Improvement Strategies for Few-Shot Learning in OCT Image Classification of Rare Retinal Diseases
Cheng-Yu Tai, Ching-Wen Chen, Chi-Chin Wu +6
This paper focuses on using few-shot learning to improve the accuracy of classifying OCT diagnosis images with major and rare classes. We used the GAN-based augmentation strategy a…
Dependencies in Item-Adaptive CAT Data and Differential Item Functioning Detection: A Multilevel Framework
Dandan Chen Kaptur, Justin Kern, Chingwei David Shin +1
Differential item functioning (DIF) detection is an important yet understudied problem in computerized adaptive testing (CAT). In this article, we proposed a two-level logistic mod…
Examining Differential Item Functioning (DIF) in Self-Reported Health Survey Data: Via Multilevel Modeling
Dandan Chen Kaptur, Yiqing Liu, Bradley Kaptur +4
Few health-related constructs or measures have received a critical evaluation in terms of measurement equivalence, such as self-reported health survey data. Differential item funct…
Multidimensional Cybersecurity Framework for Strategic Foresight
Cyril Onwubiko, Karim Ouazzane
Cybersecurity is now at the forefront of most organisational digital transformative agendas and National economic, social and political programmes. Hence its impact to society can…
Asymptotic harvesting of populations in random environments
Alexandru Hening, Dang H. Nguyen, Sergiu C. Ungureanu +1
We consider the harvesting of a population in a stochastic environment whose dynamics in the absence of harvesting is described by a one dimensional diffusion. Using ergodic optima…
Stochastic population growth in spatially heterogeneous environments: The density-dependent case
Alexandru Hening, Dang H. Nguyen, George Yin
This work is devoted to studying the dynamics of a structured population that is subject to the combined effects of environmental stochasticity, competition for resources, spatio-t…
