Method Detail

withSize

public static DenseVectorFeatureType withSize(int size)

Returns a DenseVectorType for a vector of known fixed size.

Parameters:

size - The fixed vector size for features of this type. If a feature's type is DenseVectorFeatureType with size 100, then for all instances of this feature (in all examples/observations) the feature value will always be represented as an array of length 100.

withUnknownSize

public static DenseVectorFeatureType withUnknownSize()

Returns a DenseVectorType for a vector of unknown/dynamic size. If a feature's type is DenseVectorFeatureType with size UNKNOWN_SIZE, then instances of this feature in various examples/observations may have different sizes.

getSize

public int getSize()

Returns:

the size, which might be UNKNOWN_SIZE
