# Impira Invoices Model Fine-tuned with CIVQA (EasyOCR) dataset
This is a fine-tuned version of the [Impira model](https://huggingface.co/impira/layoutlm-invoices), which was trained on Czech Invoice Visual Question Answering (CIVQA) datasets containing invoices in the Czech language.
This model enables Document Visual Question Answering on Czech invoices.
All invoices used in this dataset were obtained from public sources. Over these invoices, we were focusing on 15 different entities, which are crucial for processing the invoices.
- Invoice number
- Variable symbol
- Specific symbol
- Constant symbol
- Bank code
- Account number
- ICO
- Total amount
- Invoice date
- Due date
- Name of supplier
- IBAN
- DIC
- QR code
- Supplier's address
