Key Features Build deep learning models with transfer learning
principles in Python implement transfer learning to solve
real-world research problems Perform complex operations such as
image captioning neural style transfer Book DescriptionTransfer
learning is a machine learning (ML) technique where knowledge
gained during training a set of problems can be used to solve other
similar problems. The purpose of this book is two-fold; firstly, we
focus on detailed coverage of deep learning (DL) and transfer
learning, comparing and contrasting the two with easy-to-follow
concepts and examples. The second area of focus is real-world
examples and research problems using TensorFlow, Keras, and the
Python ecosystem with hands-on examples. The book starts with the
key essential concepts of ML and DL, followed by depiction and
coverage of important DL architectures such as convolutional neural
networks (CNNs), deep neural networks (DNNs), recurrent neural
networks (RNNs), long short-term memory (LSTM), and capsule
networks. Our focus then shifts to transfer learning concepts, such
as model freezing, fine-tuning, pre-trained models including VGG,
inception, ResNet, and how these systems perform better than DL
models with practical examples. In the concluding chapters, we will
focus on a multitude of real-world case studies and problems
associated with areas such as computer vision, audio analysis and
natural language processing (NLP). By the end of this book, you
will be able to implement both DL and transfer learning principles
in your own systems. What you will learn Set up your own DL
environment with graphics processing unit (GPU) and Cloud support
