UCLA is having a big data conference on Thursday and Friday Mar 27, 28 2014. The conference is organized by four computer science and genomic biology types. Speakers cluster [one of the rare appropriate uses of cluster analysis I know of] into three types of folks. Big biologists [they must be big, they're doing big data] doing big data, genomic stuff; computer scientists doing topic models, and a few math…Continue

This is data science from the trenches - both a case study, and a tutorial for data sciencist candidates. Here I illustrate how gut feelings, carefully selected data (rather than getting granular data), full understanding of business (horizontal knowledge), high level vision, and outsourcing (to make data science almost free) combined together, makes a data science project…Continue
Data empowers business: it gives us the information we need to make the decisions that drive enterprises, industries, and economies. Big Data enables us to collect a massive amount of information (that we can store, search, share, and analyze) to bring us closer to the goal of finding trends that lead to smarter business decisions.

The field of data science continues to grow, and with it come thought leaders who contribute to the industry through outreach and education. Many of the data science professors teaching today are leaders in the big-data field, speaking at conferences, writing books, and even creating groundbreaking big-data developments themselves. Find out which schools boast the most influential leaders in the data science industry.Continue
With all of the discussion about Big Data these days, there is frequest reference to the 3 V’s that represent the top big data challenges: Volume, Velocity, and Variety. These 3 V’s generally refer to the size of the dataset (Volume), the rate at which data is flowing into (or out of) your systems (Velocity), and the complexity (dimensionality) of the data (Variety). Most practitioners agree that…Continue
