Perhaps you should try some spelling variations:
simulation techniques » imputation techniques, mitigation techniques, segmentation techniques
reduction techniques » reduction technique, imputation techniques
3d simulation » _ simulation, a simulation, mri simulation
n reduction » _ reduction, _ prediction, _ production
based 3d » based _, based co, based k
based n » based _, based k, based no2

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( learning-based n reduction techniques ) OR ( learning-based 3d simulation techniques ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( learning-based n reduction techniques ) OR ( learning-based 3d simulation techniques ))".
• Adding a wildcard symbol may retrieve word variants: (( learning-based n reduction techniques ) OR ( learning-based 3d simulation techniques ))*.
