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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("neuron model artificial neural network") or ("nerf model artificial neural networks"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("neuron model artificial neural network") OR ("nerf model artificial neural networks"))*.
• Removing quotes may allow a broader search: (( neuron model artificial neural network ) or ( nerf model artificial neural networks ))*.
