Backbone Training

We use the same backbone network and training strategies as 'S2M2_R'. Please refer to https://github.com/nupurkmr9/S2M2_fewshot for the backbone training.

Extract and save features

After training the backbone as 'S2M2_R', extract features as below:

• Create an empty 'checkpoints' directory.

• Run:

python save_plk.py --dataset [miniImagenet/CUB] 

Or you can directly download the extracted features/pretrained models from the link:

After downloading the extracted features, please adjust your file path according to the code.

Evaluate our distribution calibration

To evaluate our distribution calibration method, run:

python evaluate_DC.py
