Geoffrey Hinton, the father of deep learning, created a huge stir in the space of deep learning by introducing a new network. This network was called the Capsule Network (CapsNet). An algorithm to train this network was also brought forth, which is called dynamic routing between capsules. For the first time, Hinton spoke about it in 2011 in the paper called transforming autoencoder. In 2017 November, a full paper was published by Hinton and his team regarding the Capsule network.
