When Is 0.1% Enough? Analyzing the Combined Effects of Dimensionality Reduction and Quantization on Text Embedding Compression

arXiv:2606.01074v1 Announce Type: new Abstract: Recent high-performing text embedding models often output high-dimensional real-valued vectors, resulting in substantial storage and computational costs. To address this issue, compression methods based on dimensionality reduction or quantization have been proposed; however, the effects of combining dimensionality reduction and quantization have not been sufficiently investigated. In this paper, we systematically examine the effectiveness of compressing text embeddings by combining dimensionality reduction and quantization, using four MTEB task f

Why this matters
Why now

The proliferation of increasingly complex AI models necessitates efficient methods for managing their computational and storage requirements, making compression a critical area of research right now.

Why it’s important

Optimizing text embedding storage and computation through combined dimensionality reduction and quantization can significantly lower the cost and increase the scalability of AI applications for strategic readers.

What changes

The ability to deploy large text embedding models more efficiently will accelerate the development and adoption of AI technologies, especially in resource-constrained environments.
