ACE: Adaptative ChatGPT for Enterprise
Abstract
We present a novel framework named ACE (Adaptive ChatGPT for Enterprise) designed to tailor the responses generated by a Large Language Model (LLM) to meet the specific requirements of an enterprise, predicated upon a predetermined set of documents. The distinctive innovation within this framework resides in its capacity to effectively identify documents aligning with the specific needs of the enterprise.

Similarity search finds application in database systems handling complex data such as images or videos, which are typically represented by high-dimensional features and require specific indexing structures. This paper tackles the problem of better utilizing GPUs for this task. While GPUs excel at data parallel tasks such as distance computation, prior approaches in this domain are bottlenecked by algorithms that expose less parallelism, such as
k
-min selection, or make poor use of the memory hierarchy. We propose a novel design for
k
-selection. We apply it in different similarity search scenarios, by optimizing brute-force, approximate and compressed-domain search based on product quantization. In all these setups, we outperform the state of the art by large margins. Our implementation operates at up to 55 percent of theoretical peak performance, enabling a nearest neighbor implementation that is 8.5 × faster than prior GPU state of the art. It enables the construction of a high accuracy
k
-NN graph on 95 million images from the
Yfcc100M
dataset in 35 minutes, and of a graph connecting 1 billion vectors in less than 12 hours on 4 Maxwell Titan X GPUs. We have open-sourced our approach for the sake of comparison and reproducibility.
