Problem 2: THE LIGHTHOUSE RING.

A lighthouse, n harbor towns in a ring, 2n cables.

Keep exactly n so everything stays connected with no loops.

How many ways? Find the closed form.

Hint 1 is live.

Solution 1 tomorrow.

Remove a central site, retain its coupling effects. This paid tutorial derives the Schur complement and checks approximation errors in a three-site model. These exercises do not reproduce the paper’s 2D topological phase.

Sprint 9/90: linear algebra and calculus for ML.

In a narrow loss valley, gradient descent zig-zags: each step points downhill, not at the minimum. I computed the path and drew it.

And: backprop only computes the gradient. Descent does the learning.

Why are we fascinated by the right angle? 📐🤖
Math isn't just something invented at a desk – we live it. The vestibular system in our inner ear forms a biological 3D coordinate system, and grid cells in the brain map out space.

Nothing beats the mental whiplash when running on cognitive overload. If brain fog wins, fall back to tests or transpose() when conventions flip on you. Whatever you do, stay away from identity matrices when debugging... they’ll lie to you every time. ;) #matrix #linearalgebra #columnmajor #gamedev

Jordan normal form organizes matrices that can’t be diagonalized into blocks, keeping eigenvalues on the diagonal and revealing how the system behaves. Have you ever seen a non-diagonalizable matrix?
