Perhaps you should try some spelling variations:
feature optimization » resource optimization (Expand Search), feature elimination (Expand Search), structure optimization (Expand Search)
basis optimization » based optimization (Expand Search), task optimization (Expand Search), acid optimization (Expand Search)
topic feature » omics feature (Expand Search), top5 features (Expand Search)
binary mask » binary image (Expand Search)
mask basis » mask based (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: (( binary topic feature optimization algorithm ) OR ( binary mask basis optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary topic feature optimization algorithm ) OR ( binary mask basis optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary topic feature optimization algorithm ) OR ( binary mask basis optimization algorithm ))*.
