Mitigating Negative Flips via Margin Preserving Training

AAAI 2026technical

Minimizing inconsistencies across successive versions of an AI system is as crucial as reducing the overall error. In image classification, such inconsistencies manifest as negative flips, where an updated model misclassifies test samples that were previously classified correctly. This issue becomes

$\boldsymbol{\lambda}$-Orthogonality Regularization for Compatible Representation Learning

NeurIPS 2025poster

Retrieval systems rely on representations learned by increasingly powerful models. However, due to the high training cost and inconsistencies in learned representations, there is significant interest in facilitating communication between representations and ensuring compatibility across independentl…

Stationary Representations: Optimally Approximating Compatibility and Implications for Improved Model Replacements

CVPR 2024highlight

Learning compatible representations enables the interchangeable use of semantic features as models are updated over time. This is particularly relevant in search and retrieval systems where it is crucial to avoid reprocessing of the gallery images with the updated model. While recent research has sh…
