  This is basically the German translation of arpanghoshal/EmoRoBERTa. We used
  the go_emotions dataset, translated it into German and fine-tuned the
  FacebookAI/xlm-roberta-base model. So this model allows the classification
  of 28 emotions in German Transcripts ('admiration', 'amusement', 'anger',
  'annoyance', 'approval', 'caring', 'confusion', 'curiosity', 'desire',
  'disappointment', 'disapproval', 'disgust', 'embarrassment', 'excitement',
  'fear', 'gratitude', 'grief', 'joy', 'love', 'nervousness', 'optimism',
  'pride', 'realization', 'relief', 'remorse', 'sadness', 'surprise',
  'neutral'). A paper will be published soonish...

# Model Card for G-E5-rman-Emotions

This is basically the German translation of arpanghoshal/EmoRoBERTa. We used the go_emotions dataset, translated it into German and fine-tuned the intfloat/multilingual-e5-large model. So this model allows the classification of **28 emotions** in German Transcripts (**'admiration', 'amusement', 'anger', 'annoyance', 'approval', 'caring', 'confusion', 'curiosity', 'desire', 'disappointment', 'disapproval', 'disgust', 'embarrassment', 'excitement', 'fear', 'gratitude', 'grief', 'joy', 'love', 'nervousness', 'optimism', 'pride', 'realization', 'relief', 'remorse', 'sadness', 'surprise', 'neutral'**). A paper will be published soonish...

## How to Get Started with the Model

Use the code below to get started with the model.

```python
# pip install transformers[torch]
# pip install pandas, transformers, numpy, tqdm, openpyxl
import pandas as pd
import torch
from transformers import AutoTokenizer, AutoModelForSequenceClassification, Trainer
import numpy as np

# create base path and input and output path for the model folder and the file folder
