FeatureVectorizer

A FeatureVectorizer puts one or more features into a single array.

The ordering of features in the output array is determined by inputList.

inputDimensions is a zero based index.

message FeatureVectorizer {
    message InputColumn {
        string inputColumn = 1;
        uint64 inputDimensions = 2;
    }

    repeated InputColumn inputList = 1;
}

FeatureVectorizer.InputColumn

message InputColumn {
    string inputColumn = 1;
    uint64 inputDimensions = 2;
}
