Digit Recognition Challenge

Solution to the Kaggle digit recognition challenge : www.kaggle.com/c/digit-recognizer/data

Main idea - create new examples by shifting source dataset and then randomly rotate all new examples

My code

• mxnet_lenet_submiision1.R is used to build the submission file. Note: Best score : 0.995

R Libraries

• MxNet http://mxnet.io (for convolutional neural networks)
• EBImage https://bioconductor.org/packages/release/bioc/html/EBImage.html

To go further

• Optimize convolutional network structure and tune parameters
• Using new techniques to creating new examples: degradation, some affine transformations
