Understanding the role of individual units in a deep neural network
2020
Proceedings of the National Academy of Sciences of the United States of America
Preserved Fulltext
Other Versions
In this work, we present network dissection, an analytic framework to systematically identify the semantics of individual hidden units within image classification and image generation networks. ...
First, we analyze a convolutional neural network (CNN) trained on scene classification and discover units that match a diverse set of object concepts. ...
To develop an improved understanding of how a network works, we have presented a way to analyze the roles of individual network units. ...
