In this article, we will delve into the process of fine-tuning the Turkish QNLI model using the Turkish BERT model to tackle the Question-Answering (QA) tasks. This model has been specifically designed to work with the Turkish version of the SQuAD dataset, known as TQuAD. Whether you are a seasoned AI practitioner or just starting, we’ll guide you through the essentials to get you set up in no time!
What is the Turkish QNLI Model?
The Turkish QNLI (Question Natural Language Inference) Model is a specialized adaptation of BERT, optimized to handle questions and provide accurate answers based on the provided context. By leveraging the power of the TQuAD dataset, this model helps in evaluating the relevance of answers in relation to the posed questions.
Setting Up the Environment
Before diving into the fine-tuning process, ensure that your environment is correctly set up. Here’s how you can do this:
- Ensure you have Python installed (preferably version 3.6 or higher).
- Install PyTorch and Transformers libraries necessary for running BERT models.
- Clone the TQuAD dataset from its repository on GitHub.
- Download the Turkish BERT model from Hugging Face.
Preparing the Dataset
The TQuAD dataset is in JSON format, which we need to convert into the GLUE data format suitable for QNLI tasks. Here’s a simple analogy to digest this process:
Imagine you are sorting a box of assorted chocolates (the dataset) into neat rows based on flavor (GLUE data format). Each chocolate needs to be identified as either dark, milk, or white (entailment or not entailment), allowing the consumer to easily choose their preferred flavor (the answer). This step simplifies your main task, ensuring you can retrieve the right chocolate with ease (the correct answer) when needed.
Below is a script for converting the dataset:
import argparse
import collections
import json
import numpy as np
import os
import re
import string
import sys
ff = 'dev-v0.1.json'
ff = 'train-v0.1.json'
dataset = json.load(open(ff))
i = 0
for article in dataset[data]:
title = article[title]
for p in article[paragraphs]:
context = p[context]
for qa in p[qas]:
answer = qa[answers][0][text]
all_other_answers = list(set([e[answers][0][text] for e in p[qas]]))
all_other_answers.remove(answer)
i = i + 1
print(i, qa[question].replace(';', ':'), answer.replace(';', ':'), 'entailment', sep='\t')
for other in all_other_answers:
i = i + 1
print(i, qa[question].replace(';', ':'), other.replace(';', ':'), 'not_entailment', sep='\t')
Training the Model
Once your dataset is prepared, it’s time to train your model! Below are the step-by-step commands you’ll need to run:
- Set your environment variables for the GLUE directory and task.
- Execute the training with the following command:
export GLUE_DIR=.glue
glue_data=TRQNLI
export TASK_NAME=QNLI
python3 run_glue.py \
--model_type bert \
--model_name_or_path dbmdz/bert-base-turkish-uncased \
--task_name $TASK_NAME \
--do_train \
--do_eval \
--data_dir $GLUE_DIR \
--max_seq_length 128 \
--per_gpu_train_batch_size 32 \
--learning_rate 2e-5 \
--num_train_epochs 3.0 \
--output_dir tmp/$TASK_NAME
This command that instructs your model to learn from the training dataset is akin to sending your student on a journey to become a master chef. They first gather ingredients (data), followed by learning from recipes (model training) to eventually create exquisite dishes (accurate predictions).
Evaluating Your Model
After training, it’s essential to evaluate your model’s performance, so you can understand its efficacy:
- Check evaluation metrics: Accuracy and Loss. For instance, take note of an accuracy of around 91.24%.
Troubleshooting
If you encounter issues during your project’s life cycle, don’t fret! Here are some tips:
- Ensure your dataset is correctly formatted. A mismatch can cause errors.
- Double-check the installation of all prerequisites – sometimes missing libraries can stall your progress.
- Monitor the training logs for any insights on potential errors.
