BERT-Base-Uncased Quantized Model for Sentiment Analysis for Student Feedback Analysis

This repository hosts a quantized version of the BERT model, fine-tuned for stock-market-analysis-sentiment-classification 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: Sentiment Analysis for Student Feedback Analysis
Dataset: Stanford Sentiment Treebank v2 (SST2)
Quantization: Float16
Fine-tuning Framework: Hugging Face Transformers

Usage

Installation

pip install transformers torch

Loading the Model

python

from transformers import BertForSequenceClassification, BertTokenizer
import torch

# Load quantized model
quantized_model_path = "AventIQ-AI/sentiment-analysis-for-student-feedback-analysis"
quantized_model = BertForSequenceClassification.from_pretrained(quantized_model_path)
quantized_model.eval()  # Set to evaluation mode
quantized_model.half()  # Convert model to FP16

# Load tokenizer
tokenizer = BertTokenizer.from_pretrained("bert-base-uncased")

# Define a test sentence
test_sentence = "Overall, the course was a valuable learning experience. The instructor was knowledgeable and always willing to answer questions, which made complex topics easier to understand. However, the lectures sometimes felt rushed, and there was not enough time allocated for in-depth discussions. The assignments were well-designed and helped reinforce the concepts, though some of them were a bit too lengthy for the given deadlines. I appreciated the feedback provided on my submissions, as it helped me identify areas for improvement. Despite a few issues, I feel more confident in the subject now than when I started."

# Tokenize input
inputs = tokenizer(test_sentence, return_tensors="pt", padding=True, truncation=True, max_length=128)

# Ensure input tensors are in correct dtype
inputs["input_ids"] = inputs["input_ids"].long()  # Convert to long type
inputs["attention_mask"] = inputs["attention_mask"].long()  # Convert to long type

# Make prediction
with torch.no_grad():
    outputs = quantized_model(**inputs)

# Get predicted class
predicted_class = torch.argmax(outputs.logits, dim=1).item()
print(f"Predicted Class: {predicted_class}")


label_mapping = {0: "very_negative", 1: "nagative", 2: "neutral", 3: "Positive", 4: "very_positive"}  # Example

predicted_label = label_mapping[predicted_class]
print(f"Predicted Label: {predicted_label}")

Performance Metrics

Accuracy: 0.82

Fine-Tuning Details

Dataset

The dataset is taken from Kaggle Stanford Sentiment Treebank v2 (SST2).

Training

Number of epochs: 3
Batch size: 8
Evaluation strategy: epoch
Learning rate: 2e-5

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.
