Perhaps you should try some spelling variations:
"learning-based cross segmentation techniques" » "learning-based cross augmentation techniques", "learning-based cross imputation techniques", "learning-based series segmentation techniques", "learning-based roms segmentation techniques", "learning-based access segmentation techniques", "learning-based closed segmentation techniques"
"learning-based code simulation technique" » "learning-based code imputation techniques", "learning-based code inhalation technique", "learning-based code implantation technique", "learning-based 3d simulation technique", "learning-based based simulation technique", "learning-based carlo simulation technique", "learning-based anode 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 code simulation technique") or ("learning-based cross segmentation techniques"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("learning-based code simulation technique") OR ("learning-based cross segmentation techniques"))*.
• Removing quotes may allow a broader search: (( learning-based code simulation technique ) or ( learning-based cross segmentation techniques ))*.
