Idefices2-EDGAR

Idefices2 8B fine-tuned on 800+ multi-page documents for Visual DocQA. Make sure you have the latest peft and transformers before loading the model. GPU is required for it to work properly.

Compared to the base model, it has a lower edit distance (53% improvement on micro average) on the test set.

SEC Contract QA

Training Procedure

10 epochs with QLoRA. Trained with A100-80GB for about 10 hours. Code: Github.

MAX_LENGTH = 1024
USE_LORA = False
USE_QLORA = True
MAX_PAGE = 5

config = {
    "max_epochs": 10,
    # "val_check_interval": 0.2,
    "check_val_every_n_epoch": 1,
    "gradient_clip_val": 1.0,
    "accumulate_grad_batches": 12,
    "lr": 1e-4,
    "batch_size": 2,
    "precision": "16-mixed",
    "seed": 42,
    "warmup_steps": 50,
    "result_path": "./result",
    "verbose": True,
}

Preprocessing [optional]

No image splitting due to memory limit.

processor = AutoProcessor.from_pretrained(
    "HuggingFaceM4/idefics2-8b",
    do_image_splitting=False,
    size={"longest_edge": 490, "shortest_edge": 350}
)
