X-CNN: Cross-modal Convolutional Neural Networks for Sparse Datasets • /r/MachineLearning

This paper makes a small modification to a standard CNN architecture to improve results with small datasets. This shows a good improvement on CIFAR10/100 when trained with 40% of the data (usually 2-6%). I wish the authors shared their code though. They specifically mention using keras, so it's cant be more than a few hundred lines of python.
