# Model Card: BERT-Ohsumed

An in-domain BERT-base model, pre-trained from scratch on the Ohsumed dataset text.

## Model Details

### Description

This model is based on the [BERT base (uncased)](https://huggingface.co/google-bert/bert-base-uncased)
architecture and was pre-trained from scratch (in-domain) using the text in Ohsumed dataset, excluding its test split.
Only the masked language modeling (MLM) objective was used during pre-training.

- **Developed by:** [Cesar Gonzalez-Gutierrez](https://ceguel.es)
- **Funded by:** [ERC](https://erc.europa.eu)
- **Architecture:** BERT-base
- **Language:** English
- **License:** Apache 2.0
- **Base model:** [BERT base model (uncased)](https://huggingface.co/google-bert/bert-base-uncased)

### Checkpoints

Intermediate checkpoints from the pre-training process are available and can be accessed using specific tags,
which correspond to training epochs and steps:

| Epoch | Step | Tags | |
|---|---|---|---|
| 1 | 98 | epoch-1 | step-98 |
| 5 | 490 | epoch-5 | step-490 |
| 10 | 980 | epoch-10 | step-980 |
| 20 | 1960 | epoch-20 | step-1960 |
| 30 | 2940 | epoch-30 | step-2940 |
| 40 | 3920 | epoch-40 | step-3920 |
| 50 | 4900 | epoch-50 | step-4900 |
| 60 | 5880 | epoch-60 | step-5880 |
| 70 | 6860 | epoch-70 | step-6860 |
| 80 | 7840 | epoch-80 | step-7840 |
| 90 | 8820 | epoch-90 | step-8820 |
| 100 | 9800 | epoch-100 | step-9800 |

To load a model from a specific intermediate checkpoint, use the `revision` parameter with the corresponding tag:
```python
from transformers import AutoModelForMaskedLM

model = AutoModelForMaskedLM.from_pretrained("<model-name>", revision="<checkpoint-tag>")
```
