Vanishing and Exploding Gradients – Lecture Notes
{Var}(w) \cdot \operatorname {Var}(x)\]
Since \(\operatorname {Var}(\mathcal{U}(-1,1))=1/3\) , we have in total \(n/3\) , and for \(\mathcal{N}(0,1)\) we get \(n\) and exploding gradients.

By \(\operatorname {Var}(\mathcal{U}(-\tfrac 1{\sqrt{n}},+\tfrac 1{\sqrt{n}}))=\frac1{3n}\) , we have a total of \(\frac13\) and vanishing gradient problems.
