Class FeatureValueDomain (1.7.1)

FeatureValueDomain(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Domain details of the input feature value. Provides numeric information about the feature, such as its range (min, max). If the feature has been pre-processed, for example with z-scoring, then it provides information about how to recover the original feature. For example, if the input feature is an image and it has been pre-processed to obtain 0-mean and stddev = 1 values, then original_mean, and original_stddev refer to the mean and stddev of the original feature (e.g. image tensor) from which input feature (with mean = 0 and stddev = 1) was obtained.

Attributes

NameDescription
min_value float
The minimum permissible value for this feature.
max_value float
The maximum permissible value for this feature.
original_mean float
If this input feature has been normalized to a mean value of 0, the original_mean specifies the mean value of the domain prior to normalization.
original_stddev float
If this input feature has been normalized to a standard deviation of 1.0, the original_stddev specifies the standard deviation of the domain prior to normalization.
