Input + Weights

Click cells to toggle input. Right-click (or long-press) a cell to edit its weight. You can also switch “Uniform Weight” mode below.

Training uses classic perceptron update: w += lr * (target - output) * x, b += lr * (target - output).

Output + Instrumentation

See the weighted sum, activation state, and an oscilloscope-ish meter. This is intentionally “explainable.”

Standby Toggle inputs or adjust dials to see the machine respond.
If the meter feels “too sensitive,” raise the threshold or reduce weights. If you want it to learn a pattern, hit Train.
