mindspore.mint.nn.functional.normalize

mindspore.mint.nn.functional.normalize(input, p=2.0, dim=1, eps=1e-12)[source]

Perform normalization of inputs over specified dimension

For a tensor input of sizes $(n_{0}, . . ., n_{d i m}, . . ., n_{k})$ , each $n_{d i m}$ -element vector v along dimension dim is transformed as

v = \frac{v}{max ({‖ v ‖}_{p}, \in)}

With the default arguments it uses the Euclidean norm over vectors along dimension 1 for normalization.

Warning

This is an experimental API that is subject to change or deletion.

Parameters

input (Tensor) – input tensor of any shape.
p (float) – the exponent value in the norm formulation. default: 2.
dim (int) – the dimension to reduce. default: 1.
eps (float) – small value to avoid division by zero. default: 1e-12.

Returns

Tensor, shape and data type are the same as input.

>>> import numpy as np
>>> from mindspore import Tensor, mint
>>> tensor = Tensor(np.array([[0, 1, 2], [3, 4, 5], [6, 7, 8]]), mindspore.float32)
>>> output = mint.nn.functional.normalize(tensor)
