Any hope that you could post a tutorial or some minimal working example that includes how you render the colors and so on using matlab?<br /><br />Be much appriciated.<br /><br />/CasperAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-15418143.post-78052567261716988802011-04-16T00:28:58.786-05:002011-04-16T00:28:58.786-05:00hello from the future, april 2011.

Each vertex is a particular car instance (an exemplar), and an edge connects two car exemplars if they are considered similar by my distance function learning algorithm. Not all cars are similar to all cars, and the magic is figuring out which ones should connect to which others.<br /><br />I describe the visual memex building process in my <a href="http://www.cs.cmu.edu/~tmalisie/projects/nips09/" rel="nofollow">NIPS 2009 paper: Beyond Categories: The Visual Memex Model for Reasoning About Object Relationships</a>.<br /><br />The colors here are arbitrary, the actual edge length is an output of the graphviz optimization process, and not necessarily related to the edge "similarity" strength.Tomasz Malisiewiczhttps://www.blogger.com/profile/17507234774392358321noreply@blogger.com
