Introduction to TensorFlow
Learn to build, train and run deep neural networks using TensorFlow
In the first part of this course, you will learn the fundamentals of TensorFlow, such as computational graphs, autodifferentiation, sessions, placeholders and more. You will then learn how to apply this knowledge by building a simple logistic regression classifier, training it using stochastic gradient descent, and running it to make predictions. In the process you will also get a brief introduction (or reminder) to some of the fundamental concepts of Machine Learning, such as training sets/test sets, overfitting, cost function and gradient descent. In the second part of this course, you will learn about deep neural networks and techniques to train them efficiently using TensorFlow.
Google open sourced TensorFlow in November 2015, and since then it has grown into the most popular Deep Learning framework available today. Many companies are already using it to tackle complex tasks such as Natural Language Processing, image or speech recognition and much more, often gaining a decisive competitive advantage: don’t get left behind!
Join expert Aurélien Géron for a handson, indepth exploration of TensorFlow. In this course, you’ll learn how to use TensorFlow to build, train and run stateoftheart Deep Learning systems.
What you'll learnand how you can apply it
 How TensorFlow relies on computation graphs, and how they are used.
 Stochastic Gradient Descent to optimize a cost function, using Automatic Differentiation to compute the gradients.
 How neural networks are built and how they can perform tasks such as image classification.
And you will be able to:
 Use TensorFlow for any kind of numerical computation.
 Build, train and run Deep Neural Networks.
 Train Convolutional Neural Networks to perform image classification.
This training course is for you because...
You are a Software Engineer, Data Scientist, or Data Analyst with little or no Machine Learning experience and need to learn how to use TensorFlow to build, train and run deep neural networks for image recognition, natural language processing or more.
Prerequisites
Basic experience with the Python programming language.
Materials needed in advance/downloads:
A Jupyter server with all of the notebooks will be provided. Browserbased, with no installations required.
Alternatively, if you would like to run things locally, you will need a working Python 3.4+ installation with TensorFlow 0.12.0, NumPy and Jupyter.
Recommended Preparation:
Getting started with TensorFlow (lesson)
Introduction to Python (video)
Analyzing Data with Python (webcast)
About your instructor

Aurélien Géron is a Machine Learning consultant, author of the O’Reilly book “Handson Machine Learning with ScikitLearn and TensorFlow”. A former Googler, he led the YouTube video classification team from 2013 to 2016. He was also a founder and CTO of Wifirst from 2002 to 2012, a leading Wireless ISP in France, and a founder and CTO of Polyconseil in 2001, the firm that now manages the electric car sharing service Autolib. Before this he worked as a software engineer in a variety of domains: finance (JP Morgan and Société Générale), defense (Canada's DOD), and healthcare (blood transfusion).
