Oct 26, 2013 — Cluster Validation — Unsupervised clustering can be tough in situations when we just don’t know “the right number” of clusters.  In toy examples we can sometimes use domain knowledge to push us toward the right answer, but what happens when you really haven’t... Read more

Sep 11, 2013 — Functional Brain Network Visualization — Now that we have (finally) come up with a correlation matrix to describe the relationship of voxels across the brain, let’s explore some simple methods from graph theory.  To make this analysis somewhat more simple, I’ve thresholded my brain network...

Sep 9, 2013 — Tracing a Functional Brain Network — I’m reading about different ways to understand and process functional data, and so methods from graph theory serve as good candidates.  I’m excited about these methods simply because I’ve never tried them out before. Creating the Graph Assess Correlations between... Read more
