  Learning from small amounts of labeled data is a challenge in the area of
deep learning. This is currently addressed by Transfer Learning where one
learns the small data set as a transfer task from a larger source dataset.
Transfer Learning can deliver higher accuracy if the hyperparameters and source
dataset are chosen well. One of the important parameters is the learning rate
for the layers of the neural network. We show through experiments on the
ImageNet22k and Oxford Flowers datasets that improvements in accuracy in range
of 127% can be obtained by proper choice of learning rates. We also show that
the images/label parameter for a dataset can potentially be used to determine
optimal learning rates for the layers to get the best overall accuracy. We
additionally validate this method on a sample of real-world image
classification tasks from a public visual recognition API.
