| Daniel@0 | 24 </h2> |
| Daniel@0 | 25 <CODE>[C, rate] = confmat(y, t)</CODE> computes the confusion matrix <CODE>C</CODE> |
| Daniel@0 | 26 and classification performance <CODE>rate</CODE> for the predictions mat{y} |
| Daniel@0 | 27 compared with the targets <CODE>t</CODE>. The data is assumed to be in a |
| Daniel@0 | 28 1-of-N encoding, unless there is just one column, when it is assumed to |
| Daniel@0 | 29 be a 2 class problem with a 0-1 encoding. Each row of <CODE>y</CODE> and <CODE>t</CODE> |
| Daniel@0 | 30 corresponds to a single example. |
| Daniel@0 | 31 |
| Daniel@0 | 32 <p>In the confusion matrix, the rows represent the true classes and the |
| Daniel@0 | 33 columns the predicted classes. The vector <CODE>rate</CODE> has two entries: |
| Daniel@0 | 34 the percentage of correct classifications and the total number of |
| Daniel@0 | 35 correct classifications. |
