BERT-Base-Uncased Quantized Model for customer feedback sentiment analysis

This repository hosts a quantized version of the bert-base-uncased model, fine-tuned for social media sentiment analysis tasks. The model has been optimized for efficient deployment while maintaining high accuracy, making it suitable for resource-constrained environments.

Model Details

Model Architecture: BERT Base Uncased
Task: Social Media Sentiment Analysis
Dataset: Social Media Sentiments Analysis Dataset [Kaggle]
Quantization: Float16
Fine-tuning Framework: Hugging Face Transformers

Usage

Installation

pip install transformers torch

Loading the Model


from transformers import BertForSequenceClassification, BertTokenizer
import torch
device = 'cuda' if torch.cuda.is_available() else 'cpu'

# Load quantized model
model_name = "AventIQ-AI/sentiment_analysis_for_customer_feedback"
model = BertForSequenceClassification.from_pretrained(model_name).to(device)
tokenizer = BertTokenizer.from_pretrained(model_name)

#Function to make analysis
def predict_sentiment(text):
    # Tokenize input text
    inputs = tokenizer(text, return_tensors="pt", truncation=True, padding=True, max_length=512)
    
    # Move tensors to GPU if available
    inputs = {key: val.to(device) for key, val in inputs.items()}

    # Get model prediction
    with torch.no_grad():
        outputs = model(**inputs)
    
    # Get predicted class
    logits = outputs.logits
    predicted_class = torch.argmax(logits, dim=1).item()

    # Map back to sentiment labels
    sentiment_labels = {0: "Negative", 1: "Neutral", 2: "Positive"}
    return sentiment_labels[predicted_class]

# Define a test sentence
test_sentence = "Spending time with family always brings me so much joy."
print(f"Predicted Sentiment: {predict_sentiment(text)}")

Fine-Tuning Details

Dataset

The dataset is taken from Kaggle Social Media Sentiment Analysis.

Training

Quantization

Post-training quantization was applied using PyTorch's built-in quantization framework to reduce the model size and improve inference efficiency.

Limitations

The model may not generalize well to domains outside the fine-tuning dataset.
Quantization may result in minor accuracy degradation compared to full-precision models.
