Algorithm 2 MDR (Similar with [31])

Procedure MDR $({\hat{u}}_{j | i}, r, l)$
For $r$ iterations do
For all caps $i$ in layer $l$ and caps $j$ in layer ( $l + 1)$ : $b_{i j} = \frac{1}{α} ⟨ o_{j | i}, s_{j} ⟩, c_{i j} = \frac{e x p^{(b_{i j})}}{\sum_{k} e x p^{(b_{i k})}}$
For all caps $j$ in layer ( $l + 1) :$ ${\hat{s}}_{j} = \sum c_{i j} o_{j | i}$ = , $s_{j} = {\hat{s}}_{j} / ||{\hat{s}}_{j}||$
For all caps $i$ in layer $l$ and caps j in layer $(l + 1) : w_{j} = \frac{||\sum c_{i j} o_{j | i}||}{1 + m a x_{k} | |\sum c_{i k} o_{k | i}|}$
Return $w_{j} s_{j}$
