Abstract: Given a task in the form of a basic description and its training examples, prompt optimization is the problem of synthesizing the given information into a text prompt for a large language model.Humans solve this problem by also considering the different facets that define a task (e.g., counter-examples, explanations, analogies) and including them in the prompt.However, it is unclear whether existing algorithmic approaches, based on iteratively editing a given prompt or automatically selecting a few in-context examples, can cover the multiple facets required to solve a complex task.In this work, we view prompt optimization as that of learning multiple facets of a task from a set of training examples.We exploit structure in the prompt optimization problem and break down a prompt into loosely coupled semantic sections.The proposed algorithm, UNIPROMPT, (1) clusters the input space and uses clustered batches so that each batch likely corresponds to a different facet of the task, and (2) utilizes a feedback mechanism to propose adding, editing or deleting a section, which in turn is aggregated over a batch to capture generalizable facets.Empirical evaluation on multiple datasets and a real-world task shows that prompts generated using UNIPROMPT obtain higher accuracy than human-tuned prompts and those from state-of-the-art methods.In particular, our algorithm can generate long, complex prompts that existing methods are unable to generate.Code for UNIPROMPT is available at https://aka.ms/uniprompt.
