A new algorithm predicts which Twitter topics will trend hours in advance and offers a new technique for analyzing data that fluctuate over time. CAMBRIDGE, Mass. — Twitter’s home page features a regularly updated list of topics that are “trending,” meaning that tweets about them have suddenly exploded in volume. A position on the list is highly coveted as a source of free publicity, but the selection of topics is automatic, based on a proprietary algorithm that factors in both the number of tweets and recent increases in that number.
Outline This is an introductory course in machine learning (ML) that covers the basic theory, algorithms, and applications . ML is a key technology in Big Data, and in many financial, medical, commercial, and scientific applications. It enables computational systems to adaptively improve their performance with experience accumulated from the observed data.
My PR buddy Julie Wohlberg asked me tonight if I knew any good journalists she should invite to a social media conference in Florida called SheCon . ReadWriteWeb’s Sarah Perez in Tampa was apparently inaccessible, so I took a few minutes to explore some possibilities…with web applications!

From navigating the Web in entirely new ways to seeing where in the world twitters are coming from, data visualization tools are changing the way we view content. We found the following 16 apps both visually stunning and delightfully useful. Visualize Your Network with Fidg’t Fidg’t is a desktop application that aims to let you visualize your network and its predisposition for different types of things like music and photos. Currently, the service has integrated with Flickr and last.fm, so for example, Fidg’t might show you if your network is attracted or repelled by Coldplay, or if it has a predisposition to taking photos of their weekend partying. As the service expands to support other networks (they suggest integrations with Facebook, digg, del.icio.us, and several others are in the works), this one could become very interesting.
Data visualizations can be gorgeous, but images often don't do them justice, especially if we're talking live, real-time visualizations (some of which require a lot of processing power and can't even be run on a regular desktop computer). We've dug out 7 videos of awesome data visualizations you simply must see. Skyrails Skyrails is a social network visualization system, but it can be used to visualize any graph or dataset.
