The Predict-then-Refine Paradigm in NLP
The 'predict-then-refine' paradigm is a long-standing concept in Natural Language Processing where an initial output is generated and then iteratively improved. This approach has historical roots, with early examples including rule-based systems like Brill's tagger, and continues to be relevant in the modern deep learning era in various sequence-to-sequence tasks.

Solution as a Sequence of Reasoning Steps
A team is developing a system to solve complex mathematical word problems using a large language model. Their goal is to maximize the final answer's accuracy. Which of the following strategies best exemplifies a process where multiple potential solutions are first generated and then evaluated to select the most reliable one?
Analyzing LLM Reasoning Strategies
A system is designed to solve a complex problem by first generating multiple possible answers and then selecting the best one. Arrange the following steps to accurately represent this two-stage workflow.
In a system designed to solve a problem by first generating multiple potential solutions and then using a separate component to select the best one, the quality of the final selected answer depends solely on the generative capability of the initial model.

Self-Refinement in LLMs
An AI-powered code completion tool is designed to help developers write functions. When a developer provides a function name and a comment describing its purpose, the tool first generates a complete, functional block of code. Following this initial generation, the tool enters a loop where it analyzes the code it just wrote, identifies potential inefficiencies or non-standard practices, and applies a specific correction. This analysis-and-correction loop repeats several times, with the code block being progressively improved at each step. Which statement accurately characterizes the fundamental approach this tool uses?
