I have .mat file where each training example is a 20*20 grayscale image of the digit. How to import this file into rapidminer and perform classification?
Matlab is not supported.
but would it not be possible to use some R script, e.g with the R.matlab package to import them into R and then export the files as a data table in some way?
or is this not possible, as it would have to be imported as some formatted file (binary, csv..) into Rapidminer first? Or could I import it just as it is as a .mat file and use the R script on it?
Of course you could also write your own operator for it. I am sure there are libaries around
