COURSE OVERVIEW

Organizations use their data for decision support and to build data-intensive products and services, such as recommendation, prediction, and diagnostic systems. The collection of skills required by organizations to support these functions has been grouped under the term Data Science. This course will attempt to articulate the expected output of Data Scientists and then teach students how to use PySpark (part of Apache Spark) to deliver against these expectations. The course assignments include Log Mining, Textual Entity Recognition, and Collaborative Filtering exercises that teach students how to manipulate datasets using parallel processing with PySpark.

PREREQUISITES

This course covers advanced undergraduate-level material. It requires a programming background and experience with Python (or the ability to learn it quickly). All exercises will use PySpark (part of Apache Spark), but previous experience with Spark or distributed computing is NOT required. You should take this Python mini-quiz before the course and take this Python mini-course if you need to learn Python or refresh your Python knowledge.

Course Grading Policy

The components of the course grade are:

    • 8% Course software setup
    • 12% Quizzes in the lectures (scroll down below some of the videos for multiple choice and check box quizzes)
    • 80% Four lab exercises

The course is graded on the following scale:

    • 75-100: A grade
    • 55-74: B grade
    • Below 50: non-passing grade

The course software setup assignment is due June 6, 2015 at 00:00 UTC. Each week's lab exercise will be due the following Friday at 00:00 UTC. We encourage you to start software setup and each exercise as early as possible. There is an automatic 3-day grace period for submission deadlines. After the grace period, there is a 20% penalty for late submissions.
