Fully Convolutional Networks

  1. Convolutional neural network. From Wikipedia, the free encyclopedia. Convolutional networks were inspired by biological processes[4] in which the connectivity pattern between neurons is inspired by the organization of the animal visual cortex
  2. Fully convolutional indicates that the neural network is composed of convolutional layers without any fully-connected layers or MLP usually found at the end of the network
