For the task of unsupervised fine-tuning a language model like ai-forever/mGPT-1.3B-azerbaijan
, the dataset needs to be prepared in a specific format that allows the model to learn from the text effectively. Here’s a detailed breakdown of how you should format your dataset:
The goal is to format your dataset so that each entry (line or paragraph) provides a self-contained piece of text which the model will use to predict the next words. The model essentially learns the structure of the language by trying to predict the next word in the sequence given the previous words.

Content Structure:
Encoding:
Examples:
Imagine a dataset with simple news snippets, stories, or sentences in Azerbaijani. Here's how you might structure the file:
Bakının mərkəzində yeni park salınır.
Sabah hava necə olacaq?
Azərbaycanın iqtisadiyyatı son illərdə sürətlə inkişaf edir.
Ən yaxşı dostumla kafeə gedəcəyik.
Dünya çempionatında milli komandamız uğurlu çıxış etdi.
Each line is a complete sentence, providing the model with various examples of Azerbaijani syntax and vocabulary.
Tokenization: Before training, this text will be tokenized. The tokenizer converts each sentence into a series of tokens (numerical representations), which are then used by the model for training.
Batching: During training, these tokens are batched into groups (determined by the batch_size
in your training arguments). The model learns by predicting the next token in each batch.
Imagine you're illustrating this dataset preparation process:

Fine-tuning the
ai-forever/mGPT-1.3B-azerbaijan
model on your extensive Azerbaijani corpus is an excellent way to enhance the model’s capability in Azerbaijani. Since you’re looking to do this in an unsupervised manner, typically this would involve language modeling or a similar task where the model learns to predict the next word or sequence of words based on the previous context. Here’s how you can approach this:Step 1: Set Up Your Environment
Ensure you have a suitable environment set up for handling a large model like mGPT-1.3B. You will need:
Step 2: Prepare Your Dataset
Step 3: Load the Pre-trained Model and Tokenizer
You will start by loading the model and its corresponding tokenizer.
Step 4: Tokenize Your Data
Convert your text data into a format suitable for model input.
Step 5: Define Training Arguments
Set up the training parameters using Hugging Face’s
TrainingArguments
.Step 6: Start Training
Initiate the training process to fine-tune the model on your Azerbaijani text corpus.
Step 7: Save and Evaluate the Model
After training, save your model and evaluate its performance.
Evaluate the model using qualitative tests (like generating text) or quantitative metrics (like perplexity if you have a validation set).
Conclusion
This approach fine-tunes the
ai-forever/mGPT-1.3B-azerbaijan
model in an unsupervised manner to improve its performance on Azerbaijani text. It leverages the existing pre-trained capabilities of the model and enhances it with domain-specific knowledge from your text corpus. Ensure to monitor the training for any potential issues, such as overfitting or resource constraints.
