Fractal approach for determining the optimal number of topics in the field of topic modeling.
Journal of Physics: Conference Series, 2019 In this paper we apply multifractal formalism to the analysis of statistical behaviour of topic models under condition of varying number of topics. Our analysis reveals the existence of two self-similar regions and one transition region in the function of density-of-states depending on the number of topics.

Efficient Processing of Spatial Joins Using R-Trees [PDF]
, 1993 : In this paper, we show that spatial joins are very suitable to be processed on a parallel hardware platform. The parallel system is equipped with a so-called shared virtual memory which is well-suited for the design and implementation of parallel ...

Improved Parsimonious Topic Modeling Based on the Bayesian Information Criterion
Entropy, 2020 In a previous work, a parsimonious topic model (PTM) was proposed for text corpora. In that work, unlike LDA, the modeling determined a subset of salient words for each topic, with topic-specific probabilities, with the rest of the words in the ...
