Perhaps you should try some spelling variations:
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
decreasing costs » decreasing cost (Expand search), decreasing rest (Expand search), decrease costs (Expand search)
at preprocessing » data preprocessing (Expand search), and preprocessing (Expand search), by preprocessing (Expand search)
costs decrease » loss decrease (Expand search), cells decrease (Expand search), cost increase (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease on (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decreasing costs decrease at preprocessing ) OR ( decrease NOT decrease response decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decreasing costs decrease at preprocessing ) OR ( decrease not decrease response decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreasing costs decrease at preprocessing ) OR ( decrease not decrease response decrease ))*.
