Overview of this book

Getting to grips with tensors, deep learning, and neural networks can be intimidating and confusing for anyone, no matter their experience level. The breadth of information out there, often written at a very high level and aimed at advanced practitioners, can make getting started even more challenging. If this sounds familiar to you, The TensorFlow Workshop is here to help. Combining clear explanations, realistic examples, and plenty of hands-on practice, it’ll quickly get you up and running. You’ll start off with the basics – learning how to load data into TensorFlow, perform tensor operations, and utilize common optimizers and activation functions. As you progress, you’ll experiment with different TensorFlow development tools, including TensorBoard, TensorFlow Hub, and Google Colab, before moving on to solve regression and classification problems with sequential models. Building on this solid foundation, you’ll learn how to tune models and work with different types of neural network, getting hands-on with real-world deep learning applications such as text encoding, temperature forecasting, image augmentation, and audio processing. By the end of this deep learning book, you’ll have the skills, knowledge, and confidence to tackle your own ambitious deep learning projects with TensorFlow.

3. TensorFlow Development

Activity 3.01: Using TensorBoard to Visualize Tensor Transformations

Solution:

  1. Import the TensorFlow library and set a seed:
    import tensorflow as tf
    tf.random.set_seed(42)
  2. Set the log directory and initialize a file writer object to write the trace:
    logdir = 'logs/'
    writer = tf.summary.create_file_writer(logdir)
  3. Create a TensorFlow function to multiply two tensors and add a value of 1 to all elements in the resulting tensor using the ones_like function to create a tensor of the same shape as the result of the matrix multiplication. Then, apply a sigmoid function to each value of the tensor:
    @tf.function
    def my_func(x, y):
        r1 = tf.matmul(x, y)
        r2 = r1 + tf.ones_like(r1)
        r3 = tf.keras.activations.sigmoid(r2)
        return r3
  4. Create two tensors with the shape 5x5x5:
    x = tf.random.uniform((5, 5, 5))
    y = tf.random.uniform((5, 5, 5))
  5. Turn...
