IAP Course Coolnetworking 3.0Coolhunting and Coolfarming through Swarm Creativity

Special Course during January 2013 MIT IAP independent activities period, Jan 9 to 11, 2013. to register send e-mail to pgloor@mit.edu

This course consists of three parts, part I is the foundation for parts II and III, parts can be taken separately.

Course times: Wednesday Jan 9, Thursday Jan 10, Friday Jan 11, 2013: 03-06:00pm

MIT Web Site        

Day 1: I. How to Be an Efficient (Online) Networker

Part I is for everybody who would like to learn how they can be more efficient in their online and face-to-face networking. It consists of the twenty rules for networking, based on 10 years of research analyzing (online) social networks by the instructor.

General networking rules: 2 for personal and 3 for group networksOnline networking rules: 3 for e-mail, 2 for Facebook, 3 for LinkedIn3 face-to-face networking rules

As part of the course, you will create a "virtual mirror" of your own communication behavior, telling you how much of a “star” or a “galaxy” you are, analyzing your own Facebook and e-mail networks. You will use the new Condor 3.0lite, which allows easy download of individual Facebook and E-Mail networks. To experiment with the coolhunting software tools you will need to bring your own laptop with a working WiFi connection. You will get the software on the first course day on a USB memory stick.

Modularity and community structure in networks


Via luiy
more...
luiy's curator insight, May 10, 2013 9:25 AM

Many networks of interest in the sciences, including a variety of social and biological networks, are found to divide naturally into communities or modules. The problem of detecting and characterizing this community structure has attracted considerable recent attention. One of the most sensitive detection methods is optimization of the quality function known as “modularity” over the possible divisions of a network, but direct application of this method using, for instance, simulated annealing is computationally costly. Here we show that the modularity can be reformulated in terms of the eigenvectors of a new characteristic matrix for the network, which we call the modularity matrix, and that this reformulation leads to a spectral algorithm for community detection that returns results of better quality than competing methods in noticeably shorter running times. We demonstrate the algorithm with applications to several network data sets.

 

 

Example applications


In practice, the algorithm developed here gives excellent results. For a quantitative comparison between our algorithm and others we follow Duch and Arenas [19] and compare values of the modularity for a variety of
networks drawn from the literature. Results are shown in Table I for six different networks—the exact same six as used by Duch and Arenas. We compare modularity figures against three previously published algorithms: the betweenness-based algorithm of Girvan and Newman [10], which is widely used and has been incorporated into some of the more popular network analysis programs (denoted GN in the table); the fast algorithm of Clauset et al. [26] (CNM), which optimizes modularity using a greedy algorithm; and the extremal optimization algorithm of Duch and Arenas [19] (DA), which is arguably the best previously existing method, by standard
measures, if one discounts methods impractical for large networks, such as exhaustive enumeration of all partitions or simulated annealing.

Vizalizer is an interesting tool that lets you create infographics and data visualizations. In my opinion, it is more suitable for business but ingenious people may find how to use it in education as well.

The basic version is free but it has limitations.

To explore some of the insights that a people flow focussed visual market can provide, we have selected to investigate the top 4 Australian banks; ANZ, Westac, NAB and the Commonwealth. The Australian banking industry has been somewhat protected by anti-merging laws that govern these top four banks. This has led to a polarisation of the market around the ‘big four’, making it difficult for the smaller banks to grow to compete on  level terms. We used the Linkedin Company insights feature to mine the people flows around these four major banks. This feature provides the top 5 sources only....
