# Model Card for identrics/wasper_propaganda_detection_en



## Model Description

- **Developed by:** [`Identrics`](https://identrics.ai/)
- **Language:** English
- **License:** apache-2.0
- **Finetuned from model:** [`google-bert/bert-base-cased`](https://huggingface.co/google-bert/bert-base-cased)
- **Context window :** 512 tokens

## Model Description

This model consists of a fine-tuned version of google-bert/bert-base-cased for a propaganda detection task. It is effectively a binary classifier, determining whether propaganda is present in the output string.
This model was created by [`Identrics`](https://identrics.ai/), in the scope of the WASPer project. The detailed taxonomy of the full pipeline could be found [here](https://github.com/Identrics/wasper/).


## Uses

Designed as a binary classifier to determine whether a traditional or social media comment contains propaganda.

### Example

First install direct dependencies:
```
pip install transformers torch accelerate
```

Then the model can be downloaded and used for inference:
```py
from transformers import AutoModelForSequenceClassification, AutoTokenizer

model = AutoModelForSequenceClassification.from_pretrained("identrics/wasper_propaganda_detection_en", num_labels=2)
tokenizer = AutoTokenizer.from_pretrained("identrics/wasper_propaganda_detection_en")

tokens = tokenizer("Our country is the most powerful country in the world!", return_tensors="pt")
output = model(**tokens)
print(output.logits)
```

## Training Details

The training dataset for the model consists of a balanced collection of English examples, including both propaganda and non-propaganda content. These examples were sourced from a variety of traditional media and social media platforms and manually annotated by domain experts. Additionally, the dataset is enriched with AI-generated samples.

The model achieved an F1 score of **0.807** during evaluation.

## Compute Infrastructure
This model was fine-tuned using a **GPU / 2xNVIDIA Tesla V100 32GB**.
