Sabbatical 2018 Week 1: Getting Started with Big Data
Coursera: Big Data Specialization
Happy Sabbatical to me and Lisa Young. Today begins my journey into the world of Big Data. I’m starting by taking two Coursera Specializations on big data. A Coursera Specialization is a series of courses that helps you master a skill. I’m beginning with the Big Data Specialization by UC San Diego. This specialization includes 6 courses. Description: “Do you need to understand big data and how it will impact your business? This Specialization is for you. You will gain an understanding of what insights big data can provide through hands-on experience with the tools and systems used by big data scientists and engineers. Previous programming experience is not required! You will be guided through the basics of using Hadoop with MapReduce, Spark, Pig and Hive. By following along with provided code, you will experience how one can perform predictive modeling and leverage graph analytics to model problems. This specialization will prepare you to ask the right questions about data, communicate effectively with data scientists, and do basic exploration of large, complex datasets. In the final Capstone Project, developed in partnership with data software company Splunk, you’ll apply the skills you learned to do basic analyses of big data.”
I was glad to discover this specialization on Coursera because it’s exactly what I need for my sabbatical, and the best part is it only cost $50 a month. I’m anticipating I can finish in 3-4 months. The series is designed to be a part time endeavor; however, I have lots of time to devote to the courses. UC San Diego is an academic powerhouse, recognized as one of the top 10 public universities by U.S. News and World Report, so I’m pleased to be learning from this elite group of instructors. The San Diego Supercomputer Center (SDSC) at UC San Diego is a leader in data-intensive computing and cyberinfrastructure.
The second specialization I plan to take is the Data Scientist Specialization by Johns Hopkins University which includes 10 courses. Description: “Ask the right questions, manipulate data sets, and create visualizations to communicate results. This Specialization covers the concepts and tools you’ll need throughout the entire data science pipeline, from asking the right kinds of questions to making inferences and publishing results.” I’m a bit apprehensive about this series, as they do recommend some programming experience (in any language). And they also suggest “a working knowledge of mathematics up to algebra.” Ugh! I’m not sure I have a working knowledge of mathematics. I guess we’ll see. I somehow managed four college degrees (AA, BA, MA, EDD) and only remember taking one math class (college Algebra) which I took way back in 1984. Lucky for me Coursera offers a course for people like me: Data Science Math Skills by Duke. It’s a 4 week course that is designed to teach learners the basic math you will need in order to be successful in almost any data science math course and was created for learners who have basic math skills but may not have taken algebra or pre-calculus. We’ll see how this goes. Wish me luck.
