Certified Data Science Specialist (CDSS)

Our lives are flooded by large amount of information, but not all of them is useful data. Therefore, it is essential for us to learn how to apply data science to every aspect of our daily life from personal finances, reading, lifestyle to making business decisions. Leveraging on this data to make our life easier, or unlock new economic value for a business, is what you are going to learn in this course.

This course is a hands-on guided course for you to learn the concepts, tools, and techniques that you need to begin learning data science. We will cover the key topics from data science to big data, and the processes of gathering, cleaning and handling data. This course is well balanced between theory and practical, and key concepts are taught using case studies references. Upon completion, participants will be able to perform the basic data handling tasks, collect and analyze data, and present them using industry standard tools.

This workshop is intended for individuals who are interested in learning data science, or who want to begin their career as a data scientist.
