Mathematical modeling of triphasic viral dynamics in patients with HBeAg-positive chronic hepatitis B showing response to 24-week clevudine therapy. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Modeling of short-term viral dynamics of hepatitis B with traditional biphasic model might be insufficient to explain long-term viral dynamics.

Analysis of Categorical Data with the R Package confreq

open access: yesPsych, 2021
The person-centered approach in categorical data analysis is introduced as a complementary approach to the variable-centered approach. The former uses persons, animals, or objects on the basis of their combination of characteristics which can be ...

Hidden Markov models as priors for regularized nonnegative matrix factorization in single-channel source separation [PDF]

open access: yes, 2012
We propose a new method to incorporate rich statistical priors, modeling temporal gain sequences in the solutions of nonnegative matrix factorization (NMF). The proposed method can be used for single-channel source separation (SCSS) applications.

Porting concepts from DNNs back to GMMs [PDF]

open access: yes, 2013
Deep neural networks (DNNs) have been shown to outperform Gaussian Mixture Models (GMM) on a variety of speech recognition benchmarks. In this paper we analyze the differences between the DNN and GMM modeling techniques and port the best ideas from the ...

Demand Analysis of Termite Control Service in Jakarta

open access: yesJurnal Sylva Lestari, 2020
Termite is an economically important pest species in the pest control industry and considered as one of the urban pests. Although it had caused a great loss, only a few studies on termite control demand were found.

Non-linear modeling parameters for new construction RC columns

open access: yesFrontiers in Built Environment, 2023
Modeling parameters (MP) of reinforced concrete columns are a critical component of performance-based seismic assessment methodologies because in these approaches damage is estimated based on element deformations calculated using non-linear models.

Phi-divergence statistics for the likelihood ratio order: an approach based on log-linear models

open access: yes, 2014
When some treatments are ordered according to the categories of an ordinal categorical variable (e.g., extent of side effects) in a monotone order, one might be interested in knowing wether the treatments are equally effective or not.

Integrating Differential Evolution Optimization to Cognitive Diagnostic Model Estimation

open access: yesFrontiers in Psychology, 2018
A log-linear cognitive diagnostic model (LCDM) is estimated via a global optimization approach- differential evolution optimization (DEoptim), which can be used when the traditional expectation maximization (EM) fails.

Multimethod Latent Class Analysis

open access: yesFrontiers in Psychology, 2015
Correct and, hence, valid classifications of individuals are of high importance in the social sciences as these classifications are the basis for diagnoses and / or the assignment to a treatment.
