Introduction of EM algorithmIn one of the EM algorithm-the problem is introduced in the issue of the coin, the object function of the model, mentioned that the maximum likelihood estimation of the implicit variable to be solved with the EM algorithm,

This chapter may be the most unclear part of Andrew Ng's story, why do you say so? This chapter focuses on the post-propagation (backpropagration, BP) algorithm, Ng spends more than half time talking about how to calculate the error term $\delta$,

Logistic regression is a classification algorithm which can deal with two-tuple classification and multivariate classification. Although its name contains "regression" two words, but not a regression algorithm. So why is there a misleading word for "

Supervised learningFor a house price forecasting system, the area and price of the room are given, and the axes are plotted by area and price, and each point is drawn.Defining symbols:\ (x_{(i)}\) represents an input feature \ (x\).\ (y_{(i)}\)

Introduction of EM algorithm In one of the EM algorithm-the problem is introduced in the issue of the coin, the object function of the model, mentioned that the maximum likelihood estimation of the implicit variable to be solved with the EM

The model of text subject LDA (i) LDA FoundationThe model of the text subject LDA (ii) The Gibbs sampling algorithm for LDA solutionLDA of the text subject model (iii) The variational inference EM algorithm for LDA solutionThis article is the third

The 9th Chapter EM algorithm and its generalization EM algorithm is an iterative algorithm, which is used for maximum likelihood estimation of probabilistic model parameters with implicit variables (hidden variable), or maximal posteriori

In English phonetics, the hardest thing for Chinese to learn is today's pair, theta and D. It looks strange, what a good side to do, speak to the tongue out, not a bit beautiful greasy. Indeed, in general, this tone has to be used to bite the tip of

Recently contacted with the PLSA model, it is necessary to use the desired maximization (expectation maximization) algorithm to solve the problem because the subject is introduced as an implicit variable in the model.Why an EM algorithm is
