In this paper, new active learning methods are proposed to filter Chinese spam. It is time-consuming and expensive to label the spam emails in the large datasets. Active learning methods can conspicuously reduce labeling cost by identifying informative examples and speed up online Logistic Regression filter. The experiments illustrate that our methods not only decrease the number of label requests,...
According to the Traditional Chinese Medicine (TCM) theory, there are a number of TCM syndromes closely related to the sub-health status. In this paper, a personal sub-health status diagnosing prototype system, which acquires users' answers from health-related questions list, head images and videos, to give the diagnosis about the users' health states. The system can infer users' syndromes named in...
A formal approach to automatically building a regression test suite whose tests are guaranteed to exercise a given set of system changes is proposed. Given a test and a change, the approach analyzes the test description to provably predict whether or not the test will exercise the change. Adaptive tests whose descriptions involve multiple control paths and support values over commonly used data types...
PAUSMPW program and PMAUSM+up program based on improved MAUSM+up scheme are developed by the original three-dimensional viscous flow calculation program PTVD through studying high accuracy schemes, such as TVD, AUSM family schemes and son on. These programs are used for numerical calculation of the NASA high speed test and MARKII type blade 5411 test, and their viscous flow fields are analyzed. Compared...
It is key that school's competitiveness is put up by quality of training engineering creative talents in ordinary universities and colleges. By analysis of teaching ideas, objects of training talents, cooperative education mode of production and research and construction and management of the curriculum system, we can improve the quality of creative talents.
Based on the features of the Chemical Engineering & Technology, the experiment content, teaching materials and construction of teaching team are discussed in paper.
The dynamics of the local field neural networks have been studied extensively, and many good results have been obtained. It should be pointed out that, the global robust stability for the static neural networks with time-delays received very little attention despite its practical importance. Based on the fixed point theory, Lyapunov functional and differential inequality technique, a new criterion...
The dynamics of the local field neural networks have been studied extensively, and many good results have been obtained. It should be pointed out that, the global robust stability for the static neural networks with time-delays received very little attention despite its practical importance. In this paper, by using the topological degree theory M-matrix theory and the linear differential inequality...
LSB is a classical algorithm of information hiding in the spatial domain. Although it has high capacity of information hiding, the robustness is weakening. Considering the robustness and security of information hiding, a new spatial domain image information hiding algorithm (HSBH) is proposed, the algorithm improves robust and security by interval set and chaos located. Experimental results indicate...
