Predictive Analytics and Machine Learning for Business
Predictive analytics has revolutionised business across a range of industry verticals.
Predictive analytics has revolutionised business across a range of industry verticals, including banking, insurance, healthcare, retail, telecom, media and e-commerce. Despite the returns on predictive analytics being well documented, companies often proceed cautiously when presented with new predictive analytics initiatives. And with good reason – poorly built predictive models are costly and useless to the organisation. With a strong emphasis on the proven machine learning models used by leading companies such as Google, Walmart and AIG, this course provides a solid grounding in machine learning methods including classification, random forests and decision trees.
This course is taught in R and Azure.
Who Should Attend?
This course builds core skills for those who require a grounding in predictive analytics. Candidates who will benefit from the course include:
- Graduate hires who are on track toward a career in analytics or data science
- Managers and executives who wish to use data to predict business unknowns
- Candidates already working in analyst positions, including (but not limited to) positions involved with data analytics, digital and marketing analytics, customer and market analysis
- Any other business professional who would like to make decisions on the basis of data
It is recommended that students have completed Introduction to Data Science and Analytics, or have an undergraduate degree in statistics or mathematics.

- Understand how to calculate the ROA (return on analytics) for predictive analytics projects
- Recognise business opportunities where the investment in predictive analytics is justified in the context of project risk and expected benefits
- Understand how to manage predictive analytics project risk proactively whilst preventing time and cost overruns
