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

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 networks") OR ("neural model artificial neural network"))~.
• Removing quotes may allow a broader search: (( neuron real artificial neural networks ) or ( neural model artificial neural network ))~.
• Adding a wildcard symbol may retrieve word variants: (("neuron real artificial neural networks") or ("neural model artificial neural network"))*.
