Which of the following is a common reinforcement learning algorithm used in NLP?

  1. Q-learning

  2. SARSA

  3. Policy Gradients

  4. Actor-Critic


Correct Option: C
Explanation:

Policy Gradients are a class of reinforcement learning algorithms that directly optimize the policy function, rather than learning a value function.

What is the goal of reinforcement learning in NLP?

  1. To learn a policy that maps input sequences to output sequences

  2. To learn a model that predicts the next word in a sequence

  3. To learn a model that translates one language to another

  4. To learn a model that generates text


Correct Option: A
Explanation:

The goal of reinforcement learning in NLP is to learn a policy that maps input sequences to output sequences, such as in machine translation or text generation.

Which of the following is a common application of reinforcement learning in NLP?

  1. Machine Translation

  2. Text Summarization

  3. Question Answering

  4. Dialogue Generation


Correct Option:
Explanation:

Reinforcement learning is used in a variety of NLP applications, including machine translation, text summarization, question answering, and dialogue generation.

What is the main challenge in applying reinforcement learning to NLP?
