Anyone who works in healthcare—or who has pondered, even fleetingly, how it differs from other sectors of the American economy—likely won’t be surprised to hear it’s the final frontier for predictive analytics.

Clustering idea for very large datasets

Let's say you have to cluster 10 million points, for instance keywords. You have a dissimilarity function, available as a text file with 100,000,000 entries, each entry consisting of three data points:

Keyword A, Keyword B, distance between A and B denoted as d(A,B)

So, in short, you can perform k-NN (k-nearest neighbors) clustering or some other types of clustering, which typically is O(n^2) or worse, from a computational complexity point of view.…

Do we really have a data obesity problem?

There has been a few people questioning the value of big data recently, and predicting that big data is going to get smaller in the future. While most of these would-be oracles are traditional statisticians working on small data and worried about their career, or practitioners in small countries (Canada and France in particular) who do not have access to big data, I was surprised to see Mike Jordan - a famous machine learning professor at Berkeley - …

A Comprehensive List of Big Data Statistics

This article was originally posted on Wikibon. Here I selected a few out of the dozens statistics. Enjoy the reading, and visit the original article: it also features a nice infographic on big data. It would be interesting to add stats about sensor data, or data used in engineering (NASA etc.) For instance, how many data points are used to make weather forecasts? How many synthetic molecules are simulated each…

Big data is cheap and easy

Big data is not expensive. You can process 10 terabytes of data per year on collocated servers using open source tools (Python - I do it in Perl), using your own home-made Hadoop system if needed, to score 100 billion transactions, all for less than $1,000 per year. It requires a bit of…

My thoughts on big data and data science: no, it's not hype

Denying that big data is a new paradigm (post year 2000) is like saying that the human population has been huge for a long time: if we can handle 10 million human beings as we did a few thousand years ago, we can handle 10 billion today the same way, even one trillion. It's the same as saying that data flowing at 10 million rows per day can be processed and analyzed the same way as 10 billion or one trillion per…
