A Three-Layer Example: Working on the Output Layer

Input to the output layer

Let’s calculate the combined moderated input into the final layer $X = W \cdot I$.

The inputs into this layer are the outputs from the second layer we just worked out, named $O_\text{hidden}$. The weights are those for the links between the second and third layers, named $W_\text{hidden\_output}$, not those we just used between the first and second. Therefore, we have:

$$X_{}$$ ...
