YOUR EXPERIMENT
One neuron. Endless “what ifs”.
Explore weight, bias, and learning at your own pace. This is the same experiment as your lesson; its parameters stay with you.

Three things to try
- Set weight to 0. Does changing the input still affect the output?
- Set bias to 2. Where does the line meet the vertical axis?
- Reset, then take one learning step. Did the average error decrease?
The example prices follow 3 × items + 2. They are invented to make the calculation easy to inspect. This is a linear model with no nonlinear activation.
