Heuristics that use all examples and/or class labels

[nkraemer]

Right now, a heuristic only uses the information from one particular example (e.g. a single image). For the implementation of dimensionality reduction heuristics (as e.g. Principal Component Analysis or Partial Least Squares), we need to access all examples and possible the class labels. Is it possible to extend the MASH platform accordingly?

New optional methods will be added to the heuristic API for that kind of usage in a later version.
