out-of-band

(redirected from OOB data)

out-of-band

(communications)
The exchange of call control information on a dedicated channel, separate from that used by the telephone call or data transmission.

Sometimes used to describe what communications people call "shift characters", such as the ESC that leads control sequences for many terminals, or the level shift indicators in the old 5-bit Baudot codes.

out-of-band

(3)
In personal communication, using methods other than electronic mail, such as telephone or snail-mail.

out-of-band

(software)
Values returned by a function that are not in its "natural" range of return values, but rather signal some kind of exception. Many C functions that normally return a non-negative integer return -1 to indicate failure.

This use confuses "out-of-band" with "out-of-range". It is actually a clear example of in-band signalling since it uses the same "channel" for control and data.

Compare hidden flag, green bytes, fence.

(1) Separate from the primary frequency or system. See signaling in/out-of-band and out-of-band data.

(2) Not at the regular time. See out-of-band patch.

where [x.sub.i] is a sample in the OOB data and [C.sub.i] is the class label of the sample [x.sub.i].
The former is defined as the average decrease between the percentage of votes for the correct class in the untouched OOB data and the percentage of votes for the correct class in the variable permuted OOB data averaged over all trees.
The data that are not collected are called OOB data. The fitness function of a given mtry value and OOB error is constructed, the AFSA is used to find the optimal mtry value, and the QC model is constructed with the optimal mtry value.
Therefore, the RF model is applied to the OOB data. The deviations between predicted and reference values are then used to calculate the OOB error, which is the mean square error (MSE) for the regression.
