ConfusionMatrix Object (IConfusionMatrix Interface)

ConfusionMatrix object (IConfusionMatrix interface) in the ABBYY FineReader Engine API — the confusion matrix for a classification model, showing how objects from each category were classified.

This object represents the confusion matrix for a classification model. The confusion matrix is a square table in which each cell contains the number of objects classified into category <column-name> while belonging to category <row-name>. The diagonal cells will contain the number of correctly assigned elements for each category.

The matrix size is the number of categories plus one, with the last column showing the number of objects in each category for which classification failed.
