Deep Learning and Reinforcement Learning

In this module, you will understand what is transfer learning and how it works. You will implement transfer learning in 5 general steps using a variety of popular pre-trained CNN architectures, such as VGG-16 and ResNet-50. You will study the differences among those CNN architectures and see how the invention of each solves the problem of its predecessors. Last, but not least, as we are moving to working with deeper neural networks, you will also be equipped with regularization techniques to prevent overfitting of complex models and networks.

In this module you become familiar with Recursive Neural Networks (RNNs) and Long-Short Term Memory Networks (LSTM), a type of RNN considered the breakthrough for speech to text recongintion. RNNs are frequently used in most AI applications today, and can also be used for supervised learning. 

In this module you become familiar with Autoencoders, an useful application of Deep Learning for Unsupervised Learning. Autoencoders are a neural network architecture that forces the learning of a lower dimensional representation of data, commonly images. In this module you will learn some Deep learning-based techniques for data representation, how autoencoders work, and to describe the use of trained autoencoders for image applications

In this module, you will learn about two types of generative models, which are Variational Autoencoders (VAEs) and Generative Adversarial Networks (GANs). We will look at the theory behind each model and then implement them in Keras for generating artificial images. The goal is usually to generate images that are as realistic as possible. In the last lesson of this module, we will touch on additional topics in deep learning, namely using Keras in a GPU environment for speeding up model training.

In this module you become familiar with other novel applications of Neural Networks. You will learn about Generative Adversarial Networks, frequently referred to as GANs, which are an application of Neural Networks to generate new data. Finally, you learn about Reinforcement Learning, one of the big promises for A.I., based on training algorithms by using rewards, instead of using a method to minimize error, which is what we have been using throughout the course.
