A Spatio-Temporal Switchable Data Prefetcher for Convolutional Neural Networks

Jang, J., Kim, H., & Lee, H. (2023, October 25).

By: J. Jang *, H. Kim * & H. Lee n

author keywords: Data prefetching; spatio-temporal prefetcher; convolutional neural neworks
topics (OpenAlex): Neural Networks and Applications; Advanced Neural Network Applications; Generative Adversarial Networks and Image Synthesis
TL;DR: A spatio-temporal switchable data prefetcher that can adapt to the locality characteristics of CNN models and improves system performance by 33.8% over a baseline with no data prefetcher and 21% over the best-performing prior spatio-temporal prefetcher. (via Semantic Scholar)
