reduction technique » reduction techniques, truncation technique
model reduction » model predictive
based sensor » gas sensor, based sers
based model » based code, based modeling, based anodes

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