Jun 2, 2015 at 15:12 comment added KalEl As long as the model learned in the full representation of the data, the reduced 2-dimensional view is simply a view - visualizing what happened. In other cases though, often where you have high dimensional feature-space, you do apply your models on the reduced space - there you do change the problem to a 'new' one. This is frequently done in text mining to reduce the term-document-matrix before any model is fitted.
Jun 2, 2015 at 15:06 comment added Ruthger Righart Thank you very much for this thorough answer! I read about using PCA to do this. I wonder if the obtained hyperplane with the resulting two components reliably represents the one of the original dimensions, or if it is simply a new data problem that one creates by reducing dimensions. Any ideas on this?
