tf.math.reduce_euclidean_norm
Computes the Euclidean norm of elements across dimensions of a tensor.
tf.math.reduce_euclidean_norm(
input_tensor, axis=None, keepdims=False, name=None
)
Reduces input_tensor along the dimensions given in axis. Unless keepdims is true, the rank of the tensor is reduced by 1 for each entry in axis. If keepdims is true, the reduced dimensions are retained with length 1.
If axis is None, all dimensions are reduced, and a tensor with a single element is returned.
For example:
x = tf.constant([[1, 2, 3], [1, 1, 1]]) # x.dtype is tf.int32
tf.math.reduce_euclidean_norm(x) # returns 4 as dtype is tf.int32
y = tf.constant([[1, 2, 3], [1, 1, 1]], dtype = tf.float32)
tf.math.reduce_euclidean_norm(y) # returns 4.1231055 which is sqrt(17)
tf.math.reduce_euclidean_norm(y, 0) # [sqrt(2), sqrt(5), sqrt(10)]
tf.math.reduce_euclidean_norm(y, 1) # [sqrt(14), sqrt(3)]
tf.math.reduce_euclidean_norm(y, 1, keepdims=True) # [[sqrt(14)], [sqrt(3)]]
tf.math.reduce_euclidean_norm(y, [0, 1]) # sqrt(17)
| Args | |
|---|---|
input_tensor |
The tensor to reduce. Should have numeric type. |
axis |
The dimensions to reduce. If None (the default), reduces all dimensions. Must be in the range [-rank(input_tensor), rank(input_tensor)). |
keepdims |
If true, retains reduced dimensions with length 1. |
name |
A name for the operation (optional). |
| Returns | |
|---|---|
| The reduced tensor, of the same dtype as the input_tensor. |
