Oracle Approximating Shrinkage
Trace the finite-dimensional coefficient rather than assuming library equivalence.
Keyboard: Tab to a control; native arrow keys change sliders. Alt + Right steps, Alt + Left goes back. Reduced-motion Play advances one state only.
- 1. Compute ML empirical covariance
- 2. Trace C and trace C²
- 3. Retain original 2/p coefficient terms
- 4. Handle isotropy and blend target
