商品簡介
You do not need to be a programmer to start. Chapter 6 is a gentle, self-contained introduction to NumPy, the tool professional AI engineers use every day. If you have never written code, read the theory first and treat the code blocks as a second, more concrete explanation of the same maths.Notation used throughout: capital bold letters such as A, W, X denote matrices; lower-case letters such as x, b denote vectors; and lower-case italic letters such as aᵢⱼ denote a single number (a scalar) inside a matrix. The symbol Aᵀ means the transpose of A, and A⁻ means its inverse.
