What is an optimizer function?
|
||||
answers:
|
||||
- A function that increases the accuracy of a model's predictions.
|
||||
- A function that implements the gradient descent and backpropagation algorithms for you.
|
||||
- A function that reduces the time a model needs to train.

What can happen if the agent does not have a good balance of taking random actions and using learned actions?
|
||||
answers:
|
||||
- The agent will always try to minimize its reward for the current state/action, leading to local minima.
|
||||
- The agent will always try to maximize its reward for the current state/action, leading to local maxima.
