Neural networks and deep learning
Neural networks, and specifically deep learning, seem to have taken over the AI/ML world, at least if you focus only on what you see in the news. As you have learned in this class, there is a lot to AI! In this module, we will just scratch the surface of what a neural network is and how neural networks relate to deep learning.
Neural networks, specifically the fully-connected feed forward networks that we will study first in this module, have been around for multiple decades. The reason that you hear more about them recently has to do with the success of the deep learning and convolutional networks (CNNs). In the past 5 years or so, CNNs have shown up in the news given their great success at identifying a wide variety of images. They have found their way into a wide variety of applications, including your smart phone in ways you probably don’t even notice!
The ubiquitous application of ML for image recognition has also sparked a recognition that it can be misused as well. While we will not discuss that in this module, we will in the AI & ethics module coming up in a few weeks!
