Perhaps you should try some spelling variations:
"normal model artificial neural network" » "normal femoral artificial neural network", "normal real artificial neural network", "normal model artificial neural networks", "neural model artificial neural network"
"novel model artificial neural network" » "novel femoral artificial neural network", "novel real artificial neural network", "novel model artificial neural networks"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("normal model artificial neural network") OR ("novel model artificial neural network"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"normal model artificial neural network\") OR (\"novel model artificial neural network\"))".
• Removing quotes may allow a broader search: (( normal model artificial neural network ) OR ( novel model artificial neural network )).
• Adding a wildcard symbol may retrieve word variants: (("normal model artificial neural network") OR ("novel model artificial neural network"))*.
