Old Mathematics Quietly Powers Modern AI
Eigenvalues shaped search in 1990 and ranked the web in 1998. They still sit under embeddings, PCA and LoRA. The small end of the spectrum may have one more use.

MG Signal · Machine Learning · Survival Analysis
Everyone Predicts Failure. Few Predict Time.
Failures were rare, so most of our data wasn't failure data. Survival analysis let every observation contribute what it actually knew, instead of forcing a label.

Why We Stopped Using Western Electric Rules
The zone rules assume a distribution most real processes don't have. We kept Rule 1, made the limits adaptive, and handled drift as a separate problem.
