Em is what I always want to learn.AlgorithmThe first time I heard about hmm in NLP, I used the EM algorithm to solve the HMM parameter estimation problem. It is also used in the word alignment in the subsequent Mt. In Mitchell's book, we also
Mixed Gaussian model (mixtures of Gaussians) and EM algorithmThis discussion uses the desired maximization algorithm (expectation-maximization) for density estimation (density estimation).As with K-means, given the training sample, we will show the

EM is one of the algorithms that I've always wanted to learn deeply, the first time I heard it was in the HMM section of NLP class, in order to solve the hmm parameter estimation problem, the EM algorithm was used. The words in the MT later are also
Mixed Gaussian model and EM algorithmThis discussion uses the desired maximization algorithm (expectation-maximization) for density estimation (density estimation).As with K-means, given the training sample , we will show the implied category label.
For Oracle10grac constructs em, originally very easy thing, but it takes a long time to record down. MEMO.First, for example, the following error was reported:[[email protected] admin]$ emca-config dbcontrol dbstarted emca at 9:06:47 amem
In Mitchell's book, we also mentioned that EM can be used in Bayesian Networks.
The entire derivation process of EM is described below.1. Jenkins Inequality
Review some concepts in optimization theory. If F is a function with a definite field as a
One-time oracle em configuration experience and oracleem configuration experience
Configuring em for oracle10grac was originally a very simple task, but it took a long time to record it and forget it.
First, the following error is reported:

The Oracle10grac configuration of EM, originally a very simple thing, but it took a long time, recorded, Memo.The first is to report the following error:[[email protected] admin]$ emca-config dbcontrol dbstarted emca at 9:06:47 amem Configuration
