Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...
A test data set is a data set that is independent of the training data set, but that follows the same probability distribution as the training data set. If a model fit to the training data set also fits the test data set well, minimal overfitting has taken place (see figure below). A better fitting of the training data set as opposed to the ...
Each Unicode code point is encoded either as one or two 16-bit code units.Code points less than 2 16 ("in the BMP") are encoded with a single 16-bit code unit equal to the numerical value of the code point, as in the older UCS-2.
Employment testing is the practice of administering written, oral, or other tests as a means of determining the suitability or desirability of a job applicant. The premise is that if scores on a test correlate with job performance , then it is economically useful for the employer to select employees based on scores from that test.

Label propagation is a semi-supervised algorithm in machine learning that assigns labels to previously unlabeled data points. At the start of the algorithm, a (generally small) subset of the data points have labels (or classifications).
A sample is a value of the signal at a point in time and/or space; this definition differs from the term's usage in statistics, which refers to a set of such values. [ A ] A sampler is a subsystem or operation that extracts samples from a continuous signal .
The original information may or may not appear literally in the encoded output; codes that include the unmodified input in the output are systematic, while those that do not are non-systematic. A simplistic example of ECC is to transmit each data bit three times, which is known as a (3,1) repetition code .
