Crossfilter Fast Multidimensional Filtering for Coordinated Views Crossfilter is a JavaScript library for exploring large multivariate datasets in the browser. Crossfilter supports extremely fast (<30ms) interaction with coordinated views, even with datasets containing a million or more records; we built it to power analytics for Square Register, allowing merchants to slice and dice their payment history fluidly. Since most interactions only involve a single dimension, and then only small adjustments are made to the filter values, incremental filtering and reducing is significantly faster than starting from scratch. Crossfilter uses sorted indexes (and a few bit-twiddling hacks) to make this possible, dramatically increasing the perfor­mance of live histograms and top-K lists.

“Drug Deal” Network Analysis with Gephi (Tutorial) Via a trackback from Check Yo Self: 5 Things You Should Know About Data Science (Author Note) criticising tweet-mapping without further analysis (“If you’re making Gephi graphs out of tweets, you’re probably doing more data science marketing than data science analytics.

7 Awesome Visual Alternatives to Google Docs You don't need a degree in rocket science to know that visually organized data appeals more to students than plain text-based scribble. The visual stimulus is quickly captured by the brain and requires way less processing to understand and code it than written text.

The web tools below have almost the same collaborative features Google Docs provide and they also have an added feature which is that of capturing and organizing data visually.

I was pleased and frankly surprised to receive 91 submissions to my dashboard design competition. Surprised because designing a student performance dashboard from scratch based on the data that I provided was not a trivial task. I was especially pleased to find a dramatic improvement over the general quality of entries since the last competition that I judged back in 2006. Almost every entry exhibited qualities that far surpass the dashboards that are typically produced and used today.

Tips for Structuring Better Brainstorming Sessions Brainstorming is widely used by teams as a method to generate ideas and solve problems. However, many brainstorming activities are flawed and can end up hurting creativity rather than helping spur ideas. It has been well documented that traditional brainstorming, where groups come together and toss out ideas one by one, is often a flawed process. Issues with brainstorming include: Weka 3 - Data Mining with Open Source Machine Learning Software in Java Weka is tried and tested open source machine learning software that can be accessed through a graphical user interface, standard terminal applications, or a Java API.
