Aug 14, 2026 New blog post: What Is Negative-Shifted Gradient Descent—When the Useful Estimator Is Not an Endpoint — how a finite-time signed path passes smoothly through the would-be endpoint pole and creates head anti-shrinkage with controlled lower-spectrum exposure. Aug 07, 2026 New blog post: The Spectrum Was Known to Be Biased. Why Did PCR Keep Inverting It? — de-floored PCR and correcting the spectral floor before inversion. Aug 06, 2026 New blog post: Shrinkage Is Not a Universal Law — when expansion, rather than shrinkage, is the right correction in overparameterized prediction.
