Introduction

This repository focuses on enhancing the honesty and helpfulness of Large Language Models (LLMs) in real-world applications. Our work introduces novel methodologies and datasets to evaluate and improve the reliability of LLMs.

Components

• HoneSet Dataset: A novel dataset containing 930 queries across six categories, crafted to evaluate the honesty of LLMs.

• Two Enhancement Approaches:

  • Training-Free Enhancement: Leverages curiosity-driven prompting to help LLMs express uncertainty and refine their responses.
  • Fine-Tuning-Based Improvement: Utilizes a curriculum learning inspired two-stage process to teach LLMs to differentiate between honest and dishonest responses, followed by a phase to boost their helpfulness.

HoneSet

• Honeset is located in dataset/HoneSet.json which contains 930 data items across 6 categories as follows:

Category
Latest Information with External Services
User Input Not Enough Or With Wrong Information
Self Identity Cognition
Modality Mismatch
Professional Capability in Specific Domain
Interactivity Sensory Processing

Training-free Enhancement

Requirements

• Python 3.x
• Libraries: openai, replicate, requests, tenacity, concurrent.futures, anthropic, torch, yaml, argparse, dotenv
• API keys and model mappings for Azure, replicate, deepinfra and other services.

Configuration Steps

• Edit Configuration:
  • Navigate to the training_free/config.yaml file.
  • Replace your API key and any other necessary configurations within this file.
• Script Location:
  • Ensure that you are in the directory containing the training_free.sh script.
• Set Model Parameters:

  • model_type can be online or local

  • model_name can be as follows:

    Model_name input	Model
    gpt-4	GPT-4
    chatgpt	ChatGPT
    claude	Claude3-Opus
    llama3-70b	Llama3-70b
    llama3-8b	Llama3-8b
    mixtral-8x7b	Mixtral-8x7b
    llama2-7b	Llama2-7b
    llama2-13b	Llama2-13b
    llama2-70b	Llama2-70b
    mistral-7b	Mistral-7b

Command Line Arguments

• Online Mode When running the script in online mode, use the following parameters:

./training_free.sh online [model_name]

• local Mode When running the script in local mode, you can specify additional parameters:
• --temperature (default = 0): Controls the randomness of the response generation. Higher values produce more varied outputs.
• --repetition_penalty (default = 1.0): Penalizes repetition to encourage more diverse responses.
• --num_gpus (default = 1): Specifies the number of GPUs to use.
• --max_length (default = 2048): Limits the number of tokens in the response.
• --debug (default = false): Enables debug mode for more verbose output.
• --model_path (default = ''): The path to the model files, necessary in local mode.
• --filename (default = ''): Specifies the output filename.
• --test_type (default = 'plugin'): Sets the type of testing or processing.
• --online (default = 'False'): Indicates whether to run the model in online mode.

./training_free.sh local [model_name] --temperature [value] --repetition_penalty [value] --num_gpus [value] --max_length [value] --debug --model_path [path] --filename [filename] --test_type [type] 

Improvement through fine-tuning

Overview

This repository contains scripts and configurations for fine-tuning, merging, and running inference with Llama models using LLaMA-Factory.

Requirements

• LLaMA-Factory installed
• Install LLaMA-Factory

git clone --depth 1 https://github.com/hiyouga/LLaMA-Factory.git
cd LLaMA-Factory
pip install -e .[torch,metrics]

Run Fine-tuning

Fine-Tuning

To fine-tune the model, use the following command:

llamafactory-cli train train_config.yaml

Replace train_config.yaml with one setting in finetuning/*.yaml

Merging Stage 1 Model

After fine-tuning, merge the stage 1 model using:

llamafactory-cli export merge_lora_dpo.yaml

Make sure merge_lora_dpo.yaml is configured with the appropriate merging parameters.

Running Model Inference

To run model inference, execute:

llamafactory-cli api model_inference.yaml

Ensure model_inference.yaml contains the correct inference settings.
