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