| • | The obvious
approach is just to solve a set of |
|||||||||
| simultaneous
linear equations, one per meal. |
||||||||||
| • | But we want a
method that could be |
|||||||||
| implemented in a
neural network. |
||||||||||
| • | The prices of the
portions are like the weights in |
|||||||||
| of a linear
neuron. |
||||||||||
| • | We will start
with guesses for the weights and |
|||||||||
| then adjust the
guesses to give a better fit to the |
||||||||||
| prices given by
the cashier. |
