Encoding(value)Defines how a feature is encoded. Defaults to IDENTITY.

input = [27, 6.0, 150]
index_feature_mapping = ["age", "height", "weight"]
BAG_OF_FEATURES_SPARSE (3):
The tensor represents a bag of features where each index
maps to a feature. Zero values in the tensor indicates
feature being non-existent.

index_feature_mapping = ["a", "b", "c", "d", "e"]
INDICATOR (4):
The tensor is a list of binaries representing whether a
feature exists or not (1 indicates existence).

COMBINED_EMBEDDING (5):
The tensor is encoded into a 1-dimensional array represented
by an encoded tensor.

Select this encoding when the input tensor is encoded into a
2-dimensional array represented by an encoded tensor.
