Perhaps you should try some spelling variations:
"neural model artificial neural networks" » "neural femoral artificial neural networks", "neural real artificial neural networks", "nerf model artificial neural networks", "normal model artificial neural networks"
"neuron model artificial neural network" » "neuron femoral artificial neural network", "neuron real artificial neural network", "nerf model 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: (("neural model artificial neural networks") or ("neuron model artificial neural network"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("neural model artificial neural networks") OR ("neuron model artificial neural network")).
• Removing quotes may allow a broader search: (( neural model artificial neural networks ) or ( neuron model artificial neural network )).
• Adding a wildcard symbol may retrieve word variants: (("neural model artificial neural networks") or ("neuron model artificial neural network"))*.
