Tensor( tensor )
“ tensor ” The word was originally used by William · Ron · Hamilton is in 1846 In introducing . Yes , It's the Hamilton who invented quaternion :
-
Tensor It's actually a multidimensional array (multidimensional array)
-
Tensor The goal is to be able to create a higher dimensional matrix 、 vector .
An example of color
Color image file (RGB) It's usually handled as 3-d tensor, Every 2d array Medium element Represents a pixel ,R representative Red,G representative Green,B representative Blue
Multidimensional arrays
Draw a cube in three dimensions :
Higher dimensional tensors :
Initialize a vector
0 dimension
tf.tensor(1).print();
1 dimension
tf.tensor([1, 2, 3, 4]).print();
// or
tf.tensor1d([1, 2, 3]).print();
2 dimension
tf.tensor([[1, 2], [3, 4]]).print();
// or
tf.tensor2d([[1, 2], [3, 4]]).print();
3 dimension
tf.tensor([[[1], [2]], [[3], [4]]]).print();
// or
tf.tensor3d([[[1], [2]], [[3], [4]]]).print();
4 dimension
tf.tensor([[[[1], [2]], [[3], [4]]]]).print();
// or
tf.tensor4d([[[[1], [2]], [[3], [4]]]]).print();
5 dimension
tf.tensor([[[[[1], [2]], [[3], [4]]]]]).print();
// or
tf.tensor5d([[[[[1], [2]], [[3], [4]]]]]).print();
6 dimension
tf.tensor([[[[[[1],[2]],[[3],[4]]],[[[5],[6]],[[7],[8]]]]]]).print();
// or
tf.tensor6d([[[[[[1],[2]],[[3],[4]]],[[[5],[6]],[[7],[8]]]]]]).print();
