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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 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 ))*.
