The EM algorithm is used to find (locally) maximum likelihood parameters of a statistical model in cases where the equations cannot be solved directly. Typically these models involve latent variables in addition to unknown parameters and known data observations. That is, either there are missing val...

To improve the algorithm efficiency, a stochastic step is incorporated into the E-step based on data augmentation, whereas the M-step is solved by the method of conditional maximization. A variation on Bayesian information criterion (BIC) is also proposed to compare models with different number ...

自动驾驶不能通过重规则 (heavy-decision-based algorithm) 来实现,最好的做法还是通过优化来实现。 这个示例中,进行了两次迭代 (两轮 EM 迭代)。通常,环境越复杂,计算迭代时间越复杂,所以优化问题是一个没有时间收敛上限的问题。 In general, the more complicated the environment is, the the more steps that ...

weights are cell type proportions. A standard EM algorithm can be used to estimate the parameters of this mixture of regression model. From our exploratory analysis, we found the estimation may be unstable when two or more cell types have highly correlated cell type-specific DNA methylation. To...
In this section, a high purity distillation column is used to test the performance of the multiple model approach based on the EM algorithm. It has been shown that the purer the products get, the more nonlinear the system becomes [20]. A distillation column is also a typical example for ...
If you open the Project settings and go to MCU, memory you will see the flash algorithm listed next to the flash memory. It seemed that this particular algorithm didn't exist. FTFE_2K_K32L3A60_cm4.cfx If you delete this algorithm from the memory setup you can select one in the ...
Instead of letting InDesign replace the linked story wholesale, it applies a complex algorithm behind the scenes to merge the changes made to the external document since the last update into the current InDesign story contents (and to detect any conflicts). We call this the “magic merge-...
