blog » Hexbins! Binning is a general term for grouping a dataset of N values into less than N discrete groups. These groups/bins may be spatial, temporal, or otherwise attribute-based. In this post I’m only talking about spatial (long-lat) and 2-dimensional attribute-based (scatterplot) bins. Such binnings may be thought of as 2D histograms. This may make more or less sense after what lies beneath. If you’re just after that sweet honey that is my code, bear down on my Github repository for this project — hexbin-js. Rectangular binning The simplest 2D bin is rectangular. The above is a shot from a little example I produced on jsFiddle, while learning Mike Bostock’s fantastic D3 JavaScript library for HTML and SVG data-binding and visualization. Binning can be good for both the users and the creators/developers of static or interactive thematic maps or other visualizations. So anyway, binned representations can be beneficial for both users and creators. Hexagonal binning Adler writes, Hex history and theory

Google Plus SEO: The Ultimate Google+ SEO Guide This comprehensive Google+ SEO guide covers every aspect and angle of Google+ and how it impacts search. My normal TL;DR has been replaced with a Google+ SEO Best Practices section located at the bottom of this post. I will be periodically updating this post (updated January 23, 2012) as things inevitably change. Please don’t hesitate to comment or contact me with observations or when certain features change. I also thank the many people (on Google+) who helped in the research phase of this guide. Google+ Search Most of the attention is on the integration of Google+ in Google search results. Google+ Search Facets Google+ search queries return results with a standard selection of facets. Sometimes Google selects these facets for you. You can select certain types of content using what I call the content facet. This is all pretty self explanatory. Here you can select what universe of results you want to search. At present you can search for Google Check-ins in certain cities. Yup. Search+

G+ for Organisations and Businesses Using Google Plus for Business and Organisations of all sizes. How Google plus and the social layer will transform how organizations work for years to come. Introduction When I first got involved with understanding Google over ten years ago, I was taught one central principle: Relevance. Google’s +Vic Gundotra says that they have added a “social layer” across Google’s products and services. The ‘social layer’ integrates. Google+ is at the centre of integration of the products and services. *this is a very interesting component, network weighting, that could well determine ‘which’ results appear, from ‘who’ as well as for ‘whom’. What does this mean for business and organisations? Let’s take some examples using the Commoogle page +Commoogle as a quick case study. Note, this why managers on a page are so important to get right – the right manager for the task has the right people in the right circles Example 1 1. Example 2 1. Why every business will want to be on Google+ very soon… Search… 2. 3.
APEXvj - Visualize your favourite tunes online Data Science Toolkit Gephi, an open source graph visualization and manipulation software Protovis Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example. Protovis is no longer under active development.The final release of Protovis was v3.3.1 (4.7 MB). This project was led by Mike Bostock and Jeff Heer of the Stanford Visualization Group, with significant help from Vadim Ogievetsky. Updates June 28, 2011 - Protovis is no longer under active development. September 17, 2010 - Release 3.3 is available on GitHub. May 28, 2010 - ZOMG! Getting Started
MALLET homepage MALLET is a Java-based package for statistical natural language processing, document classification, clustering, topic modeling, information extraction, and other machine learning applications to text. MALLET includes sophisticated tools for document classification: efficient routines for converting text to “features”, a wide variety of algorithms (including Naïve Bayes, Maximum Entropy, and Decision Trees), and code for evaluating classifier performance using several commonly used metrics. Quick Start / Developer’s Guide In addition to classification, MALLET includes tools for sequence tagging for applications such as named-entity extraction from text. Algorithms include Hidden Markov Models, Maximum Entropy Markov Models, and Conditional Random Fields. Topic models are useful for analyzing large collections of unlabeled text. Many of the algorithms in MALLET depend on numerical optimization. The toolkit is Open Source Software, and is released under the Apache 2.0 License.
