Comparing Penalty Function Implementations
In the context of controllable text generation, a penalty function can be designed in two primary ways: by assessing the final generated text (its surface form) or by assessing the model's internal hidden states during the generation process. Compare and contrast these two approaches. For each approach, provide one key advantage and one key disadvantage.

Penalty Functions Based on Hidden States
A developer is building a system to generate empathetic and cautious responses for a customer service chatbot. To achieve this, they want to implement a penalty function that discourages the model from adopting an 'overly confident' or 'assertive' internal state during the text generation process, rather than simply penalizing specific words in the final output. Which of the following penalty function designs best aligns with this goal of operating on the model's internal representations?
Comparing Penalty Function Implementations
A team is developing a text generation model and is considering two different ways to penalize undesirable outputs. Match each proposed penalty mechanism with the implementation approach it represents.
