A common use case is, you don't have enough data to train a good model like ResNet50. +What you can do is utilize pre-trained model from Gluon, tweak the model according to your neeed, fine-tune the model on your small dataset, and deploy the model to integrate with your service. + +We will use the [Oxford 102 Category Flower Dateset](http://www.robots.ox.ac.uk/~vgg/data/flowers/102/) as an example to show you the steps. + +## Prepare training data + +You can use this [script](https://github.com/Arsey/keras-transfer-learning-for-oxford102/blob/master/bootstrap.py) to download and organize your data into train, test, and validation sets. Simply run: +```python +python bootstrap.py +``` + +Now your data will be organized into the following format, all the images belong to the same category will be put together +``` +data +├── train +│ ├── 0 +│ │ ├── image_06736.jpg +│ │ ├── image_06741.jpg +... +│ ├── 1 +│ │ ├── image_06755.jpg +│ │ ├── image_06899.jpg +... +├── test +│ ├── 0 +│ │ ├── image_00731.jpg +│ │ ├── image_0002.jpg +... +│ ├── 1 +│ │ ├── image_00036.jpg +│ │ ├── image_05011.jpg + +``` + + +# Training using Gluon +### Define Hyper-paramerters +Now let's first import neccesarry packages: +```python +import mxnet as mx +import numpy as np +import os, time Review comment: please reorganise the imports to follow PEP8 convention ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
