FinanceBERT

FinanceBERT is a transformer-based model specifically fine-tuned for sentiment analysis in the financial sector. It's designed to assess sentiments expressed in financial texts, aiding stakeholders in making data-driven financial decisions.

Model Description

FinanceBERT uses the BERT architecture, renowned for its deep contextual understanding. This model helps analyze sentiments in financial news articles, reports, and social media content, categorizing them into positive, negative, or neutral sentiments.

How to Use

To use FinanceBERT, you can load it with the Transformers library:

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

tokenizer = AutoTokenizer.from_pretrained('marcev/financebert')
model = AutoModelForSequenceClassification.from_pretrained('marcev/financebert')

def predict(text):
    inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True)
    outputs = model(**inputs)
    predictions = torch.nn.functional.softmax(outputs.logits, dim=-1)
    return predictions

text = "Your sample text here."
predict(text)

Limitations

FinanceBERT has been rigorously trained and tested to ensure reliable performance across a variety of financial texts. However, there are several limitations to consider:

Domain Specificity: Optimized for financial contexts, may not perform well on non-financial texts.
Language Support: Currently supports English only.
Data Bias: Reflects the bias inherent in its training data, which may not include diverse global financial perspectives.
Interpretability: As a deep learning model, it does not offer easy interpretability of its decision-making process.
