一种流形学习算法（很好用），对信号进行频谱分析及滤波，阵列信号处理的高分辨率估计，是机器学习的例程，本科毕设要求参见标准测试模型，最大似然（ML）准则和最大后验概率（MAP）准则。- A fluid manifold learning algorithm (good use), The signal spectral analysis and filtering, High-resolution array signal processing estimates, Machine learning routines, Undergraduate complete set requirements refer to the standard test models, Maximum Likelihood (ML) criteria and maximum a posteriori (MAP) criterion.
