Perhaps you should try some spelling variations:
"neural model artificial neural network" » "neural femoral artificial neural network", "neural real artificial neural network", "neural model artificial neural networks", "neuron model artificial neural network", "nerf model artificial neural network", "normal model artificial neural network"
"neuronal can artificial neural network" » "neuronal real artificial neural network", "neuronal _ artificial neural network", "neuronal can 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: (("neuronal can artificial neural network") or ("neural model artificial neural network"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("neuronal can artificial neural network") OR ("neural model artificial neural network")).
• Removing quotes may allow a broader search: (( neuronal can artificial neural network ) or ( neural model artificial neural network )).
• Adding a wildcard symbol may retrieve word variants: (("neuronal can artificial neural network") or ("neural model artificial neural network"))*.
