Perhaps you should try some spelling variations:
"element tracking algorithm" » "element tracking algorithms" (Expand Search), "element training algorithms" (Expand Search), "element making algorithm" (Expand Search), "movement tracking algorithm" (Expand Search), "sleep tracking algorithm" (Expand Search), "element strain algorithm" (Expand Search)
"element svm algorithm" » "element em algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "elements ppm algorithm" (Expand Search)
"element based algorithm" » "engagement based algorithm" (Expand Search)

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

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