README

        
# What's this

Implementation of PReLUNet by chainer  

# Dependencies

    git clone https://github.com/nutszebra/prelu_net.git

    cd prelu_net

    git submodule init

    git submodule update

# How to run

    python main.py -g 0

# Details about my implementation

All hyperparameters and network architecture are the same as in [[1]][Paper] except for some parts.

* Data augmentation  

Train: Pictures are randomly resized in the range of [256, 512], then 224x224 patches are extracted randomly and are normalized locally. Horizontal flipping is applied with 0.5 probability.  

Test: Pictures are resized to 384x384, then they are normalized locally. Single image test is used to calculate total accuracy.  

* SPP net

Instead of spp, I use global average pooling.

* Learning rate schedule

Learning rate is divided by 10 at [150, 225] epoch. The total number of epochs is 300.
