Perhaps you should try some spelling variations:
augmentation techniques » segmentation techniques, imputation techniques
simulation techniques » imputation techniques, mitigation techniques, segmentation techniques
data augmentation » image augmentation
n simulation » _ simulation, a simulation, _ simulations
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 simulation techniques ) or ( learning-based data augmentation techniques ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( learning-based n simulation techniques ) OR ( learning-based data augmentation techniques )).
• Adding a wildcard symbol may retrieve word variants: (( learning-based n simulation techniques ) or ( learning-based data augmentation techniques ))*.
