Tensorflow.js tf.transpose()函数
Tensorflow.js是谷歌开发的一个开源库,用于在浏览器或节点环境中运行机器学习模型和深度学习神经网络。
tf.transpose()函数用于对指定的二维输入张量执行常规矩阵转置操作。
句法:
tf.transpose (x)
参数:此函数接受一个参数,如下所示:
- x:要转置的指定输入张量。
返回值:它返回一个张量作为转置操作的输出。
示例 1:
Javascript
// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
// Initializing a tensor of matrix along with
// its dimension
const a = tf.tensor2d([2, 4, 6, 8], [2, 2]);
// Calling the .transpose() function over the
// above tensor as its parameter
a.transpose().print();
Javascript
// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
// Using some tensor of matrix along with its dimensions
// as the parameter for .transpose() functions
tf.tensor2d([1, 3, 5, 7, 9, 11], [2, 3]).transpose().print();
tf.tensor2d([1, 3, 5, 7, 9, 11], [3, 2]).transpose().print();
输出:
Tensor
[[2, 6],
[4, 8]]
示例 2:
Javascript
// Importing the tensorflow.js library
import * as tf from "@tensorflow/tfjs"
// Using some tensor of matrix along with its dimensions
// as the parameter for .transpose() functions
tf.tensor2d([1, 3, 5, 7, 9, 11], [2, 3]).transpose().print();
tf.tensor2d([1, 3, 5, 7, 9, 11], [3, 2]).transpose().print();
输出:
Tensor
[[1, 7 ],
[3, 9 ],
[5, 11]]
Tensor
[[1, 5, 9 ],
[3, 7, 11]]
