Contents

• Install
• Training
• Evaluation

Install

1. Clone this repository and navigate to HallE_Control folder

git clone https://github.com/bronyayang/HallE_Control.git
cd HallE_Control

2. Install Package

conda create -n halle python=3.10 -y
conda activate halle
bash scripts/run.sh

Training

1. Prepare data

Follow LLaVA to prepare data. Download controller data here and put in ./data folder.

2. Start training

• Train controller: Model can output less hallucinated/more imagination captions based on $\epsilon$

bash scripts/v1_5/tune_controller.sh

Make sure the output_dir contains the word "controller" for correct inference behavior.

• Train indication: Model can output caption with [object] indication on imagined objects

bash scripts/v1_5/finetune_indication.sh

Evaluation

Here, we provide the procedure of evaluating any model on CCEval.

1. Download VisualGenome images part 1, part 2, and objects; unzip to ./data folder

2. Obtain captions of your model for 100 VG images. For example, you can obtain captions of controller model by using the following script:

bash scripts/v1_5/model_control_eval.sh

3. Get CCEval results (without coverage) by running:

python3 cceval.py --cap_file [YOUR_CAPTION_FILE_PATH] --key [YOUR_OPENAI_API_KEY]
