Perhaps you should try some spelling variations:
imputation techniques » implantation technique, augmentation techniques, segmentation techniques
inflation technique » inhalation technique, implantation technique, mitigation techniques
co imputation » co limitation
n inflation » _ inflation, k inflation, law inflation
based co » based code, based no2, based two
based n » based _, based k, based no2

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( learning-based co imputation techniques ) OR ( learning-based n inflation technique ))~.
• Adding a wildcard symbol may retrieve word variants: (( learning-based co imputation techniques ) or ( learning-based n inflation technique ))*.
