So in summary, spectral clustering builds an affinity matrix of the data points.

In addition, it's multi spectral.

Identical in shape, size, spectral content.

We now talk about spectral clustering.

Let me illustrate this once again with the data set that has a different spectral clustering than a conventional clustering.

For instance, you see the spectral line of the gold is the only spectral line in the spectrum of the Sun.

Mass communication and mass transit.

This is called affinity based clustering or spectral clustering.

Spectral partitioning, L1 minimization. This comes from the optimization community.

less mass than all mass in stars.

Now the key element of spectral clustering is called the affinity martrix, which is a 9 by 9 matrix in this case, where each data point gets graphed realtive to each other data point.

The fundamental idea of spectral clustering is to cluster by affinity.

So spectral clustering gets annotation of affinity to make clustering happen.

So let me look at the simple example for spectral clustering that would also work for K means or EM, but they'll be useful to illustrate spectral clustering.

Bing! That's data. Data, data, data.

And each proton has an atomic mass of one, in atomic mass units, and each neutron has an atomic mass of one atomic mass unit.

And it turns out once again that spectral sensitivity is very important here.

And once again, it's balanced. The scale is balanced. This mass, total mass is equal to this total mass.
