WebExample of the confusion matrix . Wo = Woodland, G = Grassland, N = Non-vegetated, Wa = Water. Figure 2. The new structure called the “quality control column set” (QCCS), applied to the data from Figure 1. The locks symbolize that the marginals of the columns are fixed. For clarity, each column is presented in a different color ... WebConfusion matrix is not limited to binary classification and can be used in multi-class classifiers as well. The confusion matrices discussed above have only two conditions: positive and negative. For example, the table below summarizes communication of a whistled language between two speakers, zero values omitted for clarity. WebUse this stored procedure to calculate and to show different classification quality factors from a confusion matrix. Classification quality factors are, for example, the true positive rate for each predicted class, the false positive rate for each predicted class, the positive predictive value for each predicted class, the F-measure for each predicted class, … doco bank albany georgia
