Perhaps you should try some spelling variations:
"image 1_decoding algorithm" » "image modeling algorithm" (Expand Search), "image 1_developing algorithm" (Expand Search), "table 1_decoding algorithm" (Expand Search)
"data training algorithms" » "data learning algorithms" (Expand Search), "data learning algorithm" (Expand Search), "data tracking algorithms" (Expand Search), "data pertaining algorithms" (Expand Search), "data mining algorithms" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: (((("image 1_decoding algorithm") OR ("data training algorithms"))) OR ("element data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 1_decoding algorithm\") OR (\"data training algorithms\"))) OR (\"element data algorithm\"))".
• Removing quotes may allow a broader search: (((( image 1_decoding algorithm ) OR ( data training algorithms ))) OR ( element data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 1_decoding algorithm") OR ("data training algorithms"))) OR ("element data algorithm"))*.
