# EmTract (DistilBERT-Base-Uncased) |
|
|
|
## Model Description |
|
|
|
`emtract-distilbert-base-uncased-emotion` is a specialized model finetuned on a combination of [unify-emotion-datasets](https://github.com/sarnthil/unify-emotion-datasets), containing around 250K texts labeled across seven emotion categories: neutral, happy, sad, anger, disgust, surprise, and fear. This model was later adapted to a smaller set of 10K hand-tagged messages from StockTwits. The model is designed to excel at emotion detection in financial social media content such as that found on StockTwits. |
|
|
|
Model parameters were as follows: sequence length of 64, learning rate of 2e-5, batch size of 128, trained for 8 epochs. For steps on how to use the model for inference, please refer to the accompanying Inference.ipynb notebook. |
|
|
|
## Training Data |
|
|
|
The training data was obtained from the Unify Emotion Datasets available at [here](https://github.com/sarnthil/unify-emotion-datasets). |
|
|
|
## Evaluation Metrics |
|
|
|
The model was evaluated using the following metrics: |
|
- Accuracy |
|
- Precision |
|
- Recall |
|
- F1-score |
