EGA adapts frozen encoders for vector search with bounded OOD degradation

Researchers have introduced Euclidean Geodesic Alignment (EGA), a novel adapter for vector search systems that utilizes frozen encoders. EGA addresses the issue of performance degradation when encountering queries from unseen classes by employing a combination of zero initialization, local triplet loss, and hypersphere projection. This approach limits gradient updates to regions where local geometry is already correct, preserving the integrity of unseen class data while refining seen classes. AI
