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

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 real artificial neural network\") OR (\"nerf model artificial neural network\"))~".
• Removing quotes may allow a broader search: (( neural real artificial neural network ) OR ( nerf model artificial neural network ))~.
• Adding a wildcard symbol may retrieve word variants: (("neural real artificial neural network") OR ("nerf model artificial neural network"))*.
