Perhaps you should try some spelling variations:
segmentation techniques » augmentation techniques, imputation techniques
simulation techniques » imputation techniques, mitigation techniques, inhalation technique
k segmentation » 3d segmentation
a simulation » _ simulation
based a » based _, based n, based 3d
based k » based _, based n, based 3d

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 a simulation techniques ) or ( learning-based k segmentation techniques ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( learning-based a simulation techniques ) OR ( learning-based k segmentation techniques )).
• Adding a wildcard symbol may retrieve word variants: (( learning-based a simulation techniques ) or ( learning-based k segmentation techniques ))*.
