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