Normalized Approach to Find Optimal Number of Topics in Latent Dirichlet Allocation (LDA)

open access: closed, 2020
Feature extraction is one of the challenging works in the Machine Learning (ML) arena. The more features one able to extract correctly, the more accurate knowledge one can exploit from data. Latent Dirichlet Allocation (LDA) is a form of topic modeling used to extract features from text data.

Estimation of an Optimized Number of Topics by Consensus Soft Clustering Using NMF

Electronics and Communications in Japan, 2012
SUMMARYWe propose here a novel approach to exploring an optimized number of topics in a document set using consensus clustering based on nonnegative matrix factorization (NMF). It is useful to automatically determine the number of topics in a document set because various approaches to heuristic topic extraction determine it. Consensus clustering merges
