Combining Color and Spatial Image Features for Unsupervised Image Segmentation with Mixture Modelling and Spectral Clustering

open access: yesMathematics, 2023
The demand for accurate and reliable unsupervised image segmentation methods is high. Regardless of whether we are faced with a problem for which we do not have a usable training dataset, or whether it is not possible to obtain one, we still need to be ...

Pedigree analysis and estimates of effective breeding size characterize sea lamprey reproductive biology

open access: yesEvolutionary Applications, 2022
The sea lamprey (Petromyzon marinus) is an invasive species in the Great Lakes and the focus of a large control and assessment program. Current assessment methods provide information on the census size of spawning adult sea lamprey in a small number of ...

A near‐DC measurement and modelling of low‐frequency noise in electronic components

open access: yesIET Science, Measurement & Technology, 2023
Low‐frequency noise, generated inherently by the number or mobility fluctuation of carriers, is a crucial concern for the design of analog and digital circuits.

A shift in strategy or “error”? Strategy classification over multiple stochastic specifications [PDF]

open access: yesJudgment and Decision Making, 2011
We present a classification methodology that jointly assigns to a decision maker a best-fitting decision strategy for a set of choice data as well as a best-fitting stochastic specification of that decision strategy.

Mixture-Based Probabilistic Graphical Models for the Label Ranking Problem

open access: yesEntropy, 2021
The goal of the Label Ranking (LR) problem is to learn preference models that predict the preferred ranking of class labels for a given unlabeled instance. Different well-known machine learning algorithms have been adapted to deal with the LR problem. In

Conceptualizing and Measuring Appetite Self-Regulation Phenotypes and Trajectories in Childhood: A Review of Person-Centered Strategies

open access: yesFrontiers in Nutrition, 2021
This review uses person-centered research and data analysis strategies to discuss the conceptualization and measurement of appetite self-regulation (ASR) phenotypes and trajectories in childhood (from infancy to about ages 6 or 7 years). Research that is

A Bayesian latent mixture model approach to assessing performance in stock-flow reasoning

open access: yesJudgment and Decision Making, 2017
People often perform poorly on stock-flow reasoning tasks, with many (but not all) participants appearing to erroneously match the accumulation of the stock to the inflow – a response pattern attributed to the use of a “correlation heuristic”. Efforts to
