DAEI pairs a residual denoising autoencoder, trained unsupervised via Stein's unbiased risk estimate with no access to clean embedding targets, with generative text inversion. It gets roughly 154% relative BLEU improvement over the prior inversion baseline and 32 to 60% gains in token-level F1 and ROUGE-L against noised embeddings. (arXiv 2608.18610) If you're publishing perturbed embeddings from a vector store on the theory that noise makes them safe, that theory just got a lot weaker.
