Q

How does reward learning work in humans?

A

It is a process rooted in rooted in our brains reward system. Involves release of NTs such as dopamine when we do something pleasurable or rewarding. Through trial and error, human learn to associate specific actions or choices with these rewarding outcomes

Q

How does reward learning work in Artificial Intelligence?

A

In AI it is a critical component of reinforcement learning. Reinforcement algorithms use reward signals to update agent’s policy, encouraging it to repeat actions that lead to positive outcomes and avoid negative ones.

Q

How does procedural knowledge work?

A

It is a basic process of “Match -> fire”. It works with “if - then” statements or “condition - action” statements.
“If” checks buffer content (matches to the content of working memory)
“Then” fires to change the state in a buffer or request from a module

a progression from slow and deliberate rule following to a procedural stage where aspects of performance become more automatic, faster, and accurate

93
Q

What are the 3 stages of skill learning?

A
  • Declarative Knowledge: As task is acted out it begins to trigger procedural knowledge that carries out performance
  • Procedural Knowledge: Builds up as declarative knowledge is repeatedly practiced. With practice performance goes up and errors go down
  • Actions rely on procedural knoweldge: actions become increasingly automatic, fast, and accurate. These actions can. be increasingly refined
