Perhaps you should try some spelling variations:
"learning-based anodes segmentation techniques" » "learning-based anodes augmentation techniques", "learning-based anodes imputation techniques", "learning-based series segmentation techniques", "learning-based anode segmentation techniques", "learning-based code segmentation techniques"
"learning-based two reduction techniques" » "learning-based two reduction technique", "learning-based two imputation techniques", "learning-based h2o2 reduction techniques", "learning-based _ reduction techniques", "learning-based tool reduction techniques", "learning-based co reduction 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 two reduction techniques") or ("learning-based anodes segmentation techniques"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("learning-based two reduction techniques") OR ("learning-based anodes segmentation techniques"))*.
• Removing quotes may allow a broader search: (( learning-based two reduction techniques ) or ( learning-based anodes segmentation techniques ))*.
