Developer Guide for Intel® Data Analytics Acceleration Library 2018 Update 2
In Intel® Data Analytics Acceleration Library (Intel® DAAL), a quality metric is a numerical characteristic or a set of connected numerical characteristics that represents the qualitative aspect of the result returned by an algorithm: a computed statistical estimate, model, or result of decision making.
A common set of quality metrics can be defined for some training and prediction algorithms.
A typical workflow with quality metric set is the following:
Quality metrics are optional. They are computed when the computation is explicitly requested.
