The gradient is closely related to the total derivative (total differential) : they are transpose (dual) to each other. Using the convention that vectors in are represented by column vectors, and that covectors (linear maps ) are represented by row vectors, the gradient and the derivative are expressed as a column and row vector, respectively, with the same components, but transpose of each other: design your own backyard online

We then see how PyTorch and Tensorflow can compute gradient for us. 4. Gradient For a function $${\displaystyle f(x,y,z)}$$ in three-dimensional Cartesian coordinate variables, the gradient is the vector field: As the name implies, the gradient is proportional to and points in the direction of the function's most rapid (positive) change.
