Perhaps you should try some spelling variations:
"data learning algorithm" » "data learning algorithms" (Expand Search), "meta learning algorithm" (Expand Search), "deep learning algorithm" (Expand Search), "a learning algorithm" (Expand Search)
"element custom algorithm" » "element fusion algorithm" (Expand Search), "element control algorithm" (Expand Search), "element lasso algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element custom algorithm") OR ("element method algorithm"))) OR ("data learning algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element custom algorithm\") OR (\"element method algorithm\"))) OR (\"data learning algorithm\"))".
• Removing quotes may allow a broader search: (((( element custom algorithm ) OR ( element method algorithm ))) OR ( data learning algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element custom algorithm") OR ("element method algorithm"))) OR ("data learning algorithm"))*.
