Learning Algorithms Have Been Developed to Try to Accomplish Learning

question 28

Multiple Choice

Learning algorithms have been developed to try to accomplish learning in a connectionist network model. These algorithms:

• A) require a few trials
• B) provide feedback about a response
• C) suggest that nodes that are activated at the same time will inhibit each other, and thus decrease learning
• D) suggest that learning is accomplished only through forward connections (Node A activates Node B), and backwards signals (Node B sends a signal back to Node A) are not allowed
