A Tour of Convolutional Networks Guided by Linear Interpreters

ICCV 2019poster

Convolutional networks are large linear systems divided into layers and connected by non-linear units. These units are the "articulations" that allow the network to adapt to the input. To understand how a network manages to solve a problem we must look at the articulated decisions in entirety. If we…
