Overview

Can we aggressively trim down the complexity of pre-trained models, without damaging their downstream transferability?

Transfer Learning for Winning Tickets from Supervised and Self-supervised Pre-training

Downstream classification tasks.

Downstream detection and segmentation tasks.

Properties of Pre-training Tickets

Reproduce

Preliminary

Required environment:

  • pytorch >= 1.5.0
  • torchvision

Pre-trained Models

Pre-trained models are provided here.

imagenet_weight.pt # torchvision std model

moco.pt # pretrained moco v2 model (only contain encorder_q)

moco_v2_800ep_pretrain.pth.tar # pretrained moco v2 model (contain encorder_q&k)

simclr_weight.pt # (pretrained_simclr weight)

Task-Specific Tickets Finding

Remark. for both pre-training tasks and downstream tasks.
