Perhaps you should try some spelling variations:
"modified trained convolutional algorithm" » "modified trained convolution algorithms", "modified trained evolution algorithm", "modified trained evolutionary algorithm", "modified graph convolutional algorithm", "modified traces convolutional algorithm"
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"

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

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