What is Sparse Auto-Encoder and what are its probable applications in unsupervised feature learning?

Dear Dr Solankar,

this is a good question. A wonderful explanation can be found in Andrew Ng’s lecture notes (refer to page 12 of the following pdf file from Stanford University Computer Science Class).

https://web.stanford.edu/class/cs294a/sparseAutoencoder.pdf

Yours sincerely,

Rainer
