Backward-Compatible Aligned Representations via an Orthogonal Transformation Layer
Simone Ricci, Niccolò Biondi, Federico Pernici +1
Visual retrieval systems face significant challenges when updating models with improved representations due to misalignment between the old and new representations. The costly and…

Stationary Representations: Optimally Approximating Compatibility and Implications for Improved Model Replacements
Niccolò Biondi, Federico Pernici, Simone Ricci +1
Learning compatible representations enables the interchangeable use of semantic features as models are updated over time. This is particularly relevant in search and retrieval syst…
