LSST (Large Synoptic Survey Telescope)
With loads of content and hype about Data Science, Analytics and Big Data coming up every day, I felt compelled to share my journey and experiences in exploring this space. Here, I intend to begin a series of posts on the subject stripped it down to it's core (as I understand it) and than building upon it.
While there are a whole bunch of directions these subjects could be approached from, I present here the path that I found most convenient to tread. I would like to call it the path…

It is the most difficult to digest and comprehend book to date out of all I have recently read. At the same time it was pure fun.
Why so hard, I guess I need to blame myself because this book unexpectedly turned out to be more from the Academia world where my skills in Algebra and Statistics faded out over time than from the practical world where I spend my productive time. At the same time it was pleasant to have a feeling of being a student again.
Nevertheless, the book…

There isn’t any specific standard to model data warehouse. It can be built either using the “dimensional” model or the “normalised” model methodologies. Normalised model normalises the data into third normal form (3NF) whereas dimensional model collects the transactional data in the form of facts and dimensions. Normalised model is easy to use as we can add related topics without affecting the existing data. But one must have good knowledge of how data is associated before performing…

In the drive towards the semantic web, mailing lists are ripe, low hanging fruit. They are full of wisdom totally inaccessible to the casual user. To unlock this wealth of knowledge for our apps, we need it in a format like the Stack Exchange data dump.
This data dump format is to Stack Exchange what JSON is to JavaScript: an exchange format that spawns growth in ecosystems…

Here I am talking about small countries with 10 million or less inhabitants, with good universities and high standard of living: places such as Switzerland, Singapore, Ireland, Belgium, Greece, Netherlands etc.
For data scientists, the challenges are as follows:

Above is a distribution of price differentials for the Dow Jones Industrial Average from the 1930s. The image was generated by one of my programs called Storm. I posted a few images from the same application in other blogs. If I recall correctly, the more volatile differentials (closer to the action) are at top; the more stable differentials (further from the…

This list is a bit old (I think 2011), but it features a bunch of very interesting people, true data scientists who can't afford wasting their time to post on Twitter - unlike other similar lists published by journalists.

You like working with data. You’ve completed a few data science courses and enjoyed them. Now what?
I second Don VanDemark’s enthusiasm for course sequences, specialization tracks, and certification offerings. Whether through traditional brick-and-mortar schools, on-line offerings, or bootcamps, the carefully-planned curricula and (depending on the program) personal…

Specifically designed in the context of big data in our research lab, the new and simple strong correlation synthetic metric proposed in this article should be used, whenever you want to check if there is a real association between two variables, especially in large-scale automated data science or machine learning projects. Use this new metric now, to avoid being accused of reckless…
