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

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