Il disegno non è il grafo · Part 1

Due disegni dello stesso grafo possono incrociarsi in modi diversi. Kuratowski dice quando l'incrocio non dipende dal tratto.

Detection at Scale · Part 1

Uber, nel 2017, ha messo i modelli dentro un motore di regole. In produzione l'unità è la cascata.

Live studying map — every node is a pressure point that forced a new layer into the system.

[Voronoi Diagrams teaching Machine Learning] · Part 1

The mathematical evolution of a millennia-old problem — Voronoi cell formalism, Gersho's conjecture, and the limits of dimensionality.

[ML Deep Dives] · Part 1

A mathematical deep dive into Principal Component Analysis, exploring eigenvectors, eigenvalues, and variance maximization.
