🦢 Swin S3 Base (224) - Pascal VOC

A Swin S3 Base model fine-tuned on the Pascal VOC 2012 dataset for multi-class image classification.

---

🧠 Model Details

• Architecture: Swin S3 Base (224x224 input size)
• Pretrained on: ImageNet-1k
• Fine-tuned on: Pascal VOC 2012
• Framework: PyTorch (timm implementation)
• Format: safetensors

---

🎯 Intended Use

• Primary task: Image classification of natural scenes featuring objects from 20 Pascal VOC categories.
• Users: Researchers, developers working on computer vision applications, model benchmarking.
• Not intended for: Real-time decision making in critical applications (e.g., autonomous vehicles, medical diagnosis).

---

⚠️ Limitations and Ethical Considerations

• Biases: The model inherits biases present in Pascal VOC, such as underrepresentation of certain object types, contexts, or demographics. It may perform poorly on out-of-distribution samples.
• Ethical Use: Avoid using this model for applications that could reinforce harmful stereotypes, cause social harm, or violate privacy (e.g., surveillance).
• Transparency: This model is shared for research and educational use and should not be deployed without thorough fairness, robustness, and security evaluations.
