Radar tracking and detection are always interfaced by unwanted clutter, so the research on clutter has significant meaning to the improvement of detection and tracking performance. Modeling and simulation is an important approach to study the clutter, and helpful to the development of detection theory and design of optimal detector. This paper introduces the research trend on radar clutter modeling...
Support vector machine is the highlight in machine learning. Also, performance evaluation and parameters selection for SVM model become an important issue to make it practically useful. In this paper, after investigating current evaluation index for pattern recognition, we introduced receiver operating characteristic curve into the performance evaluation. Area under receiver operating characteristic...
The actual financial time series is random walk process which is biased, and has significant fractal features and long-term memory effect. Research results also show the existence of low dimension chaos in stock market. Fractal dimension is the salient features of stock market chaos, and the next integer larger than correlation dimension is the number of the independent system variable which is required...
Microturbine generator (MTG) system is a clean, efficient, low cost and novel energy supply system and it is widely used in a variety of power generation and industrial applications. MTG dynamics are often complex and vary with operating point and ambient conditions, although the relationship of input-output is very simple, therefore conventional control law adopted cannot achieve expectant result...
