Perhaps you should try some spelling variations:
"normal model artificial neural network" » "normal femoral artificial neural network", "normal real artificial neural network", "neural model artificial neural network", "novel model artificial neural network"
"normal model artificial neural networks" » "normal femoral artificial neural networks", "normal real artificial neural networks", "neural model artificial neural networks", "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 ("normal model artificial neural networks"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"normal model artificial neural network\") OR (\"normal model artificial neural networks\"))".
• Removing quotes may allow a broader search: (( normal model artificial neural network ) OR ( normal model artificial neural networks )).
• Adding a wildcard symbol may retrieve word variants: (("normal model artificial neural network") OR ("normal model artificial neural networks"))*.
