Kaggle Competitions
There are plenty of courses and tutorials that can help you learn machine learning from scratch but here in GitHub, I want to solve some Kaggle competitions as a comprehensive workflow with python packages. After reading, you can use this workflow to solve other real problems and use it as a template.

Data setup
- In
scripts/train/conf/fewshots.yaml, specify the location of your custom$DATASET_PATH(data.root_dir). - Download Omniglot, CIFAR-FS and miniImageNet the above format. Original datasets from here and here.
- Download and extract one or more datasets in your custom
$DATASET_PATHfolder, the code assumes the following structure (example):
$DATASET_PATH
├── miniimagenet
│ ├── data
│ │ ├── n01532829
| | |── ...
│ │ └── n13133613
│ ├── splits

Repo setup (with Conda)
- Set up conda environment:
conda env create -f environment.yml. source activate fsrr- Install torchnet:
pip install git+https://github.com/pytorch/[email protected]. - Install the repo package:
pip install -e . source deactivate fsrr
Run
scripts/train/experiments.sh contains all the experiments of the paper (train+eval) in blocks of three lines, e.g.
expm_folder=mini_r2d2
python run_train.py --log.exp_dir $expm_folder --data.dataset miniimagenet --data.way 16 --model.drop 0.1 --base_learner.init_adj_scale 1e-4
python ../eval/run_eval.py --data.test_episodes 10000 --data.test_way 5 --data.test_shot 1 --model.model_path ../train/results/$expm_folder/best_model.1shot.t7
python ../eval/run_eval.py --data.test_episodes 10000 --data.test_way 5 --data.test_shot 5 --model.model_path ../train/results/$expm_folder/best_model.5shot.t7
