We’re witnessing the rise of the graph in big data GraphLab, a popular open source project dedicated to graph analysis and machine learning, is trying to capitalize on the excitement around graphs by spinning off a commercial entity, GraphLab Inc. GraphLab creator — and University of Washington machine learning professor — Carlos Guestrin will lead the new Seattle-based company, which has raised $6.75 million from Madrona Venture Group and NEA. Graph analysis is among the hottest techniques around for making sense of large datasets, primarily by determining how tightly different data points are related or how similar they are. My LinkedIn social graph Guestrin said GraphLab’s algorithms are used in a lot of recommender systems, but he also cites fraud detection in banking networks and intrusion detection in computer networks as potential applications. One of Ayasdi’s graph-like data maps Google also famously uses a graph-processing system called Pregel as part of PageRank.

An edited version of our conversation is below. What’s the history of data visualization at GE? GE specializes in complex challenges in solving the toughest problems in the world: Infrastructure, renewable energy, affordable health care. In trying to do that, the marketing communications brand group is always searching for compelling ways to bring these challenges to life. One of our first was back in 2009, and was about causes of death. We got a tremendous response to it. How do you think about using data visualization when it comes to different audiences and stakeholders, both within your company and outside of it? Also, we’re GE. I think so.

World Bank Dataviz Freeplane 1.3.11 free download A versatile mind mapping tool Freeplane is a free and open source application for organising, visualising and sharing information. The program is a redesigned version of FreeMind, and can similarly be used to create mindmaps, although with more features and functionality. You can use Freeplane to build regular, static mindmaps, simple charts and diagrams which structure information. At its simplest you just press Ins to add a node; customise it, with an image, text, or icon; repeat the process to add other nodes, then link and organise them as you like. Freeplane goes further, though. That content can be very active. Built-in calendar and reminder tools are useful for time and project management. There's DES encryption of individual nodes or the entire map. The program can be extended with scripts and some interesting addons. And once you've finished, the map can be shared as an image, an HTML page, via Flash and more. Related Download Articles FreeMind 1.0.1 Open Source Freeware Trial Software
