In the age of artificial intelligence, fine-tuning a pre-trained model can significantly enhance its performance on specific tasks. Today, we’ll explore how to fine-tune the muhtashambert-tiny-mlm-finetuned-imdb model for text classification using the IMDB dataset. This guide will walk you through the essential steps, training parameters, and results you can expect!

Understanding the Fine-Tuning Process

Imagine you have a very knowledgeable chef (the pre-trained model) who can cook a variety of cuisines but specializes in Italian. You want them to whip up a perfect local dish. To achieve this, you provide them with the recipe and ingredients specific to that local dish (the IMDB dataset), training them over a few cooking sessions (epochs) to get the flavors just right.

In our context, the chef is the model, the recipe is the task of text classification based on movie reviews, and the ingredients are the data we feed into it!

Model Specifications

The fine-tuned model, dubbed finetuned-self_mlm_mini, achieved the following results during evaluation:

• Loss: 0.6150
• Accuracy: 0.8224
• F1 Score: 0.9025

Training Procedure

The training process is where the magic happens! Below are the hyperparameters used to shape our model:

• Learning Rate: 3e-05
• Train Batch Size: 128
• Eval Batch Size: 128
• Seed: 42
• Optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08

Troubleshooting Tips

If you encounter issues during the fine-tuning process, here are some troubleshooting ideas:

• Check if your dataset is properly formatted.
• Ensure that all dependencies are correctly installed, including Transformers 4.25.1, Pytorch 1.12.1+cu113, Datasets 2.7.1, and Tokenizers 0.13.2.
• If the training doesn’t seem to improve, consider adjusting your learning rate or increasing the number of epochs.
