Perhaps you should try some spelling variations:
"learning-based nnode segmentation techniques" » "learning-based nnode augmentation techniques", "learning-based nnode imputation techniques", "learning-based 3d segmentation techniques", "learning-based shape segmentation techniques", "learning-based anode segmentation techniques", "learning-based anodes segmentation techniques", "learning-based code segmentation techniques"
"learning-based k simulation technique" » "learning-based k imputation techniques", "learning-based k inhalation technique", "learning-based k implantation technique", "learning-based _ simulation technique", "learning-based a simulation technique", "learning-based _ simulations technique", "learning-based n simulation technique", "learning-based 3d simulation technique"

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 k simulation technique") or ("learning-based nnode segmentation techniques"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("learning-based k simulation technique") OR ("learning-based nnode segmentation techniques"))*.
• Removing quotes may allow a broader search: (( learning-based k simulation technique ) or ( learning-based nnode segmentation techniques ))*.
