COLBY Gives us eleven points, including the meth lab. I see a map with a bunch of dots on it -- I figure you can tell me something -- maybe even find his stash house --

See how various location measures (such as arithmetic
mean, median, root-mean-square, geometric mean, and harmonic mean) change as you move points
around.

CHARLIE We know the order that the locations were arrived at -- what about doing a time series analysis of overlapping Dirichlet Tessellations? Larry considers this for a beat -- then -- LARRY Wow.

The Voronoi diagram (also called
Dirichlet tessellation) for a set of points *S* in the plane is a partition of the plane into convex polygons, each of which consists of all the points in the plane closer to one particular
point of *S* than to any other.

Colby sits at a computer, running through a SERIES OF MUG SHOTS as Don enters... DON Any luck? COLBY Facial recognition software, my brain is not. But I've been through Intel's whole dossier on The New American Front, and I'm pretty sure he isn't in there. Hooper giving us anything yet?

Facial expressions of happiness, fear, anger, and suffering can be reduced to the shapes of eyes and mouths. As
suggested by Adolphs, Tranel and Damasio, and Patrik Vuilleumier, the perceived emotions in facial expressions involve
processing by the *amygdala*.

Charlie, Amita, and Larry a swirl of activity, as, on THE MAP -- Almost an inversion of what we've previously seen; the spiderwebbed cracks are faded, and the highlighted zones are where no streets had been touched -- CHARLIE How're we doing with the cluster radius changes? AMITA Almost entered --

Cluster analysis groups data elements
according to a similarity function. In this case, the similarity function is simply the Euclidean distance function, which allows
us to group them into clusters automatically based on how close they are.
