Perhaps you should try some spelling variations:
"machine learning convolution algorithms" » "machine learning evolution algorithm", "machine learning solution algorithm"
"modified adaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive quantization algorithm", "modified passive estimation algorithm"

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

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