tensoreflusso:: ops:: Istogramma a larghezza fissa
#include <math_ops.h>
Restituisce l'istogramma dei valori.
Riepilogo
Dati i values
del tensore, questa operazione restituisce un istogramma di rango 1 che conta il numero di voci nei values
che rientrano in ogni contenitore. I contenitori hanno la stessa larghezza e sono determinati dagli argomenti value_range
e 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]
Argomenti:
- scope: un oggetto Scope
- valori:
Tensor
Numerico . - value_range: Forma [2]
Tensor
dello stesso dtype
dei values
. i valori <= value_range[0] verranno mappati su hist[0], i valori >= value_range[1] verranno mappati su hist[-1]. - nbins:
int32 Tensor
. Numero di contenitori dell'istogramma.
