To get the most out of this book

To get the most out of this book you need a basic understanding of TensorFlow or a similar framework such as PyTorch. Familiarity obtained through basic TensorFlow tutorials that are freely available in the web should suffice to get started on this book.

A basic knowledge of mathematics, including an understanding of n-dimensional tensors, matrix multiplication, and so on, will also prove invaluable throughout this book. Finally, you need an enthusiasm for learning about cutting edge machine learning that is setting the stage for modern NLP solutions.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. For example: “After running the pip install command, you should have Jupyter Notebook available in the Conda environment.”

A block of code is set as follows:

def layer(x, W, b):
    # Building the graph
    h = tf.nn.sigmoid(tf.matmul(x,W) + b) # Operation to perform
    return h

Any command-line input or output is written as follows:

<tf.Variable 'ref:0' shape=(3, 2) dtype=float32, numpy=
array([[-1., -9.],
       [ 3., 10.],
       [ 5., 11.]], dtype=float32)>

Bold: Indicates a new term or an important word. Words that you see on the screen (such as in menus or dialog boxes) also appear in the text like this , for example: “The feature that builds this computational graph automatically in TensorFlow is known as AutoGraph.”
