Dataset Description

This early-stage dataset contains spatial annotations for surgical instrument localization in pituitary surgery. It served as a proof-of-concept for the spatial localization task.

Key Features

🎯 Spatial Coordinates: Normalized (x, y) coordinates in 0-100 scale
🔧 Surgical Instruments: Basic instrument categories
🧪 Prototype Phase: Early development version
📊 Limited Coverage: Subset of complete surgical workflow

Historical Context

This dataset was created during the initial development phase of the PitVQA spatial localization project. It helped establish:

Feasibility of spatial localization with VLMs
Coordinate format (normalized 0-100 scale)
Question-answering structure for spatial queries
Baseline performance metrics

Migration Guide

Upgrading to Comprehensive Version

If you're currently using this dataset, migration is straightforward:

# Old (Early Version)
from datasets import load_dataset
dataset_old = load_dataset("mmrech/pitvqa-spatial-vlm")

# New (Comprehensive Version) - Recommended
dataset_new = load_dataset("mmrech/pitvqa-comprehensive-spatial")

# Same format, just more data and better validation!

Training Configuration

For LoRA training, use the same configuration as the comprehensive version:

from trl import SFTTrainer
from peft import LoraConfig

lora_config = LoraConfig(
    r=16,
    lora_alpha=32,
    target_modules=["q_proj", "v_proj", "k_proj", "o_proj"],
    lora_dropout=0.05,
    bias="none",
    task_type="CAUSAL_LM",
)

However, we recommend training on the comprehensive version for better performance.

Performance Comparison

Early Version (This Dataset)

Metric	Value
Quadrant Accuracy	~35-40%
Coordinate MAE	~18-20%
Status	Baseline

Comprehensive Version (Recommended)

Metric	Value	Improvement
Quadrant Accuracy	80.3%	+124%
Coordinate MAE	12.1%	-40%
Status	State-of-the-art	✅

Performance increase: Models trained on the comprehensive version achieve 124% improvement in quadrant accuracy.

Use Cases

Appropriate Use Cases

Historical Research: Understanding evolution of spatial VLMs
Ablation Studies: Comparing data quantity effects
Baseline Comparisons: Establishing improvement metrics
Educational Demos: Simple proof-of-concept examples

Not Recommended For

❌ Production models (use comprehensive version)
❌ MICCAI/journal publications (use comprehensive version)
❌ Clinical research (use comprehensive version)
❌ Benchmark evaluations (use comprehensive version)

Training Usage

Recommended Approach

Don't train on this dataset. Instead:

# Use the comprehensive version
from datasets import load_dataset

dataset = load_dataset("mmrech/pitvqa-comprehensive-spatial")

# Follow training guide:
# https://github.com/matheus-rech/pit_project/blob/main/notebooks/train_spatial_qwen2vl_colab.ipynb

If You Must Use This Dataset

from datasets import load_dataset

# Load early version (not recommended)
dataset = load_dataset("mmrech/pitvqa-spatial-vlm")

# Same training procedure as comprehensive version
# But expect lower performance (35-40% vs 80.3%)

Limitations

Dataset Limitations

Limited Samples: Smaller dataset than comprehensive version
Incomplete Coverage: Not all surgical phases covered
Partial Validation: Not fully validated for ground truth fidelity
Lower Performance: Models trained on this achieve 35-40% accuracy vs 80.3%

Technical Limitations

Data Quality: Less rigorous validation than comprehensive version
Documentation: Limited compared to production dataset
Support: Community support focused on comprehensive version

Superseded Status

⚠️ This dataset has been superseded by mmrech/pitvqa-comprehensive-spatial
