Perhaps you should try some spelling variations:
"modified trained convolution algorithms" » "modified trained evolution algorithm", "modified trained solution algorithm", "modified trained convolutional algorithms", "modified traces convolution algorithms"
"modified df approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified adam approximation algorithms", "modified bi1 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 convolution algorithms") or ("modified df approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified trained convolution algorithms") OR ("modified df approximation algorithms")).
• Removing quotes may allow a broader search: (( modified trained convolution algorithms ) or ( modified df approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified trained convolution algorithms") or ("modified df approximation algorithms"))*.
