Perhaps you should try some spelling variations:
noise processes » these processes (Expand search), like processes (Expand search), crime processes (Expand search)
decrease noise » decrease risk (Expand search)
method python » method method (Expand search), python python (Expand search)
action based » reaction based (Expand search), function based (Expand search)
decrease or » decrease of (Expand search), decrease on (Expand search), decrease in (Expand search)
or decrease » not decrease (Expand search), to decrease (Expand search), _ decrease (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 OR decrease noise processes ) OR ( action based method python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease or decrease noise processes ) OR ( action based method python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease or decrease noise processes ) OR ( action based method python programming ))*.
