Shen et al. present Towards Backward-Compatible Representation Learning
Presented Towards Backward-Compatible Representation Learning — proposed BCT, which trains a new embedding model to be compatible with the old index, eliminating re-indexing
Why it matters
The first study to tackle the cost of embedding migration head-on. Framed as a problem the structural debt of having to re-embed the entire corpus every time the model is replaced
