pip install -r requirements.txt

Dataset

We will be using a dataset containing 200 different classes of birds adapted from the CUB-200-2011 dataset. Download the training/validation/test images from here. The test image labels are not provided.

Training and validating your model

Crop the image

Run the jupyter crop_bird

Extract the features

Git clone the repo https://github.com/richardaecn/cvpr18-inaturalist-transfer

Run it for the global images and the cropped images

Evaluate

Run main&evaluation_Regression.py

Resultats are :

	Linear Regression	Perceptron
Validation set	0.94175	0.95151
Test set	0.90322	0.90322
