weka / PrincipalComponents / 0.1.1

This is the PrincipalComponents filter, as implemented in Weka:

Send your input to the algorithm as a simple Json object, with the following parameters:

dataUrl: The path to the data to be manipulated (this path should point to the Data API)
options: A string that contains any options that you would like to specifically set for this filter (format: param name followed by desired value separated by space: e.g. "-C 5 -t 2"). For options specific to this filter, please see Weka docs linked above
writeUrl: (optional) Default behavior is to overwrite the dataUrl, if you specify this parameter, your filtered data will be written to this url. (caution: Specify writeUrl if you do not want your data to be overwritten with the filtered data!)
