Perhaps you should try some spelling variations:
decrease mining » decrease during (Expand search), decrease owing (Expand search), decreases weaning (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), or decrease (Expand search)

mining based » training based (Expand search), sensing based (Expand search)
decrease by » decreased by (Expand search), decrease in (Expand search), decrease of (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: (( decrease by decrease toc decrease ) OR ( decrease NOT decrease mining based ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease by decrease toc decrease ) OR ( decrease not decrease mining based ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease by decrease toc decrease ) OR ( decrease not decrease mining based ))*.
