Perhaps you should try some spelling variations:
based preprocessing » based processing (Expand search), and preprocessing (Expand search), data preprocessing (Expand search)
during increased » during increasing (Expand search), producing increased (Expand search), favoring increased (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decrease based » decreased base (Expand search), decrease blood (Expand search)
increased the » increase the (Expand search), increases the (Expand search)
the decrease » and decrease (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

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

• Removing quotes may allow a broader search: (( decrease to decrease based preprocessing ) OR ( decrease during increased the decrease ))~.
