Perhaps you should try some spelling variations:
convolutional algorithms » convolution algorithms, evolution algorithm, evolutionary algorithm
approximation algorithm » approximation algorithms
trained convolutional » graph convolutional
time approximation » one approximation, _ approximation
modified trained » modified traces
modified time » modified bi1, modified male

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified trained convolutional algorithms ) OR ( modified time approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified trained convolutional algorithms ) or ( modified time approximation algorithm ))*.
