Query: From CDF to PDF --- A Density Estimation Method for High Dimensional
  Data   CDF2PDF is a method of PDF estimation by approximating CDF. The original idea
of it was previously proposed in [1] called SIC. However, SIC requires
additional hyper-parameter tunning, and no algorithms for computing higher
order derivative from a trained NN are provided in [1]. CDF2PDF improves SIC by
avoiding the time-consuming hyper-parameter tuning part and enabling higher
order derivative computation to be done in polynomial time. Experiments of this
method for one-dimensional data shows promising results.
