The auto-encoder is used for dimensional reduction, and as a tool for unsupervised feature learning. Further, auto-encoder has been used for building and training multi-layer neural networks.

When we talk about auto-encoders, we introduced a sparsity and I what to know what is the purpose of introducing an sparsity term for auto-encoders.
