چکیده
Despite the effectiveness of dynamic routing procedure recently proposed in (Sabour et al., 2017), we still lack a standard formalization of the heuristic and its implications. In this paper, we partially formulate the routing strategy proposed in Sabour et al. (2017) as an optimization problem that minimizes a combination of clustering-like loss and a KL regularization term between the current coupling distribution and its last states. We then introduce another simple routing approach, which enjoys few interesting properties. In an unsupervised perceptual grouping task, we show experimentally that our routing algorithm outperforms the dynamic routing method proposed in Sabour et al. (2017).

Let $R$ be a 2-torsion free semiprime ring with extended centroid $C$, $U$ the Utumi quotient ring of $R$ and $m,n>0$ are fixed integers. We show that if $R$ admits derivation $d$ such that $b[[d(x), x]_n,[y,d(y)]_m]=0$ for all $x,yin R$ where $0neq bin R$, then there exists a central idempotent element $e$ of $U$ such that $eU$ is commutative ring and $d$ induce a zero derivation on $(1-e)U$. ...
