Expectation Maximization,hod used to obtain the local optima of these parameters of probabilistic graphical models with latent variables. This chapter introduces how to apply the EM algorithm in topic models such as PLSA. The foundation of EM algorithm is introduced in Sect. 4.1. The convergence of EM is introduced in Sect.

Distributed Training, to train such large-scale topic models encounters bottlenecks in computing efficiency and data storage. Therefore, it is necessary to develop distributed training mechanisms for topic models. In this chapter, we introduce distributed computing architectures in Sect. 7.1, followed by the distributed

Expectation Maximization,the EM algorithm in topic models such as PLSA. The foundation of EM algorithm is introduced in Sect. 4.1. The convergence of EM is introduced in Sect. 4.2 and the generalized expectation maximization (GEM) is discussed in Sect. 4.3. Finally, the applications of EM and GEM in topic models are explained in Sect. 4.4.
