PWA-PEM for Latent Tree Model and Hierarchical Topic Detection
Web2 de jun. de 2024 · In this paper, we proposed an alternative way of performing a latent class analysis, which we called Latent Class Tree modeling. More specifically, we showed how to impose a hierarchical structure on the latent classes using the divisive LC analysis algorithm developed by Van der Palm et al. (2016). WebHierarchical latent tree analysis (HLTA) is recently proposed as a new method for topic detection. It differs fundamentally from the LDA-based methods in terms of topic definition, topic-document relationship, and learning method. It has been shown to discover significantly more coherent topics and better topic hierarchies. WebThe essence of latent class analysis (LCA) is to characterize the latent concept by analyzing those correlations. This is possible due to the assumption that the manifest variables are mutually independent given the latent variable, which can be intuitively interpreted as saying that the latent variable is the only reason for the correlations. can i take coq10 at night
