Fine-tuning a pre-trained model can dramatically enhance its performance on specific tasks. In this article, we will explore how to fine-tune the Swin-Tiny model, a powerful transformer-based architecture designed for image classification. We’ll break down the process and the model’s training metrics, and provide some troubleshooting tips if you encounter issues.

Understanding the Swin-Tiny Model

The Swin-Tiny model operates differently from traditional models; it’s like a seasoned chef who uses a mix of various spices (transformers) to create a delicious dish (accurate predictions). By fine-tuning an already trained model, you’re allowing the chef to adjust the flavors based on specific ingredients (your dataset), leading to a more refined outcome.

Key Metrics from Training

This model is fine-tuned on the image folder dataset and has demonstrated remarkable results, achieving:

• Loss: 0.4504
• Accuracy: 0.9023

Model Configuration and Hyperparameters

Understanding the hyperparameters used during the training can help you optimize your model fine-tuning. Here’s a list of critical hyperparameters:

• Learning Rate: 5e-05
• Train Batch Size: 32
• Eval Batch Size: 32
• Seed: 42
• Gradient Accumulation Steps: 4
• Total Train Batch Size: 128
• Optimizer: Adam (beta values: 0.9, 0.999)
• LR Scheduler Type: Linear
• LR Scheduler Warmup Ratio: 0.1
• Number of Epochs: 130

Training Results

The training process was extensive and involved multiple epochs. The initial steps showcase a gradual improvement in accuracy while reducing loss:

0.4504         0.9023    0.1624         96.99   5044  0.4504           0.9023

Troubleshooting FAQs

If you encounter challenges while fine-tuning, here are some tips to resolve common issues:

• Model Not Converging: Check your learning rate and try using a smaller value.
• Overfitting: Consider integrating regularization techniques like dropout or weight decay.
• Memory Errors: Reduce batch size or use gradient accumulation to fit your model within your current resources.
