Perhaps some comments are in order regarding the classification rate. Many of the textures in the Brodatz album are not homogeneous. Webmisclassification as a test selection metric. For each possible test, the partitions of the training data made by that test are found. For each partition, the class that minimizes misclassification costs is found, and the cost of the errors of the partition is computed. The test that minimizes the sum of the costs of all partitions is selected.

WebUse Average Cell Values. For each cell in each half of the matrix, the two values (upper- and lower-triangular) are averaged and the average replaces both values. For example, if the cost of misclassifying A as B is 1 and the cost of misclassifying B as A is 3, then this control replaces both of those values with the average (1+3)/2 = 2. WebJan 24, 2024 · Here, it can be noticed that for the same misclassification probabilities, the 15-component mixture has to be simulated from much smaller average overlap values than the 5-component setting.
