows that Microsoft's SenseCam can be an effective memory-aid device, as it helps users to improve recollecting an experience by creating visual lifelogs. Given the vast amount of images that are maintained in a visual lifelog, it is a significant challenge to deconstruct a sizeable collection of images into meaningful...
An LP (Linear Prediction) spectrum modification method is proposed based on linear extrapolation for different signal to noise ratio under the white noise environment. A direct modification on the noisy LP spectrum is employed, since the autocorrelation coefficients of the original speech are not available in some practical applications. The linear suppression rule is applied into the high-frequency...
This study was to investigate the diagnosis of DSCT pre-operation about the left ventricular function in complex congenital heart disease with diminished pulmonary blood flow in comparison of 2D-echocardiography. 50 patients scheduled for operation because of suspected or definited complex congenital heart disease with diminished pulmonary blood flow were examined by DSCT. The images were quantitatively...
The charge balance function is studied in Au + Au collisions at GeV using the STAR detector at the Relativistic Heavy-Ion Collider. Within the acceptance of the STAR TPC, it is found that the balance function is independent of the position of pseudorapidity windows with equal-size. It is also demonstrated for the first time at RHIC that the balance function divided...
In wireless sensor networks, sensor nodes are densely deployed for environmental monitoring, so the observation random data are highly correlated in space. This paper proposed a WSN data correlation model named OD Model based on spatial location according to the most universal mode of omnidirectional Boolean sensing. Both analysis and simulation results show that the accuracy estimation of OD Model...
The domain knowledge has a direct impact on the result of question - answering (Q & A) in the restricted domain question answering system (QA). In this paper, a method of answer extraction for domain Chinese question-and-answer (Q&A) is proposed, which based on the analysis of interrogative sentence and the answer type, carrying on the text retrieval with the help of the domain knowledge and...
