Overview of this book

This Learning Path is your complete guide to quickly getting to grips with popular machine learning algorithms. You'll be introduced to the most widely used algorithms in supervised, unsupervised, and semi-supervised machine learning, and learn how to use them in the best possible manner. Ranging from Bayesian models to the MCMC algorithm to Hidden Markov models, this Learning Path will teach you how to extract features from your dataset and perform dimensionality reduction by making use of Python-based libraries. You'll bring the use of TensorFlow and Keras to build deep learning models, using concepts such as transfer learning, generative adversarial networks, and deep reinforcement learning. Next, you'll learn the advanced features of TensorFlow1.x, such as distributed TensorFlow with TF clusters, deploy production models with TensorFlow Serving. You'll implement different techniques related to object classification, object detection, image segmentation, and more. By the end of this Learning Path, you'll have obtained in-depth knowledge of TensorFlow, making you the go-to person for solving artificial intelligence problems This Learning Path includes content from the following Packt products: • Mastering Machine Learning Algorithms by Giuseppe Bonaccorso • Mastering TensorFlow 1.x by Armando Fandango • Deep Learning for Computer Vision by Rajalingappaa Shanmugamani

Summary


In this chapter, we learned how to debug the code for building and training models in TensorFlow. We learned that we can fetch the tensors as NumPy arrays using tf.Session.run(). We can also print the values of tensors by adding tf.Print() operations in the computation graph. We also learned how to raise errors when certain conditions fail to hold during execution with tf.Assert() and other tf.assert_* operations. We closed the chapter with an introduction to the TensorFlow debugger (tfdbg) for setting breakpoints and watching the values of tensors like we would do for debugging the code in the Python debugger (pdb) or the GNU debugger (gdb).

This chapter brings our journey to a new milestone. We do not expect that the journey ends here, but we believe that the journey just got started and you will further expand and apply the knowledge and skills gained in this book.

We are keenly looking forward to hearing your experiences, feedback, and suggestions.
