Sample Reinforcement Learning Assessments question Test your knowledge!

What term is used to describe the situation where a reinforcement learning agent starts performing worse on the task it is being trained on after continued training beyond a certain point?

  • Overfitting
  • Underfitting
  • Catastrophic forgetting
  • Bias-variance trade-off
  • Reward shaping

Which of the following is an accurate description of the Temporal Difference (TD) learning method in Reinforcement Learning?

  • TD learning is a Monte-Carlo method that requires complete episodes to update the value function.
  • TD learning combines ideas from Monte-Carlo methods and Dynamic Programming.
  • TD learning updates the value function only at the end of each episode, after obtaining the final reward.
  • TD learning is a model-based approach that uses the environment model to compute value functions.

In Reinforcement Learning, what does the 'exploration-exploitation dilemma' refer to?

  • The dilemma of choosing between model-based and model-free learning methods.
  • The conflict between learning the optimal policy and the computational resources required.
  • The trade-off between exploring new actions to find more rewarding strategies and exploiting known actions that yield high rewards.
  • The decision of whether to update the Q-value based on immediate or future rewards.

For a given state-action pair (s, a), what does the term Q(s, a) denote in the context of Q-Learning?

  • The probability of taking action 'a' in state 's'.
  • The expected cumulative reward of taking action 'a' in state 's', given a policy.
  • The immediate reward received after taking action 'a' in state 's'.
  • The expected cumulative reward of taking action 'a' in state 's' and following the optimal policy thereafter.

In deep reinforcement learning, the 'deadly triad' refers to three components that, when used together, can lead to instability or divergence. Which of the following is NOT one of the three components forming the 'deadly triad'?

  • Function Approximation
  • Bootstrapping
  • Off-policy learning
  • On-policy learning
  • Experience Replay

In reinforcement learning, what is the primary function of the 'exploration-exploitation trade-off'?

  • It determines the learning rate at which the Q-values converge.
  • It balances the need to explore new actions versus exploiting known rewarding actions.
  • It describes the method for initializing Q-values in model-free methods.
  • It is a rule for selecting the action with the highest expected reward.
  • It represents the compromise between model-based and model-free reinforcement approaches.
