The 26-year-old has averaged a caution in every other game since moving to St James' Park in 2010 and more recently picked up a red card in the Magpies' 1-1 draw with Sunderland last month.
"That sending-off hurt and it has been difficult to forget about it and move on," said Tiote.
"I know that I have picked up too many yellow cards and need to be a lot more careful. I don't need the manager to tell me that. I cannot change my style of play, but it will get better."
Tiote is currently serving a three-match domestic ban.
