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 regression model capable of doing not only linear regression but polynomial regression in general.
This is useful because these conversions allow implicit conversion function from some of the AnyVal types and Options of AnyVal types to Iterable[(String, Double)]. This is useful because specifying features in the JSON spec like:
{ ... "features": { "intercept": "-3", "income": "${user.profile.income}" } }into sequences like:
