roberta_base

This is a fine-tuned RoBERTa model for question-answering classification tasks.

Model Details

• Base Model: roberta-base
• Model Type: Sequence Classification
• Language: English
• License: Apache 2.0

Model Information

• Number of Classes: 5
• Classification Type: grouped_classification
• Class Names: Empty, Word, Short, Medium, Long

Usage

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

# Load model and tokenizer
tokenizer = AutoTokenizer.from_pretrained('whitedevil0089devil/roberta_base')
model = AutoModelForSequenceClassification.from_pretrained('whitedevil0089devil/roberta_base')

# Example usage
question = "Your question here"
inputs = tokenizer(question, return_tensors="pt", truncation=True, padding=True, max_length=384)

with torch.no_grad():
    outputs = model(**inputs)
    predictions = torch.nn.functional.softmax(outputs.logits, dim=-1)
    predicted_class = torch.argmax(outputs.logits, dim=-1).item()
    confidence = predictions[0][predicted_class].item()

print(f"Predicted class: {predicted_class}")
print(f"Confidence: {confidence:.4f}")

Training Details

This model was fine-tuned using:

• Framework: PyTorch + Transformers
• Optimization: AdamW with learning rate scheduling
• Training Strategy: Early stopping with validation monitoring
• Hardware: Trained on Google Colab (T4 GPU)

Intended Use

This model is designed for question-answering classification tasks. It can be used to:

• Classify questions into predefined categories
• Provide automated responses based on question classification
• Support Q&A systems and chatbots

Limitations

• Model performance depends on the similarity between training data and inference data
• May not generalize well to domains significantly different from training data
• Classification accuracy may vary based on question complexity and length
