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