A preprocessing layer which buckets continuous features by ranges.
layer_discretization(
object,
bin_boundaries = NULL,
num_bins = NULL,
epsilon = 0.01,
...
)
What to call the new Layer
instance with. Typically a keras
Model
, another Layer
, or a tf.Tensor
/KerasTensor
. If object
is
missing, the Layer
instance is returned, otherwise, layer(object)
is
returned.
A list of bin boundaries. The leftmost and rightmost bins
will always extend to -Inf
and Inf
, so bin_boundaries = c(0., 1., 2.)
generates bins (-Inf, 0.)
, [0., 1.)
, [1., 2.)
, and [2., +Inf)
. If
this option is set, adapt
should not be called.
The integer number of bins to compute. If this option is set,
adapt
should be called to learn the bin boundaries.
Error tolerance, typically a small fraction close to zero (e.g. 0.01). Higher values of epsilon increase the quantile approximation, and hence result in more unequal buckets, but could improve performance and resource consumption.
standard layer arguments.
This layer will place each element of its input data into one of several contiguous ranges and output an integer index indicating which range each element was placed in.
Input shape:
Any tf.Tensor
or tf.RaggedTensor
of dimension 2 or higher.
Output shape: Same as input shape.
