  • Update on 2024.05.14: I'm highly interested in extending EfficientTrain++ to CLIP-style models, multi-modal large language models, generative models (e.g., diffusion-based or token-based), and advanced visual self-supervised learning methods. I'm always open to discussions and potential collaborations. If you are interested, please kindly send an e-mail to me (wang-yl19@mails.tsinghua.edu.cn).

Overview

We present a novel curriculum learning approach for the efficient training of foundation visual backbones. Our algorithm, EfficientTrain++, is simple, general, yet surprisingly effective. As an off-the-shelf approach, it reduces the training time of various popular models (e.g., ResNet, ConvNeXt, DeiT, PVT, Swin, CSWin, and CAFormer) by 1.5−3.0× on ImageNet-1K/22K without sacrificing accuracy. It also demonstrates efficacy in self-supervised learning (e.g., MAE).

Highlights of our work

  • 1.5−3.0× lossless training or pre-training speedup on ImageNet-1K and ImageNet-22K. Practical efficiency aligns with theoretical performance. Both upstream and downstream performance are not affected.
  • Effective for diverse visual backbones, including ConvNets, isotropic/multi-stage ViTs, and ConvNet-ViT hybrid models. For example, ResNet, ConvNeXt, DeiT, PVT, Swin, CSWin, and CAFormer.
  • Dramatically improving the performance of relatively smaller models (e.g., on ImageNet-1K, DeiT-S: 80.3% -> 81.3%, DeiT-T: 72.5% -> 74.4%).
  • Superior performance across varying training budgets (e.g., training cost of 0 - 300 epochs or more).
  • Applicable to both supervised learning and self-supervised learning (e.g., MAE).
  • Optional techniques optimized for limited CPU/memory capabilities (e.g., cannot support high data pre-processing speed).
  • Optional techniques optimized for large-scale parallel training (e.g., 16-64 GPUs or more).
