Perhaps you should try some spelling variations:
"learning-based anode segmentation techniques" » "learning-based anode augmentation techniques", "learning-based anode imputation techniques", "learning-based 3d segmentation techniques", "learning-based shape segmentation techniques", "learning-based code segmentation techniques"
"learning-based two floatation technique" » "learning-based two inhalation technique", "learning-based two implantation technique", "learning-based two imputation techniques", "learning-based _ floatation technique", "learning-based tool floatation technique", "learning-based co 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 two floatation technique") OR ("learning-based anode segmentation techniques"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"learning-based two floatation technique\") OR (\"learning-based anode segmentation techniques\"))".
• Removing quotes may allow a broader search: (( learning-based two floatation technique ) OR ( learning-based anode segmentation techniques )).
• Adding a wildcard symbol may retrieve word variants: (("learning-based two floatation technique") OR ("learning-based anode segmentation techniques"))*.
