Image classification is a pivotal task in the field of computer vision. With the advent of deep learning, fine-tuning pre-trained models has become a popular method for achieving high accuracy in image recognition tasks. In this guide, we will walk through the steps to fine-tune the Swin Tiny model on your image dataset, review the results, and address potential troubleshooting issues.

Understanding the Model

The Swin Tiny Patch 4 model is a pre-trained vision transformer that has been adapted for image classification. We will be fine-tuning this model on the EuroSAT dataset, using various training parameters to optimize performance.

Getting Started

To fine-tune the Swin Tiny model, follow these steps:

• Install Required Libraries: Make sure you have the latest versions of libraries like `Transformers`, `PyTorch`, and `Datasets` installed.
• Prepare Your Dataset: Your dataset should be organized in the image folder format, with different folders for each category.
• Set Hyperparameters: Use the predefined hyperparameters in our training procedure to ensure optimal training results.

Training Procedure

Your training procedure should closely mimic the following:

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 with betas=(0.9,0.999) and epsilon=1e-08
lr_scheduler_type: linear
lr_scheduler_warmup_ratio: 0.1
num_epochs: 200

Training Results

Your training results will indicate how well your model has learned from the data. Here are the key results:

• Final Loss: 5.6236
• Final Accuracy: 0.4528

This indicates that the model has learned but still has room for improvement, as an accuracy of approximately 45% suggests there’s potential for fine-tuning or changing hyperparameters.

Analogy: Think of Fine-Tuning as a Cooking Process

Imagine you are a chef preparing a gourmet dish. You start with a basic recipe (the pre-trained model) but need to make it your own. You taste the dish at various stages (the training epochs), making adjustments (the hyperparameters) as needed. If it’s too bland (low accuracy), you might add spices (optimize further) until you achieve a flavor that delights your guests (better accuracy). Just like cooking, finding the right balance can take time and patience!

Troubleshooting

If you encounter issues during training, consider the following tips:

• Ensure that your dataset is correctly formatted.
• Monitor the performance metric over each epoch for signs of underfitting or overfitting.
• Adjust hyperparameters like learning rate and batch sizes tactfully — don’t be afraid to experiment!
• Check for library version compatibility with your PyTorch installation.
