New York Times Big Data 2013

If you follow data science news, you will know that the New York Times puts out some very good content. Well, recently they ran a section called BIG DATA 2013. There are many articles and tons of information. Happy Reading!

A Big Data Infographic

This infographic explains the Three V’s of big data, contains a nice list of analytical techniques, related trends and some other information.

Open Source Alternatives to AWS

Working with big data can often mean doing some cloud computing. If a public cloud like Amazon AWS is not an option, there are some open source alternatives. They all offer some level of compatibility with the AWS API for both EC2(compute) and S3(storage).

  1. Rackspace OpenStack
  2. Apache CloudStack
  3. Eucalyptus
  4. OpenNubula

Free Book on Big Data

Jason and Jeremy Kolb of Applied Data Labs recently released a new book, Secrets of the Big Data Revolution. As of today, it is free on Amazon. I have just started it, and it is good so far. It is only free for a limited time.

Big Data: Book Review

Not too long ago, I was in an airport looking for a book to help pass the time. I was thrilled to find a book with Big Data in the title, so I took it and started reading.


Big Data: A Revolution That Will Transform How We Live, Work, and Think

The book is titled, Big Data: A Revolution That Will Transform How We Live, Work, and Think. The authors are Viktor Mayer-Schonberger, professor at Oxford, and Kenneth Cukier, data editor at the Economist.

The book is well-written and entertaining. I would like to specifically point out 2 chapters that really stuck out to me. Chapter 4 on correlation provided an excellent description of why correlation is not the same as causation. It then went on to state that with all the data available, correlation might be all that is needed. Here is a quote from Chapter 4.

The correlations show what, not why, but as we have seen, knowing what is often good enough.

The final chapter, Chapter 10, is about what is next with big data. It provides a look into the future of where big data will make a difference: global problems, medicine, climate change, physics, sensors, and nearly all other parts of our lives. It also mentions that big data is only going to get bigger.

Also, chapter 5 introduced me to a new word, datafication. I am still not exactly sure what the definition is. Chapter 9 has a great discussion about privacy because people are losing control that information IS being collected. People can only hold others accountable for how the information is used.

Overall

The book will not help you master machine learning algorithms (it is not intended for that). It is not a technical book. However, if you are interested in what types of questions can be answered with all your data, this book is great. I believe the book is targeted at business people that are hoping to get a grasp of all the big data talk.

Work-Force Science

As of yesterday, I was completely new to the term work-force science. Essentially, work-force science is data analysis applied to Human Resources. It makes more sense than the old gut feeling approach. If you want to know more, see this excellent article from the New York Times, Big Data, Trying to Build Better Workers. The following quote sums up one of the key findings.

An applicant’s work history is not a good predictor of future results.

Definition of Big Data

Big data is data that exceeds the processing capacity of conventional database systems. The data is too big, moves too fast, or doesn’t fit the strictures of your database architectures. To gain value from this data, you must choose an alternative way to process it.

This definition is provided by Edd Dumbill, Editor-in-Chief of Big Data. It appeared in the March 2013 issue in the article, Making Sense of Big Data,.
