Filtergraph and the power of visual exploration: A web-based tool for exploring high-dimensional data sets, Filtergraph came out of the lab of Astrophysicist Keivan Stassun. It has helped researchers make several interesting discoveries including a paper (that appeared in Nature) on a technique that improves estimates for the sizes of hundreds of exoplanets. For this particular discovery, Keivan tasked one of his students to play around with Filtergraph until she discovered “interesting patterns”. Her visual exploration led to an image that inspired the discoveries contained in the Nature paper.
RunMyCode: I was glad to see several sessions on the important topic of reproducibility of research projects and results (I’ve written about this topic from the data science perspective here and here). Beyond just sharing data sets, RunMyCode lets researchers share the data and computer programs they used to generate the results contained in their papers. Sharing both data and code used in research papers are important steps. (For complex setups, a tool like Vagrant can come in handy.) But to address the file drawer problem, access to data/code for “negative results” is also needed.
A network framework of cultural history: Scifoo alum Maximilian Schich pointed me to some of his group’s recent work on cultural migration in the Western world. I’ve seen Maximillian give preliminary talks on these results in the past (at Scifoo). He combines meticulous data collection, stunning visualizations, and network science to discover and quantify cultural patterns.
