Parameters
- paragraphPosition
- Type: System Int32
A zero-based index that specifies the position of the paragraph of interest.
Return Value
Type: DoubleThe confusion threshold in the range 0.0 to 1.0.
| Exception | Condition |

| ObjectDisposedException | If this CogOCVMaxRunParams object has already been disposed. |
Each paragraph builds a confusion matrix when it is trained. This matrix has a number for every pair of keys in the paragraph's font alphabet that indicates how confusable two keys are. Values near 1.0 are very confusable (for example "5" and "S"), and values near zero are not confusable ("1" and "5").
The confusion threshold specifies the value below which other keys are not considered by OCVMax for confusion purposes. For example, if OCVMax is expecting to find a "5", it will also check other potentially confusing keys to see if they are also good matches. With a confusion threshold of 0.9, the keys for "S" and "6" might be " tried, but "1" would not. With a threshold of 0.4, many somewhat similar keys would be tried, such as "E" or "8". With a threshold of 0, all keys would be tried.
