🏦 LAPEFT: Financial Sentiment Analysis

A fine-tuned BERT model with LoRA for financial sentiment analysis. This model classifies financial text into three categories: Negative, Neutral, and Positive.

Model Details

• Base Model: bert-base-uncased
• Fine-tuning: LoRA (Low-Rank Adaptation)
• Classes: 3 (Negative, Neutral, Positive)
• Domain: Financial text analysis
• Language: English

Usage

Quick Start with Pipeline

from transformers import pipeline

# Load the model
classifier = pipeline(
    "text-classification", 
    model="Hananguyen12/LAPEFT-Financial-Sentiment-Analysis"
)

# Analyze sentiment
text = "The company reported strong quarterly earnings."
result = classifier(text)
print(result)
# Output: [{'label': 'POSITIVE', 'score': 0.9234}]

Advanced Usage

from transformers import BertTokenizer, BertForSequenceClassification
from peft import PeftModel

# Load model components
base_model = BertForSequenceClassification.from_pretrained(
    "bert-base-uncased", 
    num_labels=3
)
model = PeftModel.from_pretrained(base_model, "Hananguyen12/LAPEFT-Financial-Sentiment-Analysis")
tokenizer = BertTokenizer.from_pretrained("bert-base-uncased")

# Inference
text = "The quarterly results exceeded expectations."
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=512)

with torch.no_grad():
    outputs = model(**inputs)
    predictions = torch.nn.functional.softmax(outputs.logits, dim=-1)
    predicted_class = torch.argmax(predictions, dim=-1)

labels = ["NEGATIVE", "NEUTRAL", "POSITIVE"]
print(f"Predicted: {labels[predicted_class]}")

Model Performance

• Optimized for financial text analysis
• Efficient LoRA fine-tuning approach
• Suitable for real-time sentiment analysis

Use Cases

• Financial news sentiment analysis
• Social media monitoring for financial content
• Investment research and analysis
• Risk assessment based on sentiment

Limitations

• Trained primarily on English financial text
• Performance may vary on non-financial content
• Best suited for sentences and short paragraphs
