A new version of nxviz is released!
In this update, I have added a declarative interface for visualizing geographically-constrained graphs. Here, nodes in a graph have their placement constrained by longitude and latitude.
An example... (read more)

For any problem that we think is machine learnable, having a sane baseline is really important. It is even more important to establish them early.
Today at ODSC, I had a chance to meet both Andreas Mueller and Randy Olson. Andreas leads
