During the course of ship machinery condition monitoring, it is universal that the number of normal condition samples is greater than the number of fault samples because the factors of test difficult or expensive testing costs. In the passive learning method to train the classifier using the all normal samples , it will not only lead to too much training time and even NP problem for some machine learning...
Remote sensing technology has many advantages in the city development and using remote sensing technology to monitor urban growth has become a trend. Various remote sensing data were engaged in monitoring the spatial and temporal processes of urban expansion and land use change. The CBERS has been applied in many fields. Based on multi-temporal CBERS imageries, the research extracted the urban built-up...
