Introduction to Convolutional Neural Networks

Tensors are essential in CNN. The input, intermediate representation, and parameters in a CNN are all tensors. Tensors with order higher than 3 are also widely used in a CNN. For example, we will soon see that the convolution kernels in a convolution layer …

An Introduction to Tensors for Students of Physics and ...

an attempt to record those early notions concerning tensors. It is intended to serve as a bridge from the point where most undergraduate students “leave off” in their studies of mathematics to the place where most texts on tensor analysis begin. A basic knowledge of vectors, matrices, and

Chapter 3 Cartesian Tensors - DAMTP

Cartesian Tensors 3.1 Suffix Notation and the Summation Convention We will consider vectors in 3D, though the notation we shall introduce applies (mostly) just as well to n dimensions. For a general vector x = (x 1,x 2,x 3) we shall refer to x i, the ith component of x. The index i may take any of the values 1, 2 or 3, and we refer to “the ...

Strain Tensors F. characterizes changes of relative placements during motion . but is not a suitable measure of deformation for engineering purposes: It is not null when no changes of distances and angles take place, e.g., in rigid-body motions. Strain. is a normalized measure of deformation which . characterizes the
