ConfusionMatrix

Fields
annotationSpecs[] object (AnnotationSpecRef)

AnnotationSpecs used in the confusion matrix.

For AutoML Text Extraction, a special negative AnnotationSpec with empty id and displayName of "NULL" will be added as the last element.

rows[] array (ListValue format)

rows in the confusion matrix. The number of rows is equal to the size of annotationSpecs. rows[i][j] is the number of DataItems that have ground truth of the annotationSpecs[i] and are predicted as annotationSpecs[j] by the Model being evaluated.

For Text Extraction, when annotationSpecs[i] is the last element in annotationSpecs, i.e. the special negative AnnotationSpec, rows[i][j] is the number of predicted entities of annoatationSpec[j] that are not labeled as any of the ground truth AnnotationSpec. When annotationSpecs[j] is the special negative AnnotationSpec, rows[i][j] is the number of entities have ground truth of annotationSpec[i] that are not predicted as an entity by the Model. The value of the last cell, i.e. row[i][j] where i == j and annotationSpec[i] is the special negative AnnotationSpec, is always 0.
