Since the introduction of turbo codes in 1993, iterative decoding algorithms have seen tremendous use in telecommunications. Even before 1993 though, the expectation-maximization (EM) algorithm, an iterative procedure for producing maximum-likelihood (ML) estimates introduced in a unified form in 1978,...
面试的时候,特别是对面试 research 方面职位的人,我一个常见的问题是 EM(最早的文献是 1977 年 Dempster、Laird 和 Rubin 的Maximum likelihood from incomplete data via the EM algorithm),尽管切入点时常不同,但是感觉国内的学生(研究 machine learning)大部分还是停留在比较肤浅的角度,即便声称读过PRML也好EOSL也...
Full size table Table 2 reports the running times of various algorithms. It can be seen that the EML algorithm takes longer to run than EM-CDL and EM-ATCDL, and is computationally prohibitive (takes longer than 10 hours on an Intel (R) Core (TM) 2 desktop) when the pool size is k...
Section 5 contains a discussion on the advantages and disadvantages of EM algorithm. In Section 6, a non-linear dynamic process model is identified using proposed approach. Section 7 concludes the paper. Access through your organization Check access to the full text by signing in through your ...
The signal-processing algorithm for the analysis of particle-resolution EMBER spectra was executed in MATLAB with pca. Each identified EMBER particle from the particle segmentation was normalized to [0, 1] and then concatenated in an array for principal component analysis. The principal component ...
If no division and no multiplication instruction, use a non-restoring division algorithm. Similar optimizations apply to double-precision division. Integration and use emFloat provides all well-known floating-point-related API functions of C standard libraries, as well as floating-point-operation func...
In this appendix, we extend the proposed equalization algorithm for the case of correlated channel's paths. First, let us assume for simplicity we have only two paths in the channel and rewrite (6) in the concatenated form (B1) For the correlated case we can still have (B2) where now...
Three new algorithms (ECM, ECM(NR), and ECME) will be proposed with the advantages of the EM algorithm: easy implementation and numerical stability. Considering bias and mean squared error (MSE), simulations with different correlation values suggest that MLE performs similarly to the proposed ...
3. Last yet very important, is this algorithm. I’m not claiming to be a world class photographer but most of my photos have been deemed not worthy for market sale. I’ve seen the photos of the very popular photographers/contributors and I can say that most of my best photos are as ...
