Used in mathematics, physics, and computing to refer to a function that defines a distance between elements of a set, or more generally a standard of measurement.
from German Metrik
In this space, we use Euclidean distance as the metric.
We need to define a new metric for this space.
We defined metrics to evaluate the software's performance.
We applied the Euclidean metric to the dataset.
We computed a metric to evaluate the model's performance.
Borrowed from German 'Metrik', ultimately from Latin 'metricus' and Greek 'metrikos' (relating to measurement).
