Model Card for LlavaNext BLP4k

This is a LlavaNext model finetuned on a synthetic dataset of bar, line, and pie charts. The goal is to detect if there is a misleading element in a chart image. The types of misleading elements that we propose are limited to: non-zero baseline for bar charts, omission of x-axis data points for line charts, and segments do not sum up to 100% in pie charts.

Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

How to Get Started with the Model

Use the code below to get started with the model. Only works on GPU

python

# Load model
from transformers import (
    AutoProcessor,
    LlavaNextForConditionalGeneration,
    BitsAndBytesConfig
)
from peft import PeftConfig, PeftModel
import requests
import torch

base_model = "llava-hf/llava-v1.6-mistral-7b-hf"
adapter_weights_repo = "chart-misinformation-detection/hf-llava-next-finetune-blp4k"

quantization_config = BitsAndBytesConfig(
    load_in_4bit=True, bnb_4bit_quant_type="nf4", bnb_4bit_compute_dtype=torch.float16
)

processor = AutoProcessor.from_pretrained(base_model)
model = LlavaNextForConditionalGeneration.from_pretrained(
    base_model,
    torch_dtype=torch.float16,
    quantization_config=quantization_config,
)

model = PeftModel.from_pretrained(model, adapter_weights_repo)

# preprocess input
prompt="[INST] <image>Evaluate if this chart is misleading, and if so explain [/INST]"
image = Image.open(requests.get(image_url, stream=True).raw)
inputs = processor(prompt, image, return_tensors="pt")

# inference
output = model.generate(**inputs, max_new_tokens=500)
print(processor.decode(output[0], skip_special_tokens=False))
