# A Closer Look at Few-shot Classification
This repo contains the reference source code for the paper [A Closer Look at Few-shot Classification](https://arxiv.org/abs/1904.04232) in International Conference on Learning Representations (ICLR 2019). In this project, we provide a integrated testbed for a detailed empirical study for few-shot classification.

## Enviroment
- Python3
- [Pytorch](http://pytorch.org/) before 0.4 (for newer vesion, please see issue #3 )
- json
## Getting started
### CUB
* Change directory to `./filelists/CUB`
* run `source ./download_CUB.sh`
### mini-ImageNet
* Change directory to `./filelists/miniImagenet`
* run `source ./download_miniImagenet.sh`
(WARNING: This would download the 155G ImageNet dataset. You can comment out correponded line 5-6 in `download_miniImagenet.sh` if you already have one.)
### mini-ImageNet->CUB (cross)
* Finish preparation for CUB and mini-ImageNet and you are done!
### Omniglot
* Change directory to `./filelists/omniglot`
* run `source ./download_omniglot.sh`
### Omniglot->EMNIST (cross_char)
* Finish preparation for omniglot first
* Change directory to `./filelists/emnist`
* run `source ./download_emnist.sh`
### Self-defined setting
* Require three data split json file: 'base.json', 'val.json', 'novel.json' for each dataset
* The format should follow
{"label_names": ["class0","class1",...], "image_names": ["filepath1","filepath2",...],"image_labels":[l1,l2,l3,...]}
See test.json for reference
* Put these file in the same folder and change data_dir['DATASETNAME'] in configs.py to the folder path
## Train
Run
```python ./train.py --dataset [DATASETNAME] --model [BACKBONENAME] --method [METHODNAME] [--OPTIONARG]```
For example, run `python ./train.py --dataset miniImagenet --model Conv4 --method baseline --train_aug`
Commands below follow this example, and please refer to io_utils.py for additional options.
## Save features
Save the extracted feature before the classifaction layer to increase test speed. This is not applicable to MAML, but are required for other methods.
Run
```python ./save_features.py --dataset miniImagenet --model Conv4 --method baseline --train_aug```
## Test
Run
```python ./test.py --dataset miniImagenet --model Conv4 --method baseline --train_aug```
## Results
* The test results will be recorded in `./record/results.txt`
* For all the pre-computed results, please see `./record/few_shot_exp_figures.xlsx`. This will be helpful for including your own results for a fair comparison.
## References
Our testbed builds upon several existing publicly available code. Specifically, we have modified and integrated the following code into this project:
* Framework, Backbone, Method: Matching Network

* Omniglot dataset, Method: Prototypical Network

## FAQ
* Q1 Why some of my reproduced results for CUB dataset are around 4~5% with you reported result? (#31, #34, #42)
* A1 Sorry about my reported the results on the paper may run in different epochs or episodes, please see each issue for details.
* Q2 Why some of my reproduced results for mini-ImageNet dataset are around 1~2% different with your reported results? (#17, #40, #41 #43)
* A2 Due to random initialization, each training process could lead to different accuracy. Also, each test time could lead to different accuracy.
* Q3 How do you decided the mean and the standard variation for dataset normalization? (#18, #39)
* A3 I use the mean and standard variation from ImageNet, but you can use the ones calculated from your own dataset.
* Q4 Do you have the mini-ImageNet dataset available without downloading the whole ImageNet? (#45 #29)
* A4 You can use the dataset here https://github.com/oscarknagg/few-shot, but you will need to modify filelists/miniImagenet/write_miniImagenet_filelist.py.
