Introduction The element-wise operations have been discussed in the last postÂ Maths in a Neural Network: Element-wise. This post will focus on how to represent all the equations found in the previous post in vectors. 1 Feed-forward Let's consider a 2-3-2 network. 1.1 Element-wise operations $latex a^{(l)}_p = f^{(l)}(z^{(l)}_p)\quad (1)&s=2$ $latex z^{(l)}_p = \sum_q w^{(l)}_{(qp)} a^{(l-1)}_q … Continue reading Maths in a Neural Network: Vectorization
