ASAG XLNet Regression Model

This model evaluates student answers by comparing them to reference answers and predicting a grade (regression).

Model Details

• Model Type: XLNet for Regression
• Task: Automatic Short Answer Grading (ASAG)
• Framework: PyTorch/Transformers
• Base Model: xlnet-base-cased
• Library: Transformers

Usage

from transformers import XLNetTokenizer, XLNetForSequenceClassification
import torch

# Load model and tokenizer
tokenizer = XLNetTokenizer.from_pretrained("kenzykhaled/XLENT_ASAG")
model = XLNetForSequenceClassification.from_pretrained("kenzykhaled/XLENT_ASAG")

# Prepare inputs
student_answer = "It is vision."
reference_answer = "The stimulus is seeing or hearing the cup fall."

inputs = tokenizer(
    text=student_answer,
    text_pair=reference_answer,
    return_tensors="pt",
    padding=True,
    truncation=True
)

# Get prediction
with torch.no_grad():
    outputs = model(**inputs)

# Get predicted grade (normalized between 0-1)
predicted_grade = outputs.logits.item()
predicted_grade = max(0, min(1, predicted_grade))
print(f"Predicted grade: {predicted_grade:.4f}")

Inference API Usage

This model can be used directly with the Hugging Face Inference API:

import requests

API_URL = "https://huggingface.co/proxy/api-inference.huggingface.co/models/kenzykhaled/XLENT_ASAG"
headers = {"Authorization": "Bearer YOUR_HUGGING_FACE_TOKEN"}

def query(payload):
    response = requests.post(API_URL, headers=headers, json=payload)
    return response.json()

data = {
    "inputs": {
        "source_sentence": "It is vision.",
        "sentences": ["The stimulus is seeing or hearing the cup fall."]
    }
}

result = query(data)
print(result)

Training Data

This model was trained on the Meyerger/ASAG2024 dataset.

Use Cases

• Automated grading of student short-answer responses
• Educational technology platforms
• Learning management systems
• Assessment tools
• Teacher assistance for grading

Limitations

• The model is trained on specific educational domains and may not generalize well to all subjects
• Performance depends on the similarity of input data to the training data
• Should be used as an assistive tool for grading rather than a complete replacement for human evaluation

Ethical Considerations

When using this model for automated grading:

• Be transparent with students about the use of AI for grading
• Consider potential biases in evaluation
• Provide human review of edge cases
• Allow students to appeal automated grades
