conffig(y, t) fh = conffig(y, t)
conffig(y, t)
displays the confusion matrix
and classification performance for the predictions mat{y}
compared with the targets t
. The data is assumed to be in a
1-of-N encoding, unless there is just one column, when it is assumed to
be a 2 class problem with a 0-1 encoding. Each row of y
and t
corresponds to a single example.
In the confusion matrix, the rows represent the true classes and the columns the predicted classes.
fh = conffig(y, t)
also returns the figure handle fh
which
can be used, for instance, to delete the figure when it is no longer needed.
