Perhaps you should try some spelling variations:
"patterns recognition" » "pattern recognition", "maternal recognition"
"pathogen recognition" » "pattern recognition", "antigen recognition", "motion recognition"
"emotions recognition" » "emotion recognition", "motion recognition", "emotion cognition"
"action recognition" » "emotion recognition", "activity recognition"

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: (((("patterns recognition") OR ((("pathogen recognition") OR ("action recognition"))))) OR ("emotions recognition")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"patterns recognition\") or (((\"pathogen recognition\") OR (\"action recognition\"))))) or (\"emotions recognition\"))".
• Removing quotes may allow a broader search: (((( patterns recognition ) or ((( pathogen recognition ) OR ( action recognition ))))) or ( emotions recognition )).
• Adding a wildcard symbol may retrieve word variants: (((("patterns recognition") or ((("pathogen recognition") OR ("action recognition"))))) or ("emotions recognition"))*.
