[mlpack] GSoC 2014 : Introduction and Interests

[Anand Soni]

Hi Ryan,
I will definitely keep the code as flexible as possible considering possible future additions.

And regarding the new classifier, the algorithm is fixed i.e the back propagation algorithm. We can improve on the efficiency of implementation which I will keep in mind if I go for implementing it. I welcome any other queries from your side.

Thanks a lot.
Regards,
Anand

I would like to know if your code will be flexible enough to support
additional metrics that may be added in the future.  If it's not, that
is something to consider.

No, it does not; if you are interested in adding this, let's make sure
it is faster than competing implementations, either through careful
implementation, or by implementing a more efficient algorithm.
