- Back-propagation repeats until the error signal is 1
- Weights should be changed to allow the output signal to match the correct signal
- Whether or not the output units are given you the correct information they are adjusted
- Responding is modified to match the correct response
3. In the connectionist approach, what does the error signal determine?
- How knowledge is represented in the distributed activity of many units
- How strongly an incoming signal will influence the activity of the next unit
- Difference between actual activity of each output unit and the correct activity
- Whether the output units are adjusted to give the correct information
4. Semantic networks show a cognitive economy. What is this?
