Choose an example to inspect the network's prediction. The target is the answer we want the network to learn.
WEIGHTS & BIASES
Inspect and edit the actual parameters

A weight controls how strongly one neuron influences the next. Bias shifts the neuron's activation threshold. Edit a value and the prediction updates immediately.
