The similar effect has been observed in "Dynamic Routing between Capsules" by Hinton et al.: https://arxiv.org/pdf/1710.09829.pdf . The "squashing" function in their paper (Section 2) is used for discriminating entity existence, while in our paper (Equation 6) it is leveraged to amplify reachability.
