Creating Facebook Network Graphs

I found out about Neo4j in Mark Jackson's blog and then found this post by a Neo4j employee explaining how to chart your Facebook network of friends step by step. Not all the steps worked for me, which is probably for the better, since I had to learn cypher (the Neo4j querying language) to complete the chart.

I found a few (semi) interesting facts:

- For every direct connection I have there are 10 additional connections between my friends.

- I share over half of my connections with my wife. Though this is not bi-directional, she has many more connections than me. In the picture below I am the red dot in the middle and my wife is the red dot at the far right. Every dot between the two of us is a shared connection, while dots to my left, above and below are only mine connections.

- Most of my fiends are clustered in neat silos. This picture is a network diagram of about half of my Facebook connections. I am colored red, my wife is colored orange and other colored clusters that are not blue represent unique groups (e.g. friends from school, from work, family)

I am not all too interested in researching Facebook fiends. The interesting part is experiencing network technology that's valuable in recommendation engines, fraud detectors and social applications. Next up, I'll compare my Facebook network graph with LinkedIn.

The World of Zero Growth

Jay Forrester , the founder of System Dynamics, a man regarded by many as a legend, was a guest lecturer in SDM ’s System Design class. At 92, Forrester is still relentless at finding the true implications of public policies through system dynamic simulations and working to correct policy. His work in the 70’s and onwards on the limits to growth led him to believe that people are consuming and growing beyond the world’s capacity and that disastrous consequences will follow. The implication of this belief is harsh; humanity should stop striving for growth and instead maintain a net growth of zero. Most extreme opinions are a product of dichotomous “black and white” thinking. This case is entirely different. Extensive research, innovation and his boldness to face an unpleasant revelation created this extreme view. Forester realizes that it is futile to lobby for such changes. Policy makers cannot radically change the direction of policy without a strong support of constituents. T...

AA Problem

AA stands for Attention Allocation not Alcoholic Anonymous. Sorry for the deceiving eye catcher. PTT presentation is work I did in 2005 in the purely abstract edges of Operation Research.

For the super geeks I put a link to the full article. It’s called “Attention Allocation to Partially Observable Heterogeneous Customers – with Imperfect Treatment”, Catchy? Full AA Problem article
