In order to get the most out of this book, we recommend that readers have basic knowledge of deep learning and data analytics. It is also preferable for readers to have basic knowledge of MLP (multilayer perceptrons) or feed forward networks, recurrent neural networks, LSTM, word vector representations, and some level of debugging skills to interpret the errors from the error stack. As this book targets Java and the DL4J library, readers should also have sound knowledge of Java and DL4J. This book is not suitable for anyone who is new to programming or who doesn't have basic knowledge of deep learning.
