# EconoSentiment
This model is a fine-tuned version of [samchain/econo-sentence-v2](https://huggingface.co/samchain/econo-sentence-v2) on the Financial Phrase Bank dataset from FinanceMTEB.
The full model is trained using a small learning rate isntead of freezing the encoder. Hence, you should not use the encoder of this model for a task other than sentiment analysis.
It achieves the following results on the evaluation set:
- Loss: 0.1293
- Accuracy: 0.962
- F1: 0.9619
- Precision: 0.9619
- Recall: 0.962
## Model description
The base model is a sentence-transformers model built from [EconoBert](https://huggingface.co/samchain/EconoBert).
## Intended uses & limitations
This model is trained to provide a useful tool for sentiment analysis in finance.
## Training and evaluation data
The dataset is directly downloaded from the huggingface repo of the FinanceMTEB. The preprocessing consisted of tokenizing to a fixed sequence length of 512 tokens.
## Training procedure
### Training hyperparameters
The following hyperparameters were used during training:
- learning_rate: 3e-05
