Quality Metrics for Binary Classification Algorithms

For two classes
C
1
and
C
2
, given a vector
X
= (
x
1
, …,
x
n
) of class labels computed at the prediction stage of the classification algorithm and a vector
Y
= (
y
1
, …,
y
n
) of expected class labels, the problem is to evaluate the classifier by computing the confusion matrix and connected quality metrics: precision, recall, and so on.
QualityMetricsId
for binary classification is
confusionMatrix
.
For description of the default quality metrics for binary classification, refer to Details .

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
