Predictive Analytics and Advanced Machine Learning in R and Azure
Use R and Azure ML Studio to build and tune advanced machine learning models.
Predictive analytics and machine learning techniques are revolutionizing business and government. Predictive Analytics and Machine Learning in R and Azure is aimed at the person who wants to have a better understanding of the mechanics behind the models and how these models are realistically applied in the business setting. In addition to covering advanced machine learning techniques in depth, the course covers the management of stakeholder expectations during predictive analytics projects and analytics project management. Advanced machine learning methods are discussed in depth, including those used to win global data science competitions.
This course is taught in R and Azure.
Who Should Attend?
This course is suited to any professional who already understands analytics and machine learning basics and is ready to progress to higher levels of sophistication. It is also suitable to any professional who is interested in who predictive analytics projects are conceptualised, scoped and project managed.
It is recommended that students have completed an introductory R programming course or MOOC and at least one 2nd year statistics unit at the university level.
