Understanding complex mathematical problems and deriving precise answers is a task made significantly easier with the help of AI models like ALBERT. In this blog, we will explore how to use the ALBERT model specifically fine-tuned for Mathematics Answer Retrieval. This will allow you to generate relevance scores to rank the answers to your mathematical queries effectively.

What is ALBERT for Math AR?

The ALBERT model for Math Answer Retrieval is based on the ALBERT base v2 architecture and has been pre-trained on Mathematics StackExchange questions and answers. This model utilizes a sequence classification head to output a relevance score when you input a question and potential answers. It’s essentially an AI detective helping you to sift through the noise and find the right answers!

Usage Instructions

Here’s how to set up and utilize the ALBERT model in Python:

• First, you need to install the necessary libraries and import them in your Python environment.
• Use the AutoTokenizer and AutoModelForSequenceClassification features from the Transformers library.
• Prepare your sequences for analysis.
• Utilize the model to get logits and compute relevance scores for your answers.

Step-by-Step Code Implementation

Below is the code snippet you’ll need to run this AI model:

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained('albert-base-v2')
model = AutoModelForSequenceClassification.from_pretrained('AnReualbert-for-math-ar-base-ft')

# Define classes
classes = ['non relevant', 'relevant']

# Create sequences
sequence_0 = "How can I calculate x in $3x = 5$"
sequence_1 = "Just divide by 3: $x = \\frac{5}{3}$"
sequence_2 = "The general rule for squaring a sum is $(a+b)^2=a^2+2ab+b^2$"

# Tokenize sequences
irrelevant = tokenizer(sequence_0, sequence_2, return_tensors='pt')
relevant = tokenizer(sequence_0, sequence_1, return_tensors='pt')

# Get classification logits
irrelevant_classification_logits = model(**irrelevant).logits
relevant_classification_logits = model(**relevant).logits

# Compute softmax to get probabilities
irrelevant_results = torch.softmax(irrelevant_classification_logits, dim=1).tolist()[0]
relevant_results = torch.softmax(relevant_classification_logits, dim=1).tolist()[0]

# Display results
for i in range(len(classes)):
    print(f'{classes[i]}: {int(round(irrelevant_results[i] * 100))}%')

for i in range(len(classes)):
    print(f'{classes[i]}: {int(round(relevant_results[i] * 100))}%')

Understanding the Code: A Mathematical Detective Analogy

Think of the ALBERT model as a detective in a math mystery world. Here’s how the code components fit together:

• AutoTokenizer: Acts like a translator, breaking down your complex mathematical sentences into a language that the model understands.
• Sequences: The mysteries to unravel—the questions and possible answers set for investigation.
• model: Your detective, evaluating the sequences and determining if they hold relevance to the case at hand.
• softmax: The detective’s skill to assess probabilities, allowing them to decide which answer is most likely relevant.

Troubleshooting

If you encounter issues while setting up or running the code, consider these troubleshooting tips:

• Ensure all dependencies, particularly the Transformers and Torch libraries, are installed properly.
• Check that your Python environment is configured correctly to avoid version mismatches.
• If your model fails to load, verify the model name and its availability in the Hugging Face model hub.
