Perhaps you should try some spelling variations:
"learning-based code segmentation techniques" » "learning-based code augmentation techniques", "learning-based code imputation techniques", "learning-based 3d segmentation techniques", "learning-based shape segmentation techniques", "learning-based anode segmentation techniques"
"learning-based no2 inhalation technique" » "learning-based no2 floatation technique", "learning-based no2 implantation technique", "learning-based no2 imputation techniques", "learning-based _ inhalation technique", "learning-based co inhalation technique", "learning-based n inhalation 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 code segmentation techniques") OR ("learning-based no2 inhalation technique"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"learning-based code segmentation techniques\") OR (\"learning-based no2 inhalation technique\"))".
• Removing quotes may allow a broader search: (( learning-based code segmentation techniques ) OR ( learning-based no2 inhalation technique )).
• Adding a wildcard symbol may retrieve word variants: (("learning-based code segmentation techniques") OR ("learning-based no2 inhalation technique"))*.
