Perhaps you should try some spelling variations:
"learning-based code segmentation techniques" » "learning-based code augmentation techniques", "learning-based 3d segmentation techniques", "learning-based shape segmentation techniques", "learning-based anode segmentation techniques", "learning-based no2de segmentation techniques", "learning-based twode segmentation techniques", "learning-based _de segmentation techniques"
"learning-based co imputation techniques" » "learning-based co implantation technique", "learning-based co augmentation techniques", "learning-based co floatation technique", "learning-based co limitation techniques", "learning-based no2 imputation techniques", "learning-based two imputation techniques", "learning-based _ imputation techniques"

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