In‐Situ Zinc‐Organic Coordination Domains Inside Polyurethane Coatings for Superior Corrosion Protection of Mild Steel

Corrosion causes over US $2.5 trillion in annual economic losses, driving the need for protective polymer coatings that combine barrier effectiveness with active inhibition. Conventional ex‐situ mixing MOFs into polymer matrices often suffer from particle aggregation and poor interfacial adhesion, resulting in loca...

ICON decomposition: Multivariate concept auditing reveals shortcuts that neural networks rely on

This work reframe shortcut auditing as a decomposition of the variance of intermediary representations with Independent Canonical cONcepts (ICON), which separates learned shortcuts from merely correlated concepts, which it confirms with independent validation checks.

ICON Decomposition: Auditing deep neural networks for shortcuts by decomposing layer-wise representations using concepts

Deep neural networks often exploit spurious associations, a failure known as shortcut learning. Before deployment, models should be audited for reliance on a set of concepts, such as acquisition artifacts or demographics. Current methods, such as linear probes and concept activation vectors, measure reliance by asking...

Beyond Decodability: Do Acoustic Factors Drive Predictions in Speech-Based Alzheimer's Assessment?

It is argued that intervention-based robustness tests should become standard for trustworthy clinical speech models and show that high predictive performance and the absence of a significant diagnostic-group difference in a measured acoustic factor are not sufficient for robustness.

Controlling for Omitted Variable Bias in Deep Neural Networks

This work introduces an estimation procedure that refits the final layer of a pre-trained network to include covariate effects, and shows how these effects can be orthogonalised with respect to covariates to exclude their mediated effects and that model predictions can be marginalised over the covariate distribution to...

ICON decomposition : Auditing deep neural networks with multivariate, variance-based concept-level explanations

CON decomposition is introduced, which quantifies how much of a layer's variance each concept explains given all other concepts and the outcome, and how much none of them explains, yielding layer-comparable, calibrated scores that suppress false positives.
