How to Reproduce Baseline

It consists of two steps:

• Step1: Base training

  • use all the images of base classes to train a base model.
  • use validation set to select the best model.

• Step2: Meta Testing:

  • use best model from step1.

An example of CUB dataset with Conv4

# base training
python ./tools/classification/train.py \
  configs/classification/baseline/cub/baseline_conv4_1xb64_cub_5way-1shot.py

# meta testing
python ./tools/classification/test.py \
  configs/classification/baseline/cub/baseline_conv4_1xb64_cub_5way-1shot.py \
  work_dir/baseline_conv4_1xb64_cub_5way-1shot/best_accuracy_mean.pth

Note:

• All the result are trained with single gpu.
• The base training of 1 shot and 5 shot use same training setting, but different validation setting.
