Latent class model with application to speaker diarization [PDF]

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2019
In this paper, we apply a latent class model (LCM) to the task of speaker diarization. LCM is similar to Patrick Kenny’s variational Bayes (VB) method in that it uses soft information and avoids premature hard decisions in its iterations.

The Role of Trust in Explaining Food Choice: Combining Choice Experiment and Attribute Best–Worst Scaling [PDF]

open access: yesFoods, 2020
This paper presents empirical findings from a combination of two elicitation techniques—discrete choice experiment (DCE) and best−worst scaling (BWS)—to provide information about the role of consumers’ trust in food choice ...

Latent Class-Conditional Noise Model

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2023
Learning with noisy labels has become imperative in the Big Data era, which saves expensive human labors on accurate annotations. Previous noise-transition-based methods have achieved theoretically-grounded performance under the Class-Conditional Noise model (CCN).

Ridesourcing mode choice: A latent class choice model for UberX in Chile

open access: yesTransportation Research Interdisciplinary Perspectives, 2022
As shared mobility expands, ridesourcing has become its most popular manifestation. However, users’ mode choice has not yet been sufficiently explored. Thus, this study aims to model ridesourcing mode choice across different latent classes to ascertain ...

The Q-Matrix Anchored Mixture Rasch Model

open access: yesFrontiers in Psychology, 2021
Mixture item response theory (IRT) models include a mixture of latent subpopulations such that there are qualitative differences between subgroups but within each subpopulation the measure model based on a continuous latent variable holds.

Measurement Invariance and Differential Item Functioning Across Gender Within a Latent Class Analysis Framework: Evidence From a High-Stakes Test for University Admission in Saudi Arabia

open access: yesFrontiers in Psychology, 2020
The main aim of the present study was to investigate the presence of Differential Item Functioning (DIF) using a latent class (LC) analysis approach. Particularly, we examined potential sources of DIF in relation to gender.

The Latent Class Model as a Measurement Model for Situational Judgment Tests

open access: yesPsychologica Belgica, 2011
In a situational judgment test, it is often debatable what constitutes a correct answer to a situation. There is currently a multitude of scoring procedures. Establishing a measurement model can guide the selection of a scoring rule.

Effects of switching between production systems in dairy farming

open access: yesBio-based and Applied Economics, 2015
The increasing intensification of dairy farming in Europe has sparked an interest in studying the economic consequences of this process. However, empirically classifying farms as extensive or intensive is not a straightforward task.

The Use of Loglinear Models for Assessing Differential Item Functioning Across Manifest and Latent Examinee Groups [PDF]

open access: yes, 1990
Loglinear latent class models are used to detect differential item functioning (DIF). These models are formulated in such a manner that the attribute to be assessed may be continuous, as in a Rasch model, or categorical, as in Latent Class Mastery models.
