This is [RuBERT-tiny2](https://huggingface.co/cointegrated/rubert-tiny2) model fine-tuned for __sentiment classification__ of short __Russian__ texts.
The task is a __multi-class classification__ with the following labels:

```yaml
0: neutral
1: positive
2: negative
```

Label to Russian label:

```yaml
neutral: нейтральный
positive: позитивный
negative: негативный
```

## Usage

```python
from transformers import pipeline
model = pipeline(model="seara/rubert-tiny2-russian-sentiment")
model("Привет, ты мне нравишься!")
# [{'label': 'positive', 'score': 0.9398769736289978}]
```

## Dataset

This model was trained on the union of the following datasets:

- Kaggle Russian News Dataset
