Perhaps you should try some spelling variations:
"learning-based data augmentation techniques" » "learning-based data segmentation techniques", "learning-based data imputation techniques", "learning-based image augmentation 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 data augmentation techniques") or ("learning-based code simulation technique"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("learning-based data augmentation techniques") OR ("learning-based code simulation technique"))*.
• Removing quotes may allow a broader search: (( learning-based data augmentation techniques ) or ( learning-based code simulation technique ))*.
