Machine Learning & Deep Learning Essentials with Spark and TensorFlow

Course Objectives

This “skills-centric” course is about 50% hands-on lab and 50% lecture, with extensive practical exercises designed to reinforce fundamental skills, concepts and best practices taught throughout the course.  Throughout the program, working in a hands-on learning environment guided by our expert instructor, students will

• Learn popular machine learning algorithms, their applicability, and limitations
• Practice the application of these methods in the Spark machine learning environment
• Learn practical use cases and limitations of algorithms
• Will explore not just the related APIs, but will also learn the theory behind them
• Work with real world datasets from Uber, Netflix, Walmart, Prosper, etc.

Need different skills or topics?  If your team requires different topics or tools, additional skills or custom approach, this course may be easily adjusted to accommodate.  We offer additional related Machine Learning, AI, Deep Learning, data science, programming (Python, R, Java, Scala etc.) and development courses which may be blended with this course for a track that best suits your learning objectives. Our team will collaborate with you to understand your needs and will target the course to focus on your specific learning objectives and goals.
