Perhaps you should try some spelling variations:
"learning-based a segmentation techniques" » "learning-based a augmentation techniques", "learning-based a imputation techniques", "learning-based 3d segmentation techniques", "learning-based shape segmentation techniques", "learning-based _ segmentation techniques", "learning-based k segmentation techniques", "learning-based n segmentation techniques"
"learning-based a inhalation technique" » "learning-based a floatation technique", "learning-based a implantation technique", "learning-based a imputation techniques", "learning-based _ inhalation technique", "learning-based _ inflation technique", "learning-based k inflation technique", "learning-based k inhalation technique", "learning-based n inhalation technique"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("learning-based a inhalation technique") OR ("learning-based a segmentation techniques"))~.
• Removing quotes may allow a broader search: (( learning-based a inhalation technique ) or ( learning-based a segmentation techniques ))~.
• Adding a wildcard symbol may retrieve word variants: (("learning-based a inhalation technique") or ("learning-based a segmentation techniques"))*.
