Evaluate Performance.
a On the Summary Statistics worksheet, review the Separation Statistics
table.
Correct splits should be as high as possible with missed and additional
splits as low as possible.
b
Review the Accuracy and Classification Rate statistics for the Per-
Document Results in the Classification Statistics table.
It is likely that Accuracy is close to 100% but Classification Rate is much
lower.
c
Review the Confusion Matrix.
Ideally only the blue shaded cells will contain numbers. If there are any
numbers in the other (unshaded) cells, examples of the document type on
the left have been classified as the type in the column.
5
Improve accuracy.
If your accuracy is less than 90% or your confusion matrix has a lot of data in
the unshaded cells, refer to the following book of the INDICIUS Help for
information on how to troubleshoot and improve performance:
How to configure | Recognition | Step 4: Test | Page Classification and
Separation | Step 5: Evaluate and Improve Performance.
6 If your accuracy Summary is at least 90%, but your classification rate
Summary is lower than 80%, determine your confidence thresholds by
modifying the Confidence Threshold values and recalculating the statistics.
