Raw EC Notes on Ringo Spectral Problem


Finshed Haskell code. It's a naked, raw EC. No frills but I have full control of everything.

Tried "Hail Mary" on 20 PCA cols and got ..

Messy printout but it says ...

Next Tried only 3 PCA columns

No better. The MSE is still 1084

Try a Tiny Test Matrix

The $\alpha's$ for this are, $[2,3,4]$

Let's run it !

A bit better ...

So now it appears that we need to reduce the search space by limiting the $\alpha's$ somehow. I'll have to think about this.
