Perhaps you should try some spelling variations:
"nerf model artificial neural network" » "nerf femoral artificial neural network", "new model artificial neural network", "neural model artificial neural network", "neuron 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"

Try widening your search to All Fields.

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