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

```yaml
0: no_emotion
1: joy
2: sadness
3: surprise
4: fear
5: anger
```

Label to Russian label:

```yaml
no_emotion: нет эмоции
joy: радость
sadness: грусть
surprise: удивление
fear: страх
anger: злость
```

## Usage

```python
from transformers import pipeline
model = pipeline(model="seara/rubert-tiny2-cedr-russian-emotion")
model("Привет, ты мне нравишься!")
# [{'label': 'joy', 'score': 0.9605025053024292}]
```

## Dataset

This model was trained on [CEDR dataset](https://huggingface.co./datasets/cedr).

An overview of the training data can be found in it's [Hugging Face card](https://huggingface.co./datasets/cedr) 
or in the source [article](https://www.sciencedirect.com/science/article/pii/S1877050921013247).

Training were done in this [project](https://github.com/searayeah/bert-russian-sentiment-emotion) with this parameters:

```yaml
tokenizer.max_length: null
batch_size: 64
optimizer: adam
lr: 0.00001
