The other units do the same

Slide 16 followed the four weights entering hidden 1. The other hidden units calculate their signals in exactly the same way, but each one has its own four starting weights.

The bottle still sends:

cabernet 1, viognier 0, plummy 1, apricotty 0

That means only the cabernet and plummy weights contribute to each total. The other two weights are multiplied by 0.

Start with hidden 1:

.20 + .30 = .50

Press show hidden 2. Its weights are different, so it produces a different total. Continue through all four units.

The numbers were chosen only to give us example starting weights. They have not learned anything useful yet.

You do not need to remember the numbers. Every hidden signal comes from that unit's own incoming weights.
