Comparison of Methods for Estimating Temporal Topic Models From Primary Care Clinical Text Data: Retrospective Closed Cohort Study

open access: yesJMIR Medical Informatics, 2022
BackgroundHealth care organizations are collecting increasing volumes of clinical text data. Topic models are a class of unsupervised machine learning algorithms for discovering latent thematic patterns in these large unstructured

A New Formulation for Latent Class Models [PDF]

open access: yesSSRN Electronic Journal, 2014
Latent class, or finite mixture, modelling has proved a very popular, and relatively easy, way of introducing much-needed heterogeneity into empirical models right across the social sciences. The technique involves (probabilistically) splitting the population into a finite number of (relatively homogeneous) classes, or types.

Modeling factors to various drivers' actions due to vehicle malfunctions, the integrated latent class and latent variable model

open access: yesEngineering Reports, 2022
It is known that how individuals perceive the situation result in choices. However, it is unknown, how drivers process the information of vehicle malfunctions based on the situation at hand.

A hierarchical Bayesian network approach for linkage disequilibrium modeling and data-dimensionality reduction prior to genome-wide association studies

open access: yesBMC Bioinformatics, 2011
Background Discovering the genetic basis of common genetic diseases in the human genome represents a public health issue. However, the dimensionality of the genetic data (up to 1 million genetic markers) and its complexity make the statistical analysis a

Latent Structure Models for Analyzing Processes of Change a General Framework and a Latent Class Markov Chain Model [PDF]

open access: yesThe Egyptian Statistical Journal, 1992
This paper is a continuation and development of work on a group of latent structure models proposed by Lazarsfeld and Henry (1968) and Wiggins (1973) for analyzing processes of change over time. There have been problems associated with these models, see,

Analysis and modeling of trucks travel choice preference under differentiated charging

open access: yesShenzhen Daxue xuebao. Ligong ban, 2023
To study the impact of expressway differentiated charging on the travel choice behavior of truck drivers, this paper combines the multinomial logit (MNL) model, the nested logit (NL) model and the latent class model based on the theoretical framework of ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Epigenetic reprogramming of lineage switching in cancer

open access: yesFEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Emerging experimental and computational methods for studying redox‐regulated structural transitions

open access: yesFEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...
