The Exploration of Solar Storm Data Using JupyterQ

7 Jun 2018 | , , , ,

At Kx25, the international kdb+ user group conference held on May 18th, I made a presentation that demonstrated how to use a JupyterQ notebook to perform analytics on solar storm data. My experience working with solar storm data began last year when I was a visiting data scientist at the NASA Frontier Development Lab (FDL) in Mountain View, California. The FDL is hosted by the Search for Extraterrestrial Intelligence Institute (SETI): a not-for-profit research organization founded in 1984, whose purpose is to drive research in the space sciences. Within SETI, FDL is an applied artificial intelligence research accelerator established to maximize new AI technologies and apply them to challenges in the space sciences.

On May 18th, we hosted Kx25, the largest international kdb+ user event ever. Having the opportunity to get broad feedback from our user community is a hugely important exercise for us. We know that many of our users have built their careers around kdb+, and we recognize our responsibility to them. That is why we work so hard to constantly improve the world class software we deliver. Kx is unique in its facility to both listen, and respond, with significant changes to each new annual release of kdb+ and our supporting range of products, solutions and tools.
