Question 1: Short answer

mediumAI-checkedNeural Network Basics

A one-hidden-layer ReLU network maps a scalar input xx to a scalar output through 4 hidden units, f(x)=∑j=14vj ReLU(wjx+bj)+cf(x) = \sum_{j=1}^{4} v_j\,\mathrm{ReLU}(w_j x + b_j) + c. At most how many linear pieces can ff have on the real line?
