# Model Card: BERT-Sentiment140

An in-domain BERT-base model, pre-trained from scratch on the Sentiment140 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 Sentiment140 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 | 15000 | epoch-1 | step-15000 |
| 2 | 30000 | epoch-2 | step-30000 |
| 3 | 45000 | epoch-3 | step-45000 |
| 5 | 75000 | epoch-5 | step-75000 |
| 10 | 150000 | epoch-10 | step-150000 |
| 15 | 225000 | epoch-15 | step-225000 |
| 20 | 300000 | epoch-20 | step-300000 |
| 25 | 375000 | epoch-25 | step-375000 |

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>")
```
