🧬 ViDRiP-LLaVA: A Dataset and Benchmark for Diagnostic Reasoning from Pathology Videos

ViDRiP-LLaVA is a vision-language framework designed for instruction-based diagnostic reasoning using both image patches and video clips from pathology slides. It builds on LLaVA and extends it to the medical domain with domain-specific datasets and fine-tuned models.

🧠 Introducing our ViDRiP-LLaVA: the first multimodal model for diagnostic reasoning in pathology through video-based instruction. 🔬📽️

Our method leverages chain-of-thought (CoT) prompting to distill the reasoning capabilities of LLMs. ViDRiP-LLaVA generates both detailed histological descriptions and final diagnoses, simulating how pathologists analyze and sign out cases.

📚 Trained on 4,278 instructional video pairs

⚙️ Combines single-image + clip transfer and fine-tuning on segmented diagnostic videos

📚 Video Datasets

🎥 Released Video Format

All clips are:

• Cleaned using a Visual Data Refinement pipeline (temporal trimming + YoloPath filtering + OCR exclusion + inpainting)
• Downsampled to 1–5 FPS to reduce file size and support fair-use compliance
• Muted to avoid redistribution of original YouTube audio

These steps preserve diagnostic signal while respecting the rights of YouTube creators and complying with YouTube’s Terms of Service.

🔍 Training vs. Public Release Notice

The ViDRiP-LLaVA models were trained on an internal dataset version that included:

• Full-frame-rate video clips
• Visual content prior to OCR filtering

All evaluations (including those in our benchmark) are conducted using the publicly released test set, ensuring full reproducibility.

🔹 ViDRiP_Instruct_Train

The videos data is ~ 60 GB:

🔹 ViDRiP_Instruct_Train_Video_Hugging Face (There is 6 zip files)

• 4,000+ instruction-style samples
• Each sample includes:
  • A pathology video clip
  • A diagnostic question
  • A multi-turn reasoning answer
• Format: JSON + MP4
• Croissant-compliant metadata for structured use

🔹 ViDRiP_Instruct_Test

🔹 ViDRiP_Instruct_Test_Video

• Held-out test set of diagnostic Q&A pairs
• Used for benchmarking reasoning performance

📚 Image Datasets

We use publicly available datasets: Quilt-LLaVA and PathAsst. Please refer to their respective repositories for download instructions.

• Quilt-LLaVA: A vision-language dataset for pathology adapted from LLaVA.
• PathAsst: A generative assistant for pathology with curated image-text pairs.

🚀 Quickstart

🔧 Fine-tuning the model on video dataset

./scripts/train/finetune_ov_video.sh

🪄 Fine-tuning with LoRA

./scripts/train/finetune_ov_video_lora.sh

🔗 Merge LoRA weights

./scripts/train/merge_lora_weights.py

🧪 Usage / Demo

./doc/ViDRiP_LLaVA_trial.py

🔧 Evaluate on our video dataset

We use lmms_eval to evaluate the performance of video diagnostic reasoning.

To benchmark ViDRiP-LLaVA and compare it with other models:

1. Clone the lmms_eval repo
2. Copy our evaluation task folder into it:

cp -r lmms_eval/tasks/ViDRiP_Instruct_Test /path/to/lmms_eval/tasks/

You can then run evaluation using the standard lmms_eval CLI interface.
