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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified df approximation algorithms ) or ( modified trained convolutional algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified df approximation algorithms ) OR ( modified trained convolutional algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified df approximation algorithms ) or ( modified trained convolutional algorithms ))*.
