Seeing Is Believing - Visualizing Convolutional Neural Networks

Description:

Ever wondered what kind of filters convolutional neural networks learn? Ever wondered what they “see”?

Ever felt like you are working with a “black box” and had no idea what is going on within?

To understand your neural networks better, sometimes, you got to put yourself in its shoes and see what it sees. And visualizations help you do just that. Its power can be leveraged in understanding the features learned by your model and ultimately interpret the results. Not only will this help you build better models but it can also help you tailor your training data to better suit your use case.

In this workshop, various state-of-the-art visualization techniques used by deep learning practitioners around the world will be explored. A hands-on session will be conducted where you’ll learn the intuition behind them and to implement the topics outlined below.
