...Mixture models are used in a wide range of applications, including population structure (Pritchard, Stephens, and Donnelly 2000), document modeling (Blei, Ng, and Jordan 2003), speaker recognition (Reynolds, Quatieri, and Dunn 2000), computer vision (Stauffer and Grimson 1999), phylogenetics (Pagel…...

...…design preferences by extracting audio fromUGC in Bunboxing^ videos and applying IBMWatson’s Speech to Text (IBM2017) program to convert the audio into text transcriptions, which then could be classified and summarized according to the topic content with the LDA algorithm (Blei et al. 2003)....

...In order to overcome these shortcomings, probabilistic LSA (pLSA) (Hofmann, 1999) and Latent Dirichlet Allocation (LDA) (Blei et al., 2003; Blei, 2012) have been developed as extensions to the classic LSA idea....

...The most crucial LDA parameter is the number of topics to be extracted (Blei et al., 2003; Boyd-Graber et al., 2014)....

...The core idea behind LDA, first proposed by Blei et al. (2003), is an imaginary generative process that assumes that authors compose D documents by first choosing a discrete distribution of T topics to write about, and then drawing W words from a discrete distribution of words that are typical for…...

...Apart from descriptive purposes, topic models can also be used for explanatory or predictive purposes (Blei et al., 2003)....

...In the populartf-idf scheme (Salton and McGill, 1983), a basic vocabulary of “words” or “terms” is chosen, and, for each document in the corpus, a count is formed of the number of occurrences of each word....
