11. A computer-readable medium having computer-executable instructions for causing a computer to perform a method comprising: receive a handwritten input from a user; perform a recognition operation on the handwritten input to produce an initial recognition result; perform a comparison of the initial recognition result with at least one explicit sample previously provided by the user using a Kullback-Leibler distance measure operation; and identify at least part of the initial recognition result as a possible incorrect recognition result if the comparison reveals that the at least part of the initial recognition result is not consistent with the at least one explicit sample.
