Machine Learning Essentials

Course Code

BD79

Duration

3 Days

Working knowledge of either R, Python or Apache Spark.
Programming background.
No previous machine learning knowledge is assumed.
This course introduces popular Machine Learning techniques.

For each machine learning concept, we first discuss the foundations, its applicability and limitations. Then we explain the implementation and use, and specific use cases. This is achieved through a combination of about 50% lecture, 50% lab work.

Please note that this course does not cover in-depth coverage of Math / Stats is behind Machine Learning.
This course is designed for Data Scientists and Software Engineers.

In this course, participants will:

  • Learn popular machine learning algorithms, their applicability and limitations
  • Practice the application of these methods in a machine learning environment
  • Learn practical use cases and limitations of algorithms
