Correcting Mean Bias in Text Embeddings: A Refined Renormalization with Training-Free Improvements on MMTEB
Xingyu Ren, Youran Sun, Haoyu Liang
We find that current sentence-embedding models produce outputs with a consistent bias: every embedding decomposes as , where the mean is near-identical across…
