This novel study developed an option-operation suggestion model by applying integrated artificial intelligence technique, extending learning classifier system (XCS), which incorporates reinforcement machine learning method to the dynamical problems to the behavior finance. Due to the history of Behavior Finance, many researches have found that the shape of(More)
A method of motion status estimation of airborne synthetic aperture radar (SAR) platform in short subapertures via parametric sparse representation is proposed for high-resolution SAR image autofocusing. The SAR echo is formulated as a jointly sparse signal through a parametric dictionary matrix, which converts the problem of SAR motion status estimation(More)
Due to the lack of natural resources, the majority of energy in many countries must depend on import, and the corresponding cost is expensive and affected by international market fluctuation and control. In recent years, an intelligent micro-grid system composed of renewable energy sources is becoming one of the interesting research topics. The forecasting(More)
In this paper, a parametric sparse representation (PSR) method is proposed for refocusing of moving targets in synthetic aperture radar (SAR) images. In regular SAR images, moving targets are defocused due to unknown motion parameters. Refocusing of moving targets requires accurate phase compensation of echo data. In the proposed method, the region of(More)
In recent years, an intelligent micro-grid system composed of renewable energy sources is becoming one of the interesting research topics. The success design of daily load forecasting enables the intelligent micro-grid system to manipulate an optimized loading and unloading control by measuring the electrical supply for achieving the best economical and(More)
In recent years, an intelligent micro-grid system composed of renewable energy sources is becoming one of the interesting research topics. The success design of long-term load forecasting (LTLF) enables the intelligent micro-grid system to manipulate an optimized loading and unloading control by measuring the electrical supply for achieving the best(More)
In order to reduce the amount of echo data and achieve a wider observation swath, a parametric sparse representation method for the motion parameter estimation of ground moving targets is proposed with low pulse repetition frequency (PRF). First, the displaced phase center antenna technique is introduced to cancel the clutters. Second, since range cell(More)
At least one (n, k) double-error-correcting binary BCH code of length IZ = 2” 1 is available for any integer m > 3 [3,5]. Let (Y be a primitive element in GF(2m). The generator polynomial g(X) of the BCH code is then considered a:5 the lowest degree polynomial, which has LY, a’, a,3 and CY~ as its roots. Let Q,(X) and Q,(X) be the minimum distinct(More)
