Stable Global Weighting of Flow Mixtures using Simplex Exponential Moving Average

Benjamin Wiriyapong, Oktay Karakus, Can Eyupoglu +1

Normalising flows provide a powerful variational family for approximate inference, yet individual architectures often fail to generalise across heterogeneous posterior geometries.…

Sequential Feature Selection for Efficient Landslide Segmentation from Multi-Spectral Data

Arsalaan Ahmad, Oktay Karakus, Paul L. Rosin

Landslide detection from satellite imagery has advanced through deep learning, yet most models rely on large, highly correlated spectral-topographic inputs whose contributions rema…

The Sim-to-Real Gap in MRS Quantification: A Systematic Deep Learning Validation for GABA

Zien Ma, S. M. Shermer, Oktay Karakuş +1

Magnetic resonance spectroscopy (MRS) is used to quantify metabolites in vivo and estimate biomarkers for conditions ranging from neurological disorders to cancers. Quantifying low…

What If They Took the Shot? A Hierarchical Bayesian Framework for Counterfactual Expected Goals

Mikayil Mahmudlu, Oktay Karakuş, Hasan Arkadaş

This study develops a hierarchical Bayesian framework that integrates expert domain knowledge to quantify player-specific effects in expected goals (xG) estimation, addressing a li…

Adaptive Heterogeneous Mixtures of Normalising Flows for Robust Variational Inference

Benjamin Wiriyapong, Oktay Karakuş, Kirill Sidorov

Normalising-flow variational inference (VI) can approximate complex posteriors, yet single-flow models often behave inconsistently across qualitatively different distributions. We…
