Martin opened the scoring with a deflected close-range finish in the eighth minute before heading the winner four minutes after the break, following Andre Wisdom's cross from the right. Barnsley substitute Tomaz Cywka halved the deficit after 62 minutes with a 25-yard strike against his former club.
"I've got mixed emotions," Wilson said. "I think the back end of the game was very positive from our point of view; the first part of the game, going two-nil down in the manner we did, was really disappointing.
"We can't allow a very good footballing side, as Derby are, time and space on the ball and we gave them too much. We allowed them to dictate the pattern and the pace of the game and that really hurt us.
"It was like 'After you, Claude' to a certain degree and losing the two goals in the manner we did was disappointing. They were soft goals from our perspective but at least we put a shift in in the second period of the game but again it's too late against a team with quality like that."
Wilson added: "We need a lot of work doing. We can't continue to keep saying 'We should've got something out of the game, we should've done this', I'm bored with it already, I've only had three games. Having the same old stuff to say all the time, I'm not prepared to do it.
"We have to move and move players around in January as best we can, whether we've got to let players go we'll have to wait and see but if it's for the better of the team then we're going to have to do it."
