If you are a software developer who wants to build scalable AI-powered algorithms, you need to understand how to use the tools to build them. This Specialization will teach you best practices for using TensorFlow, a popular open-source framework for machine learning. In these courses you will:

  • Learn how to build machine learning models in TensorFlow
  • Build image recognition algorithms with deep neural networks and convolutional neural networks
  • Understand how to deploy your models on mobile and the web
  • Go beyond image recognition into object detection, text recognition, and more
  • Expand the basic APIs for custom learning/training

The Machine Learning course and Deep Learning Specialization teach the most important and foundational principles of Machine Learning and Deep Learning. This new deeplearning.ai TensorFlow Specialization teaches you how to use TensorFlow to implement those principles so that you can start building and applying scalable models to real-world problems. To develop a deeper understanding of how neural networks work, we recommend that you take the Deep Learning Specialization. The full deeplearning.ai TensorFlow Specialization will be available in July 2019, but you can get started with the first three courses on Coursera.
