Use Data Science to Help The World (Data Without Borders)

Data Without Borders

Jake Porway started Data Without Borders because he attended a hack-a-thon and the groups came up with apps that didn’t really better the world very much. I believe he used the word, “unfulfilling” to describe the apps. He decided to create a way to provide organizations (Government or non-profit) with access to data scientists. His thinking goes like this. There are lots of data scientists that love to work with data. There are great organization with lots of data. If the two can be matched together, what amazing things can be done? Data Without Borders hopes to find out.

Data Without Borders organizes a bunch of DataDives, which are weekend hack-a-thons that match up a group of data scientists and developers with data.

Jake concluded with some wonderful remarks:

What if we started using data not just to make better decisions about what kind of movies we wanted to see? What if we started using data to make betters decisions about what kind of a world we wanted to see?

What is Data Without Borders looking for?

Think Stats – An Online Statistics Book For Programmers

Previously I mentioned that online statistics learning resources are not abundant.

Well, here is a new online book for learning statistics. It is geared towards programmers, and it looks to be a great fit for people wanting to learn data science.  Here is a small excerpt from the Preface:

It emphasizes the use of statistics to explore large datasets.

I have only had time to quickly browse the book, but it looks quite good.

Kaggle Makes Data Science Fun

The tag line for Kaggle is “We’re making data science a sport.”  They have successfully created a way to turn data science into a competition.  It is both fun, and it yields excellent results.  There is also a portion of the site dedicated for classroom use.  It is called Kaggle in Class.

Here is how it works.  A company that needs some data analyzed can contact Kaggle and host a competition.  Then data scientists all over the world can compete to find the best solution. The company benefits from having many algorithms and techniques applied to the same data set.  Many more algorithms are applied than what the company could run without Kaggle.  The contestants benefit from networking, pre-cleaned data, and learning from others.  It is a win/win situation. Plus, the winner gets prize money.

Currently, the large featured competition is the Heritage Health Prize. It is a $3,000,000 competition to identify individuals that will be admitted to the hospital in the next year.  The contest lasts until April 2013.

This is definitely a site I want to be involved with in the future.  I just wish they could make it a spectator sport as well.

16 Companies Hiring Data Scientists Right Now

Data Scientist is the hot new job for 2012.  Does this job really exist?  Who hires these people? Are companies currently hiring? The answers are: yes, lots of companies, and yes. I decided to spend last night looking for companies that are currently hiring data scientists.  It did not take long to compile a pretty good list.

Learning Statistics for Data Science

Statistics – This is a topic that could use some more attention from the online community.
I would love to see Stanford (or Coursera) offer a free statistics course online much like the other free courses online.

I did find a series of Youtube videos by Daniel Judge, a Professor in the East Los Angeles College Mathematics Department. The videos start at the very beginning of statistics. I have watched a couple of the videos, and they seem quite good. Daniel does a nice job of explaining the information. Here is the first video in the series.

Stay tuned to the blog in case other stats options appear online. Also, please leave a comment if you know of some good online statistics resources.

What Makes a Good Data Scientist?

Jeremy Howard is the Chief Scientist at Kaggle. At the end of this interview, from the Strata Conference 2012, he identified 4 simple traits that a data scientist needs.

  1. Creativity
  2. Open-mindedness
  3. Tenacity
  4. A Good Skillset

Jeremy Howard of Kaggle at Strata 2012

In this brief interview he covers a range of other data science topics:

  • Big Data is an engineering problem
  • Analytics generate value/insight from data
  • Predictive Modeling is about answering a question – build a model to do that
  • Is Data Science about tools or people? – watch the video for Jeremy’s answer
  • And others…
