Machine Learning Essentials with Python and Spark (TTML5506-K)

Course Objectives

This program provides a structured, engaging learning experience for students to progressively attain the technical skills they require to engage in meaningful machine learning projects and activities, right after the training ends. Working in a hands-on learning environment, led by our Machine Learning expert instructor, students will learn about and explore:

• Popular machine learning algorithms, their applicability, and limitations
• Practical application of these methods in the Spark machine learning environment
• Practical use cases and limitations of algorithms

Course Prerequisites

This course is geared for experienced, intermediate-skilled developers or others (with prior Python experience) intending to start using learning about and working with basic machine learning algorithms and concepts.  Attendees should be comfortable working with Python programming.  Students should also be able to navigate Linux command line, and who have basic knowledge of Linux editors (such as VI / nano) for editing code.

Pre-Requisites:  Students should have attended or have incoming skills equivalent to those in this course:

·        Strong basic Python Skills.  Attendees without Python background may view labs as follow along exercises or team with others to complete them. (NOTE: This course is also offered in R – please inquire for details)

·        Good foundational mathematics in Linear Algebra and Probability

·        Basic Linux skills, including familiarity with command-line options such as ls, cd, cp, and su
