sparse autoencoder (deep learning)
This is exercising codes for the 2nd assignement from " ACL 2012 + NAACL 2013 Tutorial: Deep Learning for NLP (without Magic) " http://www.socher.org/index.php/DeepLearningTutorial/DeepLearningTutorial
Detailed instructions can also be checked here: http://deeplearning.stanford.edu/wiki/index.php/Exercise:Sparse_Autoencoder
The major function updated are:
computeNumericalGradient.m sparseAutoencoderCost.m
Final result can be seen from weights.jpeg
