Perhaps you should try some spelling variations:
"machines learning convolution algorithm" » "machines learning convolution algorithms", "machines learning evolution algorithm", "machines learning solution algorithm", "machine learning convolution algorithm", "active learning convolution algorithm", "mapping learning convolution 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: (("machines learning convolution algorithm") or ("modified notion approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines learning convolution algorithm") OR ("modified notion approximation algorithms"))*.
• Removing quotes may allow a broader search: (( machines learning convolution algorithm ) or ( modified notion approximation algorithms ))*.
