8.1 Feed-Forward Networks
Figure 8.2 shows a feed-forward network with one hidden
layer. This network attempts to fit the model
for the output unit
.
Feed-forward means that information can only flow forward from
the input units to the first hidden layer, from the first hidden layer
to the second hidden layer, and so on.
Information cannot flow between the units of one layer.
