UniPrompt

About

UniPrompt looks at prompt optimization as that of learning multiple facets of a task from a set of training examples. UniPrompt, consists of a generative model to generate initial candidates for each prompt section; and a feedback mechanism that aggregates suggested edits from multiple mini-batches into a conceptual description for the section. In particular, it can generate long, complex prompts that baseline algorithms are unable to generate.

Installation

📋 Prerequisites

• Python 3 (>= 3.8)

1. Install the latest version of pip and setuptools

   python3 -m pip install --upgrade pip setuptools

2. To setup the package locally, run

   python3 -m pip install .

🔧 Setting up

1. Set Environment Variables

   OpenAI Endpoint: You need to set the OPENAI_API_KEY environment variable in the config before running the code.

2. Update the Config File

   Modify the config/dataset_name.json file as per your use case.

   If you are using an internal endpoint, make sure to set api_type to azure, api_base to your endpoint URL and api_version in your dataset config file. If you are using an OpenAI endpoint, then just set api_type to oai.

   The configuration includes the following parameters:

    "dataset_path": "data/ethos.jsonl",
    "mini_batch_size": 5,
    "batch_size": 7,
    "iterations": 1,
    "epochs": 5,
    "logging_file_path": "logs/ethos.jsonl",
    "epsilon": 0.5,
    "beam_width": 3,
    "group_frequency": 2,
    "cache_path": "cache/ethos.db",
    "initial_prompt": "<initial_prompt>",
    "metric_kwargs": {
        "type": "accuracy"
    },
    "solver_llm": {
        "model_kwargs": {
            "model": "gpt-4o",
            "temperature": 0,
            "max_tokens": 512,
            "stream": false
        },
        "api_kwargs": {
            "api_type": "",
            "api_base": "",
            "api_version": "",
            "api_key":"",
        }
    },
    "expert_llm": {
        "model_kwargs": {
            "model": "gpt-4",
            "temperature": 0,
            "max_tokens": 512,
            "stream": false  
        },
        "api_kwargs": {
            "api_type": "",
            "api_base": "",
            "api_version": "",
            "api_key":"",
        }
    },
    "grouping_llm": {
        "model_kwargs": {
            "model": "gpt-4",
            "temperature": 0,
            "max_tokens": 512,
            "stream": false
        },
        "api_kwargs": {
            "api_type": "",
            "api_base": "",
            "api_version": "",
            "api_key":"",
        }
    }

   Metric type can be one of ['accuracy', 'weighted_accuracy', 'hinge_accuracy'] Example config files can be found at config/ethos.json and config/bbh_navigate.json. Make sure to set api_kwargs before using them.

   A brief explanations on the config parameters:

   • dataset_path: Path to the dataset file
   • mini_batch_size: Number of examples processed in each mini-batch
   • batch_size: Number of mini-batches processed before updating the prompt
   • iterations: Number of times to iterate over the dataset in each epoch
   • epochs: Total number of training epochs
   • logging_file_path: Path to save the log file
   • epsilon: An exploration parameter with range [0, 1]
   • beam_width: Number of top-performing prompts to maintain in the beam search
   • group_frequency: Group questions every nth epoch
   • cache_path: Path to store/retrieve cached results
   • initial_prompt: The starting prompt for optimization

3. Prepare the Dataset

   The dataset format is very important. Ensure your dataset is a JSONL file with the following format:

   • split: (train, test, validation)
   • question: Full question that you want to get answered, including any prefix or postfix statements
   • choices: If the answer has choices, it should be a list, like [monkey, zebra, lion, tiger]
   • answer: The answer from the options

   Example:

   {"split": "train", "question": "What is the largest land animal?", "choices": ["monkey", "zebra", "lion", "tiger"], "answer": "tiger"}

🚀 Running the Optimization

For a working example, run
