tf.histogram_fixed_width

TensorFlow 1 version View source on GitHub

Return histogram of values.

Given the tensor values, this operation returns a rank 1 histogram counting the number of entries in values that fell into every bin. The bins are equal width and determined by the arguments value_range and nbins.

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.
dtype dtype for returned histogram.
name A name for this operation (defaults to 'histogram_fixed_width').

A 1-D Tensor holding histogram of values.

TypeError If any unsupported dtype is provided.
tf.errors.InvalidArgumentError If value_range does not satisfy value_range[0] < value_range[1].

Examples:

# 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]
hist = tf.histogram_fixed_width(new_values, value_range, nbins=5)
hist.numpy()
array([2, 1, 1, 0, 2], dtype=int32)
