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

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