[mlpack-git] [mlpack] [Proposal]Add a function to visualize the results of sparse_autoencoder (#452)

[stereomatchingkiss]

If the users can see the result of encoder matrix, they will be easier to debug, I would like to write a function to visualize result of training.

1 : I suggest an api as following(base on shark)

template<typename InputType>
exportFiltersToPGMGrid(std::string const &fileName, arma::Mat<InputType> const &input, 
size_t width, size_t height);

Is this api good enough?

2 : which module it should belongs to?
ann?
method/sparseAutoencoder?
mlpack::data?
or others?

3 : do mlpack have any function to do the bilinear interpolation?

Thank you
