Perhaps you should try some spelling variations:
simulation techniques » mitigation techniques, segmentation techniques, inhalation technique
imputation techniques » implantation technique, augmentation techniques, segmentation techniques
co imputation » co limitation
k simulation » _ simulation, a simulation, _ simulations
based co » based code, based no2, based two
based k » based _, based n, based 3d

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