Learning Word Vectors for Sentiment Analysis
ai.stanford.eduLatent Dirichlet Allocation (LDA; (Blei et al., 2003)) is a probabilistic document model that as-sumes each document is a mixture of latent top-ics. For each latent topic T, the model learns a conditional distribution p(wjT) for the probability that word w occurs in T. One can obtain a k-dimensional vector representation of words by first

www.statmodel.comConfirmatory factor analysis (CFA) is used to study the relationships between a set of observed variables and a set of continuous latent variables. When the observed variables are categorical, CFA is also referred to as item response theory (IRT) analysis (Fox, 2010; van der Linden, 2016).
