This repository contains the code accompanying the ICCV 2021 paper "Meta Learning on a Sequence of Imbalanced Domains with Difficulty Awareness" Paper link:

Requirements to run the code:

---

1. Python 3.7
2. PyTorch 1.8.0
3. torchmeta 1.7.0
4. numpy 1.20.3
5. tqdm

Download dataset:

---

Download six datasets ( ['Quickdraw', 'MiniImagenet', 'Omniglot', 'CUB', 'Aircraft', 'Necessities']) from google drive here and put the dataset folder in the root directory of this project

Experiments on one domain sequence:

---

Usage for training Prototypical network with the Proposed Method of Memory Management with Domain Distribution and Difficulty Awareness

python train_protonet.py

Usage for training ANIL (MAML) with the Proposed Method of Memory Management with Domain Distribution and Difficulty Awareness

python train_ANIL.py

Note that ANIL-based method currently only contains the domain shift detection component for illustration, other components have not been cleaned yet, but they are almost the same as Protonet-based method.
