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

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

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