Albert For Arqmath 3

🚀 ALBERT for ARQMath 3

This repository provides our top - performing model for ARQMath 3, which can effectively handle math - related question - answer matching and ranking tasks.

🚀 Quick Start

This repository contains our best model for ARQMath 3, the math_10 model. It was initialised from ALBERT - base - v2 and further pre - trained on Math StackExchange in three different stages. We also added more LaTeX tokens to the tokenizer to enable a better tokenization of mathematical formulas. math_10 was fine - tuned on a classification task to determine whether a given question (sequence 1) matches a given answer (sequence 2). The classification output can be used for ranking the best answers. For further details, please read our paper: [http://ceur - ws.org/Vol - 3180/paper - 07.pdf](http://ceur - ws.org/Vol - 3180/paper - 07.pdf).

✨ Features

Other Models for ARQMath 3

We plan on also publishing the other fine - tuned models as well as the base models. Links to these repositories will be added here soon.

Update

We have also further pre - trained a BERT - base - cased model in the same way as our ALBERT model. You can find it here: AnReu/math_pretrained_bert.

💻 Usage Examples

Basic Usage

# based on https://huggingface.co/docs/transformers/main/en/task_summary#sequence-classification
from transformers import AutoTokenizer, AutoModelForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("AnReu/albert-for-arqmath-3")

model = AutoModelForSequenceClassification.from_pretrained("AnReu/albert-for-arqmath-3")

classes = ["non relevant", "relevant"]

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 $(a+b)^2=a^2+2ab+b^2$"

# The tokenizer will automatically add any model specific separators (i.e. <CLS> and <SEP>) and tokens to
# the sequence, as well as compute the attention masks.
irrelevant = tokenizer(sequence_0, sequence_2, return_tensors="pt")
relevant = tokenizer(sequence_0, sequence_1, return_tensors="pt")

irrelevant_classification_logits = model(**irrelevant).logits
relevant_classification_logits = model(**relevant).logits

irrelevant_results = torch.softmax(irrelevant_classification_logits, dim=1).tolist()[0]
relevant_results = torch.softmax(relevant_classification_logits, dim=1).tolist()[0]

# Should be irrelevant
for i in range(len(classes)):
    print(f"{classes[i]}: {int(round(irrelevant_results[i] * 100))}%")

# Should be relevant
for i in range(len(classes)):
    print(f"{classes[i]}: {int(round(relevant_results[i] * 100))}%")
