tensorflow.math.igamma()TensorFlow是谷歌设计的开源Python库,用于开发机器学习模型和深度学习神经网络。
igamma()
用于计算下限正则化的不完全伽马函数P(a, x)。P(a, x)定义为:。
")
其中gamma(a, x)是下位不完全gamma函数,定义为:。
")
语法:
tensorflow.math.igamma( x, y, name)
参数:
返回:
它返回一个dtype为x的张量。
示例 1:
# importing the library
import tensorflow as tf
# Initializing the input tensor
a = tf.constant([7, 8, 13, 11], dtype = tf.float64)
b = tf.constant([2, 8, 14, 5], dtype = tf.float64)
# Printing the input tensor
print('a: ', a)
print('b: ', b)
# Calculating the result
res = tf.math.igamma(a, b)
# Printing the result
print('Result: ', res)
输出:
a: tf.Tensor([ 7. 8. 13. 11.], shape=(4, ), dtype=float64)
b: tf.Tensor([ 2. 8. 14. 5.], shape=(4, ), dtype=float64)
Result: tf.Tensor([0.00453381 0.54703919 0.64154158 0.01369527], shape=(4, ), dtype=float64)
示例 2:
# Importing the library
import tensorflow as tf
# Initializing the input tensor
a = tf.constant([2, 8, 14, 5], dtype = tf.float32)
b = tf.constant([7, 8, 13, 11], dtype = tf.float32)
# Printing the input tensor
print('a: ', a)
print('b: ', b)
# Calculating the result
res = tf.math.igamma(a, b)
# Printing the result
print('Result: ', res)
输出:
a: tf.Tensor([ 2. 8. 14. 5.], shape=(4, ), dtype=float32)
b: tf.Tensor([ 7. 8. 13. 11.], shape=(4, ), dtype=float32)
Result: tf.Tensor([0.9927049 0.5470391 0.42695415 0.9848954 ], shape=(4, ), dtype=float32)
