Good day,

I have a few assumptions about ram-hours, which I would be grateful if someone could confirm or refute.

1) If I am running moa without sizeofag.jar, then ram-hours will output negative values, which means ram-hours are not being measured.
2) Ram-hours are given in GBs, therefore if I want them on MBs all I have to do is multiply then by 1024.
3) Assuming 1 and 2 are true, then the following table would be correct. Columns 1 to 3 are original outputs, column 4 represents RAM-Hours (GB) * 1024.

learning
evaluation
instances
evaluation time
(cpu seconds)
RAM-Hours (GB) RAM-Hours (MB) classifications
correct (percent)
1000 229.357725 0.01 12.81 92.8
2000 510.4135304 0.05 50.21 86.5
3000 776.8969442 0.09 91.13 92.9
4000 1120.754443 0.15 157.28 95.2
5000 1458.588633 0.23 237.33 90.9
6000 1845.948178 0.33 333.29 90.2
7000 2259.964169 0.46 469.58 92
8000 2683.237874 0.61 625.60 97.6
9000 3090.976826 0.77 785.96 97.1
9324 3429.94257 0.90 922.67 96.1

4) Regarding experiment presented on the table above, it is reasonable to state: "model cost was 922.67 MB"

Best Regards,
Heitor

Hi Heitor,

1/ That's correct, if there is no sizeofag.jar present, the Ram-hours measures are negative
2/ Ram-hours are given in Gb/Hour
3/ Yes, if you have z Gb/Hour, you have 1024z Mb/Hour
4/ model cost was 922.67 MB/Hour

Cheers, Albert

Hi Sir,

Please would you mind telling me if it is Gbytes/hour or Gbits/hour?

Kind Regards
