results problem #379

Closed ir1979 closed 3 years ago

ir1979 commented 3 years ago

In the results files we have: FP+FN+TP+TN != TotalNumberOfRecords. Why?

lscheinkman commented 3 years ago

During the detection phase there is probationary period where no scoring is done. This probationary period is set at 750 points for data files larger than 5000 points or 15% of the total records for files shorter than 5000.

FP+FN+TP+TN = Total number of scored data points (excluding probationary period) Total_Count = Total number of data points in the dataset (including probationary period)

Please refer to NAB Whitepaper, Section 3.1 for more details.
