< heisenbuug> Hey, I wanted to perform some data pre-processing. This is the link I got which I think should have functions for data pre-processing: https://github.com/mlpack/mlpack/tree/master/src/mlpack/methods/preprocess
< heisenbuug> I also saw some past PRs to add Descriptive Statistics but I am not able to find the code for that...

< DavidFaragoGitte> rehi @zoq on Freenode: just a friendly reminder
< shrit[m]> Is there any way to print armadillo matrices in a nice way, like numpy, Only several starting and ending lines for example?
< rcurtin> shrit[m]: does using cout not work well? like cout << matrix or similar
< shrit[m]> When I use cout I can not see the difference between row and columns, all of them are streamed to output.
< rcurtin> I guess because there are too many columns and they wrap?
< shrit[m]> Actually there is about 10K rows and three columns
< rcurtin> oh, maybe print with .t()?
< rcurtin> but I'm not totally sure what you mean, maybe paste the output?
< shrit[m]> Exactly it is much easier to read when using transposing the matrix
< shrit[m]> @rcurtin, another question considering the meaning of the word ´coordinate´ in ensmallen. If I use ensmallen optimizer to train a neural network the word coordinate means the weights of the netowrk, am I right?
< rcurtin> shrit[m]: right, coordinate == weight of a network
< shrit[m]> Exactly, So If I want to store the best coordinate, I will have to use the callback ens::StoreBestCoordinate<> and then these coordinates are stored to a specific matrix, I want just to ask how to be sure that the Best coordinates are saved into the model.bin at the end?
< zoq> shrit[m]: Before saving, call model.Parameters() = bestParameter;
< shrit[m]> I will do a pull request and update an existing example, this one worth to be noted down, many thanks :+1

< rcurtin> I thought it's about time for another release, so I made a milestone and put in a few PRs that look pretty close:
< rcurtin> I didn't add any of the catch or WeightSize refactorings, since those aren't actually user visible (so if they get in, great, if not, it shouldn't matter for users)
< rcurtin> if anyone else has any PRs that are "just about" done and can be merged in the next couple of days, feel free to point them out or just add them to the milestone! :)
