Perhaps you should try some spelling variations:
"learning-based shape segmentation techniques" » "learning-based shape augmentation techniques", "learning-based shape imputation techniques", "learning-based series segmentation techniques", "learning-based sphere segmentation techniques"
"learning-based code floatation technique" » "learning-based code inhalation technique", "learning-based code implantation technique", "learning-based code imputation techniques", "learning-based anode floatation 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 shape segmentation techniques") OR ("learning-based code floatation technique"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"learning-based shape segmentation techniques\") OR (\"learning-based code floatation technique\"))*".
• Removing quotes may allow a broader search: (( learning-based shape segmentation techniques ) OR ( learning-based code floatation technique ))*.
