Imbalance‐Aware Credit Card Fraud Detection Using Multi‐Autoencoders and Generative Ensemble Learning

Expert Systems, Volume 43, Issue 5, May 2026.
ABSTRACT Credit card fraud detection remains a challenging research problem due to the class imbalance issue caused by the rarity of fraudulent transactions. Classical oversampling techniques such as SMOTE, ADASYN and their variants help balance data but do not reflect the nonlinear structure of real‐world fraud, leading to poor generalization.

Uncovering Heart Rate Response Patterns to Threat Pictures Through Deep Latent Representation Learning with a Variational Autoencoder

Psychophysiology, Volume 63, Issue 5, May 2026.
ABSTRACT Group‐level averaging of psychophysiological data often obscures meaningful individual differences, masking response patterns that may explain variability in behavior and central nervous system activity. Identifying such patterns is particularly relevant in heart rate (HR) responses to threat, where subtle variations may reflect distinct ...
