Perhaps you should try some spelling variations:
"neuron femoral artificial neural network" » "neuron model artificial neural network", "neuron femoral artificial neural networks", "neutron femoral artificial neural network", "neurons femoral artificial neural network", "neuro femoral artificial neural network"
"nerf real artificial neural network" » "nerf can artificial neural network", "nerf model artificial neural network", "nerf real artificial neural networks", "nrf real 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: (("neuron femoral artificial neural network") or ("nerf real artificial neural network"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("neuron femoral artificial neural network") OR ("nerf real artificial neural network"))*.
• Removing quotes may allow a broader search: (( neuron femoral artificial neural network ) or ( nerf real artificial neural network ))*.
