Visualization of tensors - part 1

This video visualizes tensors. It shows some introduction to tensor theory and demonstrates it with the Cauchy stress tensor. Future parts of this series will show more theory and more examples. It talks about the term ’tensor’ as used in physics and math. In the field of AI the term ’tensor’ was borrowed with a simplified meaning. In AI it simply means a multi-dimensional array. So for example the array “double a[4][6]“ (4 by 6 matrix of doubles) is called a second-order tensor, but there’s no special relationship to vector spaces, as shown in the video.
