#include <math_ops.h>
Renvoie l'histogramme des valeurs.
Résumé
Compte tenu des values
du tenseur, cette opération renvoie un histogramme de rang 1 comptant le nombre d'entrées dans values
qui tombent dans chaque bac. Les bacs ont la même largeur et sont déterminés par les arguments value_range
et 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]
Arguments :
- scope : un objet Scope
- valeurs :
Tensor
numérique . - value_range: Shape [2]
Tensor
du même dtype
que values
. les valeurs <= value_range[0] seront mappées à hist[0], les valeurs >= value_range[1] seront mappées à hist[-1]. - nbins :
int32 Tensor
. Nombre de compartiments d'histogramme.
