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