Book description

Explore predictive analytics using step-by-step tutorials and build models to make prediction in a jiffy with a few mouse clicks

  • Learn how to build predictive models using a browser such as IE

  • Explore different machine learning algorithms available

  • Without any prior knowledge and experience get started with predictive analytics with confidence

    • In Detail

    This book provides you with the skills necessary to get started with Azure Machine Learning to build predictive models as quickly as possible, in a very intuitive way, whether you are completely new to predictive analysis or an existing practitioner.

    The book starts by exploring ML Studio, the browser-based development environment, and explores the first step—data exploration and visualization. You will then build different predictive models using both supervised and unsupervised algorithms, including a simple recommender system. The focus then shifts to learning how to deploy a model to production and publishing it as an API.

    The book ends with a couple of case studies using all the concepts and skills you have learned throughout the book to solve real-world problems.
