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://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
