Recurrent Neural Networks
In chapter 4, we learned about Convolutional Neural Networks (CNNs), and saw how they exploit the spatial geometry of their inputs. For example, CNNs for images apply convolutions to initially small patches of the image, and progress to larger and larger areas of the image using pooling operations. Convolutions and pooling operations for images are in two dimensions: the width and height. For audio and text streams, one-dimensional convolution and pooling operations are applied along the time dimension, and for video streams, these operations are applied in three dimensions: along the height, width, and time dimensions.
In this chapter, we will focus on Recurrent Neural Networks (RNNs), a class of neural networks ...
