Perhaps you should try some spelling variations:
imputation techniques » implantation technique, augmentation techniques, segmentation techniques
inflation technique » inhalation technique, implantation technique, mitigation techniques
n imputation » _ computation, _ reputation
k inflation » _ inflation
based n » based _, based no2, based 3d
based k » based _, based 3d, based co

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 n imputation techniques ) OR ( learning-based k inflation technique ))~.
• Adding a wildcard symbol may retrieve word variants: (( learning-based n imputation techniques ) or ( learning-based k inflation technique ))*.
