Introduction

Hello everyone, I'm excited to share my personal project with you, which involves fine-tuning DocLayout-YOLO for credit card statement layout analysis. As I begin this project, I'd like to seek your guidance on two crucial aspects: class definitions and training strategies. Your expertise will help me create a robust model that accurately identifies the structure of credit card statements.

Recommended Classes

When it comes to annotating classes for financial documents, I plan to start with the following labels:

  • credit_summary_table
  • usage_level
  • transactions_table
  • logo_*

However, I'm curious to know if there are any suggested label sets for financial documents that I can leverage. Should I build upon the existing classes from DocLayNet/DocStructBench or create my own custom labels?

Existing Label Sets

DocLayNet and DocStructBench have already established label sets for financial documents. These sets may provide a solid foundation for my project. Some of the existing labels include:

  • header
  • footer
  • table
  • image
  • text

While these labels are a good starting point, I'm unsure if they cover all the necessary aspects of credit card statements. I'd like to know if there are any additional labels that I should consider or if I should modify the existing labels to suit my project's requirements.

Custom Label Sets

If I decide to create my own custom labels, I'll need to ensure that they are comprehensive and accurately represent the structure of credit card statements. This may involve identifying specific fields, such as:

  • account_balance
  • payment_due_date
  • minimum_payment
  • interest_rate

By creating a custom label set, I can tailor the model to my specific needs and improve its accuracy.

Training Strategy

Now that I've discussed class definitions, let's move on to the training strategy. Should I train the model from scratch or fine-tune a pre-trained model, such as doclayout_yolo_docstructbench_imgsz1024.pt?

Training from Scratch

Training a model from scratch can be a time-consuming process, but it allows me to start with a blank slate and create a model that's tailored to my specific needs. This approach may be beneficial if I have a large dataset and want to experiment with different architectures and hyperparameters.

Fine-Tuning a Pre-Trained Model

Fine-tuning a pre-trained model, on the other hand, can save me a significant amount of time and computational resources. By leveraging a model that's already been trained on a large dataset, I can focus on fine-tuning the model to my specific task and dataset. This approach may be beneficial if I have a smaller dataset or want to quickly experiment with different architectures and hyperparameters.

Conclusion

In conclusion, I'd like to thank you for your time and expertise. Your guidance on class definitions and training strategies will help me create a robust model that accurately identifies the structure of credit card statements. I look forward to hearing your thoughts and advice on this matter.

Recommended Next Steps

Based on our discussion, I recommend the following next steps:

  1. Review the existing label sets from DocLayNet/DocStructBench and consider modifying them to suit my project's requirements.
  2. Create a custom label set that accurately represents the structure of credit card statements.
  3. Fine-tune a pre-trained model, such as doclayout_yolo_docstructbench_imgsz1024.pt, to my specific task and dataset.

By following these steps, I'll be able to create a robust model that accurately identifies the structure of credit card statements and provides valuable insights for my project.
