Introduction to TensorFlow 2.0
Learn the basics of machine learning and deep learning using TensorFlow 2.0
TensorFlow is a popular, opensource, machine learning software developed by Google’s Brain Team. TensorFlow boasts a collection of visualization tools and can run on multiple GPUs, CPUs, and mobile operating systems. This workshop will introduce participants to core concepts in machine learning and TensorFlow, with a focus on neural networks. Topics include building and launching graphs in TensorFlow, evaluating model performance, and managing overfitting. Students will also gain a deep understanding of how neural networks work, including more complex architectures such as convolutional neural networks and recurrent neural networks. During the course, students will engage in exercises that develop their ability to apply these concepts to build models suitable for classification and regression tasks using structured and unstructured data, such as tables, text, images, and timeseries data as well as data of mixed structure and type.
What you'll learnand how you can apply it
By the end of this live, handson, online course, you’ll understand:
 What machine learning, neural networks, deep learning, and artificial intelligence are.
 What TensorFlow is and what applications it is good for.
 How to build predictive models using a mix of structured and unstructured data sets.
 Where neural network architecture has been extended for more complex modeling.
And you’ll be able to:
 Create statistical models for classification and regression using TensorFlow.
 Evaluate the benefits and disadvantages of using TensorFlow over other machine learning software.
 Document, save, share, and recreate models using TensorFlow’s Keras API.
 Design model architectures that combine data sources and types for predictions in complex contexts.
