Here are some interesting data science nuggets that I thought were interesting for a mid-January day…

The first comes from TechMASH about data science being the next big thing.  The primary nugget of note is that the supply of employees with the needed skills as data scientists – those people who really understand how to pull relevant information out of data reliably – is going to have a tough time meeting demand.  Here’s an interesting infographic on the current disconnects – for example, while 37% of “business intelligence” professional studied business in school, 42% of today’s “data scientists” studied computer science, engineering, and natural sciences.  This highlights the increasing demand for students that have solid mathematics backgrounds – it’s becoming more about knowing how you pull information from data, regardless of application.

Don’t get me wrong – to be effective applying data science, you need two things:  a subject matter expert that understands what makes sense and what doesn’t, and someone who really understands data to pull out the information.  Sometimes that can reside within one person, but it’s rare and takes many years of training to acquire the necessary excellence in both fields.   And as the demands for data analysis grow, these two areas will likely form into distinct disciplines with interesting partnership opportunities being created.

The definition of data science is still being defined, but I’m convinced it will have huge impact in the next five years.  And while the science aspects of data are starting to be defined, the engineering aspects of data and analytics are truly in their infancy…

On the same thread, here’s a Forbes article by Tom Groenfeldt on the need for data scientists, or Excel jockeys, or whatever they will be called in the future.  For some companies, the move to “data science” is quite apparent, but for others, the current assemblance of business professionals that have figured out the ins-and-outs of Excel spreadsheets work quite well.  This is likely a snapshot of where things are today, but I do believe that as the questions we ask of the data get more complicated, we will clearly see the need for a more rigorous science-based discipline to data wrangling…

The last tidbit is from the Wall Street Journal about the healthcare field being the next big area for Big Data.  I do think that healthcare is ripe for leveraging data, and I’ve written other posts on the subject.  One former Chief Medical Officer that I spoke with mentioned that one of the big problems is just getting the data useable in the first place.  He said that, as of today, 85% of all medical records are still in paper form.  The figure seems a bit high to me, but I don’t really know how many patient records in various individual doctor’s offices are still sitting in folders on shelves. 

There has been a big push lately, spurred by financial support from the U.S government, for upgrading to electronic health records (EHR).   This will help to solve the data collection problem – if you can’t get data into an electronic format, you can’t utilize information technologies to pull information out of the data.

I ran across this article from the Independent today about the impacts of data algorithms, the ethics of data mining, and the future of our lives in an automated, data-crunching world.  Below is a quote from the article by Jaron Lanier, musician, computer scientist and author of the bestseller You Are Not a Gadget.

Algorithms themselves are a form of creativity. The problem is the illusion that they’re free-standing. If you start to think that information isn’t just a mask behind which people are hiding, if you forget that, you’ll pay a price for that way of thinking. It will cause you to be less creative.

If you show me an algorithm that dehumanises, impoverishes, manipulates or spies upon people,” he continues, “that same core maths can be applied differently. In every case. Take Facebook’s new Timeline feature [a diary-style way of displaying personal information]. It’s an idea that has been proposed since the 1980s [by Lanier himself]. But there are two problems with it. One, it’s owned by Facebook; what happens if Facebook goes bankrupt? Your life disappears – that’s weird. And two, it becomes fodder for advertisers to manipulate you. That’s creepy. But its underlying algorithms, if packaged in a different way, could be wonderful because they address a human cognitive need.

I think this is a really great read for anyone who’s interested in data, algorithms, and their impact on society – there’s a lot of really good stuff to take in.  You can read the entire article here…

This is the very question asked by Colin Hill, CEO and co-founder of GNS Healthcare, a healthcare analytics company.  Hill hopes to make the case that healthcare can benefit from what a recent McKinsey report calls “the next frontier for innovation, competition and productivity.”  

I think Hill is onto something, especially with this insight:

What will healthcare look like in the year 2020?  One thing is certain: we can’t afford its current trajectory.  Left unchecked, our $2.6 trillion in annual spending will grow to $4.6 trillion by 2020, one-fifth of GDP.  With almost 80 million Baby Boomers approaching retirement, economists forecast these trends will likely bankrupt Medicare and Medicaid in the near future.  And while healthcare reform ignites a number of important changes, alone it does not resolve our issues.  It’s critical we fix our system now.

Something’s got to give, and better decisions from better data can yield significant healthcare savings if done right.  Saving lives and reducing costs dramatically in healthcare would qualify as one of those hard problems where disciplined approaches can yield significant results.  Here is Hill’s post on Forbes…

I ran across this interview by Fast Company with LinkedIn co-founder about his new book The Start-Up of You and the need for companies to have a data strategy, or risk losing “potentially a lot” in the future.  Here’s that brief bit from the Hoffman interview:

What do companies miss out on if they don’t have a data strategy?

Potentially a lot. If you say the way our products and services are constituted, how we determine our strategy and maintain a competitive edge against other folks–if data is a very strong element of each of these, and you’re not doing anything, it’s like trying to run a business without business intelligence. I’m not sure I have a broad enough view that I would say every company needs to have a data strategy. But I would say many companies do. I certainly think that any company that is over 20 people needs to have a technology strategy, and data is essential to where technology is going.

LinkedIn has already been on record as not worrying about Facebook taking over their business.  According to Hoffman, “People with advanced degrees are three times more likely to use LinkedIn.”

Are banks predicting divorces?  Well, if there’s data to help them predict such things, they may very well use it to optimize their business.

Forbes has a couple of posts that peek into businesses use of “big data”.  The first article talks about the race to build new analytics to solve challenges of large volumes of data.  Here’s a snippet from Tom Groenfeldt‘s post, quoting Scott Gnau, head of research and development at Teradata:

Thought leaders in a number of industries are starting to leverage the additional analytic content from big data and combine it with what they have in large volume data stores as well. It is interesting to understand social media and consumer sentiment, but when that information is analyzed in combination with traditional consumer data it provides new, rich intelligence helping companies to identify trends and react to immediate business conditions.

According to another Forbes article, there are a number of studies that show that companies that characterize themselves as ”data driven” as the best corporate performers.  Now, when we’re talking “data driven”, we mean in how the company operates, not necessarily in what it produces as technology.  Top performing companies are determined to use the data that they have (especially about themselves) to improve what they do and how they do it. 

Also, banks are on the lookout for changes that could affect how they do business with their customers, and of course, their bottom line:

Banks, for example, worry about their customers divorcing, because divorce causes a change in credit-worthiness. No problem. They can now see a divorce coming before the couple does. All from the data.

As part of the “Computer Science or Data Science” panel at Techonomy 2011 in Tucson, AZ this week, the panel explored how data science has taken its place next to computer science as a fundamental element of information technology.  New technologies are coming out seemingly every day, not only to handle big data, but to understand how to extract relevant information from the ocean of data we’re swimming in.

A company in Silicon Valley, ai-one, announced today that they have “a breakthrough method to graphically represent knowledge enables software developers to easily build intelligent agents such as Apple’s SIRI and IBM Watson”.  The technology, ai-Fingerprint, is geared toward natural language programming, allowing developers to create new technologies that use natural language as input data.  

Apple’s Siri and IBM’s Watson are definitely heading in the right direction for this type of technology.  I just bought an iPhone 4S and I’ve tested Siri out a number of times.  While Siri doesn’t get everything right (it keeps thinking my name is “Nick” when I say “Mic”), it does get more right than I expected.  I was able to send texts and e-mails to people without keystrokes, and I took some notes using the voice feature, getting nearly every word correct.  Pretty amazing stuff!…

Watson is the supercomputer that beat two longtime Jeopardy! champions, and it uses a technology approach that looks for the best answer for the questions being asked (or in this case, the best question for the answer being presented – it is Jeopardy! after all…).  These are definitely the models that should be emulated; although, ai-one’s announcement is a press release so before we see the results, let’s chalk this up at the moment as good marketing…
