Help debugging HTM.java for anomaly detection

Does the NAB perform any special “warm-up” (i.e. letting the SP run a bit before engaging the TM?)

No

@cogmission

Can someone help me by giving me the formula for at least the “reward_low_FP_rate” calculation - like tell me how I could calculate it for a single file and multiple files? My intention is to do this outside the NAB and try and see where the problem is…

Please see the NAB documentation as to how scores are calculated:

• Home · numenta/NAB Wiki · GitHub
• [1510.03336] Evaluating Real-time Anomaly Detection Algorithms - the Numenta Anomaly Benchmark

It’s straightforward to run a data file (or multiple) outside of NAB and output a CSV with the (raw) anomaly scores for each record, and then compare that to the CSV that results from running NAB.
