Learn with me
These small models make ideas I am learning inspectable: change an input, pause a calculation, and compare the result with the mathematics. Every demo uses illustrative data and includes a static worked example.
Backpropagation, one step at a time
Follow a tiny network forward, then trace how each parameter affects its loss. Pause and scrub through the chain rule.
A leaky integrate-and-fire neuron
Change a constant current and inspect membrane voltage and exact spike times. This is an educational model of current learning.
EEG bands, separated
Toggle delta through gamma ranges in a synthetic signal. See what frequency selection does—and what it cannot tell you about a brain.
