Hello, does anybody know how calculate the Accuracy
http://en.wikipedia.org/wiki/Accuracy_and_precision
with a confusion matrix like this:

Qt Code:
  1. 95 0 0 0 0 0 0 0 3 0
  2. 394 95 52 69 43 32 58 81 124 52
  3. 42 0 39 17 0 0 0 0 5 0
  4. 30 0 0 60 0 6 0 0 5 0
  5. 51 0 0 0 31 0 2 0 10 4
  6. 41 1 0 3 0 22 3 0 19 0
  7. 30 0 0 0 0 0 63 0 2 0
  8. 12 0 2 2 0 0 0 80 3 3
  9. 38 0 0 4 0 0 0 0 55 0
  10. 36 0 0 0 1 0 1 5 15 42

In particular is it possible from the confusion matrix. I'm not able to apply to the formula to this matrix.

thanks
