Hierarchical-Bilinear-Pooling_Resnet_Pytorch

A reimplementation of Hierarchical Bilinear Pooling for Fine-Grained Visual Recognition in Resnet.

Requirements

• python 2.7
• pytorch 0.4.1

Train

Step 1.

• Download the resnet pre-training parameters.

• Download the CUB-200-2011 dataset. CUB-download

Step 2.

• Set the path to the dataset and resnet parameters in the code.

Step 3. Train the fc layer only.

• python train_firststep.py

Step 4. Fine-tune all layers. It gets an accuracy of around 86% on CUB-200-2011 when using resnet-50.

• python train_finetune.py

If you are interested in this code, you can continue to adjust the model structure, and try more resnet models, you should get better results.
