Image fusion based on expectation maximization algorithm and steerable pyramid
In this paper, a novel image fusion method based on the expectation maximization (EM) algorithm and steerable pyramid is proposed. The registered images are first decomposed by using steerable pyramid. The EM algorithm is used to fuse the image components in the low frequency band. The selection method involving the informative importance measure is applied to those in the high frequency band. The final fused image is then computed by taking the inverse transform on the composite coefficient rep

Evolutionary tree reconstruction using structural expectation maximization and homotopy
The evolutionary tree reconstruction algorithm called SEMPHY using structural expectation maximization (SEM) is an efficient approach but has local optimality problem. To improve SEMPHY, a new algorithm named HSEMPHY based on the homotopy continuation principle is proposed in the present study for reconstructing evolutionary trees. The HSEMPHY algorithm computes the condition probability of hidden variables in the structural through maximum entropy principle. It can reduce the influence of the i

em算法matlab代码实现-Expectation-Maximization Matlab中的期望最大化算法
【源码免费下载链接】:https://renmaiwang.cn/s/gf78r 该Matlab程序开发了一个实现Expectation-Maximization(EM)算法的系统,并在二维测试数据集中进行了性能评估。Expectation-Maximization(EM)算法是一种用于基于存在潜在变量但无法直接观测的情况来估计统计模型参数的迭代优化方法。其工作原理包括交替执行期望(E)步骤和最大化(M)步骤:在E步中,利用当前参数估计计算潜在变量的条件概率期望;在M步中,则通过最大化该期望值得到新的参数估计值。这一过程不断重复直至收敛。在这个具体案例中,首先生成了两个正态分布的数据集,并对数据进行了真实标注。随后,在无法观察标签的情况下,重新随机分配标签并运行EM算法进行模型训练。经过迭代优化后,EM算法成功地将数据划分为两组,并估计出了每个正态分布的参数(均值和协方差矩阵)。具体结果如下:迭代1次时误差为1.7244,最终收敛到mu1=[1.2662, 1.7053]和mu2=[3.6623, 3.0902]的参数估计。
