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

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

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