Secure latent Dirichlet allocation [PDF]

open access: yesFrontiers in Digital Health
Topic modelling refers to a popular set of techniques used to discover hidden topics that occur in a collection of documents. These topics can, for example, be used to categorize documents or label text for further processing. One popular topic modelling

Latent Dirichlet Allocation modeling of environmental microbiomes. [PDF]

open access: yesPLoS Computational Biology, 2023
Interactions between stressed organisms and their microbiome environments may provide new routes for understanding and controlling biological systems. However, microbiomes are a form of high-dimensional data, with thousands of taxa present in any given ...

Latent Dirichlet Allocation in predicting clinical trial terminations [PDF]

open access: greenBMC Medical Informatics and Decision Making, 2019
Background This study used natural language processing (NLP) and machine learning (ML) techniques to identify reliable patterns from within research narrative documents to distinguish studies that complete successfully, from the ones that terminate ...

Latent Dirichlet allocation model for world trade analysis. [PDF]

open access: yesPLoS ONE, 2021
International trade is one of the classic areas of study in economics. Its empirical analysis is a complex problem, given the amount of products, countries and years.

LDA filter: A Latent Dirichlet Allocation preprocess method for Weka. [PDF]

open access: goldPLoS ONE, 2020
This work presents an alternative method to represent documents based on LDA (Latent Dirichlet Allocation) and how it affects to classification algorithms, in comparison to common text representation.

Discovering Tonal Profiles with Latent Dirichlet Allocation [PDF]

open access: yesMusic & Science, 2021
Music analysis, in particular harmonic analysis, is concerned with the way pitches are organized in pieces of music, and a range of empirical applications have been developed, for example, for chord recognition or key finding. Naturally, these approaches

Gaussian hierarchical latent Dirichlet allocation: Bringing polysemy back. [PDF]

open access: yesPLoS One, 2023
Topic models are widely used to discover the latent representation of a set of documents. The two canonical models are latent Dirichlet allocation, and Gaussian latent Dirichlet allocation, where the former uses multinomial distributions over words, and the latter uses multivariate Gaussian distributions over pre-trained word embedding vectors as the ...

Discovering Computer Science Research Topic Trends using Latent Dirichlet Allocation

open access: goldJOIN: Jurnal Online Informatika, 2021
Before conducting a research project, researchers must find the trends and state of the art in their research field. However, that is not necessarily an easy job for researchers, partly due to the lack of specific tools to filter the required information

A Zero-Inflated Latent Dirichlet Allocation Model for Microbiome Studies [PDF]

open access: yesFrontiers in Genetics, 2021
The human microbiome consists of a community of microbes in varying abundances and is shown to be associated with many diseases. An important first step in many microbiome studies is to identify possible distinct microbial communities in a given data set
