In the distributed processing, where common labeled data may be not available for designing classifier ensemble, however, an ensemble solution is necessary, traditional fixed decision aggregation could not account for class prior mismatch or classifier dependencies in electronic technology. Previous transductive learning strategies have several drawbacks, e.g., feasibility of the constraints was not guaranteed and heuristic learning was applied. We overcome these problems by developing improved iterative scaling (IIS) algorithm for optimal solution. This method is shown to achieve improved decision accuracy over the earlier approaches in electronic technology

说明：  对信号进行频域特征提取，先通过傅里叶变换得到信号频谱，再计算频谱特征，包括重心频率，均方频率和频率方差(Firstly, the frequency spectrum of the signal is obtained by Fourier transform, and then the spectrum characteristics, including center of gravity frequency, mean square frequency and frequency variance, are calculated.)
