HistogramFixedWidth
#include <math_ops.h>
Return histogram of values.
Summary
Given the tensor
values
, this operation returns a rank 1 histogram counting the number of entries in
values
that fall into every bin. The bins are equal width and determined by the arguments
value_range
and
nbins
.
# Bins will be: (-inf, 1), [1, 2), [2, 3), [3, 4), [4, inf)
nbins = 5
value_range = [0.0, 5.0]
new_values = [-1.0, 0.0, 1.5, 2.0, 5.0, 15]
with tf.get_default_session() as sess:
hist = tf.histogram_fixed_width(new_values, value_range, nbins=5)
variables.global_variables_initializer().run()
sess.run(hist) => [2, 1, 1, 0, 2]
Args:
-
scope: A
Scope
object
-
values: Numeric
Tensor
.
-
value_range: Shape [2]
Tensor
of same
dtype
as
values
. values <= value_range[0] will be mapped to hist[0], values >= value_range[1] will be mapped to hist[-1].
-
nbins: Scalar
int32
Tensor
. Number of histogram bins.
