Message ClassificationResult

class rst.classification.ClassificationResult

A class representing the result of a classification process.

An example of such a result could be the output of an SVM-based classifier.

In the simplest form, only the name of a decided class is given. However, it is also possible to give the whole vector of possible classes with their probabilities.

Code author: Johannes Wienke <jwienke@techfak.uni-bielefeld.de>

decided_class

Type :OCTET-VECTOR

A shortcut to get the most likely class easily.

This needs to be an ASCII string.

classes

Type :array of rst.classification.ClassificationResult.ClassWithProbability

The complete vector of classes with their probabilities if suitable.

The results in this vector should of cause not contradict decided_class.

Message ClassWithProbability

class rst.classification.ClassificationResult.ClassWithProbability

TODO

name

Type :OCTET-VECTOR

Name of the class (ASCII string).

confidence

Type :FLOAT32

Unit: TODO

Some kind of confidence, values are application dependent.

However, values summing up to 1 are preferred.
