24409 该方法通过联合Dirichlet过程混合与Bayes SVM模型，将信号空间划分成若干局部区域，然后在每一局部区域学习一个独立的极化检测器，并将各局部检测器进行组合实现全局多极化散射机理的目标检测。 By assembling a set of local polarimetric detectors that based on single polarimetric scattering mechanism, a global multiple polarimetric scattering mechanisms detector is obtained.

24412 该模型由于采用共轭先验分布，因而可以利用Gibbs采样方法进行高效求解。 Thanks to the conjugate property, the parameters in both of models can be inferred efficiently via the Gibbs sampler.
