Data Science Education gets personal

by Joseph B. Rickert It is difficult to imagine that there is anyone on the planet with an internet connection and a desire to learn something new who has not at least looked into taking a massive open online course (MOOC). Last Fall, in an 11/4/12 article, the New York Time declared the Year of the MOOC and quoted one of Coursera’s founders, Andrew Ng, of Stanford Machine Learning fame, as boasting that with over 1.7 million students “Coursera was growing faster than Facebook”. This year with both Udacity and Harvard and MIT backed edX offering interesting and challenging courses the growth of MOOC enrolment must be astounding indeed. I think this is all good and I have written about it before . Being the perpetual student, I have looked over the syllabi of quite a few courses that seem to be pretty exciting, but I am struggling to carve out the time to devote to them.  MOOC courses are “free”, but for a working professional they not without opportunity costs. In fact, it is not clear that a course designed to add value to 100,000 plus people at one time is the most effective way for professionals working in or around data science to make progress. Tony Ojeda of the R-users-DC saw the interest professionals have in learning more about data science, and realized that even with the prevalence of MOOC courses there are educational needs that are not being met. In a recent email Tony wrote: I started attending data meetups like R Users DC and Data Science DC about a year and a half ago … and these events really made me realize that there are a bunch of people out there who, like me, wanted to learn more about data science, machine learning, and analytics.  However, I noticed that there isn't really a set path for people that want to get started learning data science.  It all depends on your current context and learning how to apply the methods and tools to what you're currently doing. Tony also noticed that many of the people attending the meetups were very knowledgeable about statistics, programming or other aspects of data science. And, as he describes it: I'm sort of an efficiency freak, so I automatically thought, “It would be awesome if I could just find someone who knew more than me about whatever I'm trying to do so that I could get past these hurdles and get my work done."  The result of Tony’s musings was that on January 9th of this year he announced www.sagebourse.com , a bare bones site for matching students with data science tutors in the greater DC area (including Maryland and Virginia). Students accessing the sight can express and interest in being tutored in either Data Science or Programming. Currently, Data Science topics are limited to Statistics, R, Machine Learning, Matlab/Octave or Excel.  The programming languages listed are: Python, Ruby, Java, Javascript, C, C++, Perl and PHP. In addition to these topics, sagebourse.com is also looking for tutors in SAS, SPSS, Stata, Hadoop, Access and Data Visualization. Tutors who register with the sagebourse.com “bid” on the gig by providing the hourly rate at which they are willing to teach a subject. When students register with the site they fill out a form indicating the subject they want to be tutored in, provide contact information and indicate where they would want the tutoring to take place. Students then receive an email with bids from several tutors. Presently, the process of matching tutors with students takes a few days depending on the responsiveness of tutors and students. These are still very early days for sagebourse.com. About 20 tutors have registered with the site and according to Tony they have already had a “handful” of successful tutoring sessions. Statistics and R are by far the most popular areas of expertise professed by the tutors who have registered, and “In terms of demand from students, it has been R, Statistics, and Machine Learning in that order”.   I am excited about what sagebourse.com is trying to do, and I hope that it can make a big, positive contribution to the R community.

There will be 50 billion Internet connected devices by 2020. Today, every manufacturer has a propriety protocol and an app. How do we securely integrate these "things" into our lives and businesses in a way that we can easily control and manage? Even better, how do we integrate these "things" so that they control and manage each other so our lives become more convenient or our businesses become more profitable and/or safe? We have heard that the best interface is no interface. In his session at Internet of @ThingsExpo, Chris Matthieu, Co-Founder & CTO at Octoblu, Inc., will discuss how these devices generate enough data to learn our behaviors and simplify/improve our lives. What if we could connect everything to everything? I'm not only talking about connecting things to things but also systems, cloud services, and people.

Last week, while in San Francisco, I used the Uber app and service four times. All four experiences were great, although one of the drivers stopped for 30 seconds and then left as I was walking up to the car. He must have realized I was a blogger. None the less, the next car was just a minute away and I suffered no pain. In this article, my colleague, Ved Sen, Global Head, Advisory Services Social, Mobile and Sensors at Cognizant shares his experiences and insights.
We are reaching the end of the beginning with WebRTC and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) irreversibly encoded. In his session at Internet of @ThingsExpo, Peter Dunkley, Technical Director at Acision, will look at how this identity problem can be solved and discuss ways to use existing web identities for real-time communication.

The P2P shift will impact many areas of our lives, from mobile communication, human interactive web services, RTC and telephony infrastructure, user federation, security and privacy implications, business costs, and scalability. In his session at Internet of @ThingsExpo, Erik Lagerway, Co-founder of Hookflash, will walk through the shifting landscape of traditional telephone and voice services to the modern P2P RTC era of OTT cloud assisted services.
While great strides have been made relative to the video aspects of remote collaboration, audio technology has basically stagnated. Typically all audio is mixed to a single monaural stream and emanates from a single point, such as a speakerphone or a speaker associated with a video monitor. This leads to confusion and lack of understanding among participants especially regarding who is actually speaking. Spatial teleconferencing introduces the concept of acoustic spatial separation between conference participants in three dimensional space. This has been shown to significantly improve comprehension and conference efficiency.
The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, will discuss single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example to explain some of these concepts including when to use different storage models.
