Model Card for Model ID

This is the MCQ confidence prediction model that outputs a certainty score given a math question and a full step-by-step rationale that attempts to solve the question.

Model Description

• Developed by: Shiyao Li
• Finetuned from model : meta-llama/Meta-Llama-3.1-8B

Model Example Usage

from transformers import AutoModelForSequenceClassification, AutoTokenizer
import torch

model_name_or_path = 'CarelessLee/MCQ_pooled_full_rationale_confidence_predictor'
model = AutoModelForSequenceClassification.from_pretrained(model_name_or_path)
tokenizer = AutoTokenizer.from_pretrained(model_name_or_path)

def predict(text):
    model.eval()
    inputs = tokenizer(text, return_tensors="pt")
    with torch.no_grad():
        outputs = model(**inputs)
    logits = outputs.logits
    certainty_score = logits.item()
    return certainty_score

def evaluate_predictor(label_data):
    for sample in tqdm(label_data, desc="Processing questions"):
        highest_score = -1
        best_rationale = ""
        for rationale in sample['rationales']:
            text = f"Problem: {sample['question']}\n---\nRationale Step: {rationale}"
            predicted_certainty_score = predict(text)
            print("predicted_certainty_score: ", predicted_certainty_score)

        label_data = json.load(f)
