Perhaps you should try some spelling variations:
"learning-based two segmentation techniques" » "learning-based two imputation techniques", "learning-based 3d segmentation techniques", "learning-based tool segmentation techniques", "learning-based co segmentation techniques"
"learning-based two augmentation techniques" » "learning-based two imputation techniques", "learning-based data augmentation techniques", "learning-based tool augmentation techniques", "learning-based co augmentation techniques"

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 two segmentation techniques") OR ("learning-based two augmentation techniques"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"learning-based two segmentation techniques\") OR (\"learning-based two augmentation techniques\"))*".
• Removing quotes may allow a broader search: (( learning-based two segmentation techniques ) OR ( learning-based two augmentation techniques ))*.
