I had a great time presenting my new webinar yesterday, thanks to everyone who attended "The Rise of Data Science in the Age of Big Data Analytics" and especially those who submitted questions. Sorry I didn't have time to get to them all, but feel free to ask here in ... [Read more...]

More data apps spawned by Sandy

October 31, 2012 | David Smith

As the clean-up continues on the eastern seaboard, I wanted to follow up on Monday's post on tracking Hurricane Sandy with Open Data with a couple of other R-based data applications spawned by the storm. Josef Fruehwald created an R script to tap into local weather sensors to keep track ... [Read more...]

On Thursday next week (November 1), I'll be giving a new webinar on the topic of Big Data, Data Science and R. Titled "The Rise of Data Science in the Age of Big Data Analytics: Why Data Distillation and Machine Learning Aren’t Enough", this is a provocative look at why ... [Read more...]

Ryan Rosario on Parallel programming in R

August 17, 2012 | David Smith

Earlier this year data scientist Ryan Rosario gave a talk on parellel computing with R to the Los Angeles R User Group, and he recently made the slides from the talk available online. They're a great resource for anyone looking to make use of multi-processor systems a Hadoop based architechure ... [Read more...]

Success does not require understanding

July 23, 2012 | Derek-Jones

I took part in the second Data Science London Hackathon last weekend (also my second hackathon) and it was a very different experience compared to the first hackathon. Once again Carlos and his team really looked after us. The data was released 24 hours before the competition started and even though ... [Read more...]

Preparing public data for analysis with R

July 18, 2012 | David Smith

In most data science applications, preparing the data is at least half the job. Finding where the data lives, figuring out how to access it, finding the right records, filtering, cleaning and transforming the data ... all of this has to be done before the statistical analysis can even begin. Fortunately, ... [Read more...]

The R packages in a data scientist’s toolbox

July 17, 2012 | David Smith

John Myles White, self-described "statistics hacker" and co-author of "Machine Learning for Hackers" was interviewed recently by The Setup. In the interview, he describes his some of his go-to R packages for data science: Most of my work involves programming, so programming languages and their libraries are the bulk of ...

A new open journal on Data Science

July 4, 2012 | David Smith

Springer has introduced a new open, peer-reviewed journal focused on Data Science: EPJ Data Science. What makes this a Data Science journal is novel uses of statistics, data analysis, computer techniques and public data sources to research a topic in another domain, rather than methodological research. Here are a few ... [Read more...]

Modeling Trick: Masked Variables

July 1, 2012 | John Mount

A primary problem data scientists face again and again is: how to properly adapt or treat variables so they are best possible components of a regression. Some analysts at this point delegate control to a shape choosing system like neural nets. I feel such a choice gives up far too ... [Read more...]

integrating R with other systems

June 16, 2012 | Harlan

I just returned from the useR! 2012 conference for developers and users of R. One of the common themes to many of the presentations was integration of R-based statistical systems with other systems, be they other programming languages, web systems, or enterprise data systems. Some highlights for me were an update ... [Read more...]

More on birthday probabilities

June 15, 2012 | David Smith

Last week, Joe Rickert used R and four years of US Census data to create an image plot of the relative probabilities of being born on a given day of the year: Chris Mulligan also tackled this problem with R, but this time using 20 years of Census data from 1969 to 1988. ... [Read more...]

Selection in R

June 1, 2012 | John Mount

The design of the statistical programming language R sits in a slightly uncomfortable place between the functional programming and object oriented paradigms. The upside is you get a lot of the expressive power of both programming paradigms. A downside of this is: the not always useful variability of the language’... [Read more...]
