Transfer Learning Suite in Keras
News
Description
This repository serves as a Transfer Learning Suite. The goal is to easily be able to perform transfer learning using any built-in Keras image classification model! Any suggestions to improve this repository or any new features you would like to see are welcome!

Installation
This project has the following dependencies:
-
Numpy
sudo pip install numpy -
OpenCV Python
sudo apt-get install python-opencv -
TensorFlow
sudo pip install --upgrade tensorflow-gpu -
Keras
sudo pip install keras
Usage
The only thing you have to do to get started is set up the folders in the following structure:
โโโ "dataset_name"
| โโโ train
| | โโโ class_1_images
| | โโโ class_2_images
| | โโโ class_X_images
| | โโโ .....
| โโโ val
| | โโโ class_1_images
| | โโโ class_2_images
| | โโโ class_X_images
| | โโโ .....
| โโโ test
| | โโโ class_1_images
| | โโโ class_2_images
| | โโโ class_X_images
| | โโโ .....
Then you can simply run main.py! Check out the optional command line arguments:
usage: main.py [-h] [--num_epochs NUM_EPOCHS] [--mode MODE] [--image IMAGE]
[--continue_training CONTINUE_TRAINING] [--dataset DATASET]
[--resize_height RESIZE_HEIGHT] [--resize_width RESIZE_WIDTH]
[--batch_size BATCH_SIZE] [--dropout DROPOUT] [--h_flip H_FLIP]
[--v_flip V_FLIP] [--rotation ROTATION] [--zoom ZOOM]
[--shear SHEAR] [--model MODEL]
optional arguments:
-h, --help show this help message and exit
--num_epochs NUM_EPOCHS
Number of epochs to train for
--mode MODE Select "train", or "predict" mode. Note that for
prediction mode you have to specify an image to run
the model on.
--image IMAGE The image you want to predict on. Only valid in
"predict" mode.
--continue_training CONTINUE_TRAINING
Whether to continue training from a checkpoint
--dataset DATASET Dataset you are using.
--resize_height RESIZE_HEIGHT
Height of cropped input image to network
--resize_width RESIZE_WIDTH
Width of cropped input image to network
--batch_size BATCH_SIZE
Number of images in each batch
--dropout DROPOUT Dropout ratio
--h_flip H_FLIP Whether to randomly flip the image horizontally for
data augmentation
--v_flip V_FLIP Whether to randomly flip the image vertically for data
augmentation
--rotation ROTATION Whether to randomly rotate the image for data
augmentation
--zoom ZOOM Whether to randomly zoom in for data augmentation
--shear SHEAR Whether to randomly shear in for data augmentation
--model MODEL Your pre-trained classification model of choice
