内容简介：The manifold assumption is wildly used in maching learning, based on which many mainifold-inspired methods are described, explicitly or Implicitly.

In this report, we provide some results of the autoencoder (AE) in deep learning and our current works as follows:

1) explicit geometric interpretation in contractive AE, denosing AE, and winner-take-all AE;

2) Implicit manifold assumption in sparse coding

3) Fast approximation for primal splitting algorithm with the manifold assumption.
