Perhaps you should try some spelling variations:
augmentation techniques » segmentation techniques, imputation techniques
simulation techniques » imputation techniques, mitigation techniques, segmentation techniques
shape augmentation » shape segmentation, image augmentation, data augmentation
vm simulation » via simulation, _ simulation, a simulation
based shape » based sphere
based vm » based _, based 3d, based co

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