Container for information returned by RegressionFeatures.constructFeatures.
Container for information returned by RegressionFeatures.constructFeatures. Note that as is, this declaration will cause a compiler warning:
"The outer reference in this type test cannot be checked at run time."
This is a known issue and is a scala bug. See: - https://issues.scala-lang.org/browse/SI-4440 - http://stackoverflow.com/questions/16450008/typesafe-swing-events-the-outer-reference-in-this-type-test-cannot-be-checked-a
A solution that would remove the warning is to make the class not final. Not doing this just to remove a warning.

A threshold dictating how many missing features to allow before making the prediction fail. None means the threshold is ∞. If, when mapping featureFunctions over the input, the resulting sequence contains more than numMissingThreshold values that are empty Iterable values, then the Features.missingOk value returned by constructFeatures will be false; otherwise, it will be true.
Extract the features from the raw data by mapping featureFunctions over the input.
Extract the features from the raw data by mapping featureFunctions over the input. If numMissingThreshold is not None and the number of resulting empty Iterables exceeds the numMissingThreshold value, then the resulting Features.missingOk value is false; otherwise, it will be true. If Features.missingOk is false, then go back and check all feature functions for missing values and add findings to the Features.missing map. This Features.missing is a mapping from the feature specification to the list of variable names whose associated values are missing from the input.

A helper trait for sparse regression models with String keys. This trait exposes the constructFeatures method which applies the featureFunctions to the input data and keeps track of missing features.
