LVSTCK/domestic-yak-8B

🐂 domestic-yak, a Macedonian LM (base version)

Model Summary

This model is a Macedonian language adaptation of the Llama 3.1 8B model. It has undergone continued pretraining on a deduplicated version of the Macedonian Corpus Raw dataset, containing approximately 1.6 billion tokens. The model has been pretrained for one epoch on this corpus, making it well-suited for tasks involving the Macedonian language, such as text classification, language generation, and translation.

📊 Results

The table below compares the performance of our model, domestic-yak-8B, with its foundational model, Llama 3.1-8B Instruct evaluated using the macedonian-llm-eval benchmark.

As shown in the table, domestic-yak-8B consistently outperforms its foundational model on all tasks.

Task (mk-version)	domestic-yak-8B	Llama 3.1-8B Instruct
ARC Easy	0.5244 ± 0.0102	0.4453 ± 0.0102
ARC Challenge	0.3183 ± 0.0136	0.2824 ± 0.0132
BoolQ	0.7676 ± 0.0074	0.7639 ± 0.0074
HellaSwag	0.4324 ± 0.0049	0.3740 ± 0.0048
Openbook QA	0.2920 ± 0.0204	0.2520 ± 0.0194
PIQA	0.6687 ± 0.0110	0.5865 ± 0.0115
NQ Open	0.0416 ± 0.0033	0.0335 ± 0.0030
WinoGrande	0.6259 ± 0.0136	0.5683 ± 0.0139

Quantitative evaluation is just one part of the story. We also conducted qualitative tests, interacting with the model to assess its ability to generate coherent and relevant responses in Macedonian. The results were satisfying: the model not only mastered the language's grammar but also demonstrated a natural and fluent style.

Here’s a comparison showing the answers from Llama-3.1-8B-Instruct and domestic-yak-8B:

• Llama-3.1-8B-Instruct:
  "Здраво! Секој пат кога го користиш оваа платформа, со тобе си во контакт со мојот систем на вештачка интелигенција. Мојот задача е да ти го обезбедам информативен и корисен одговор на секое прашање што можеш да ми го поставиш. Се нарекувам 'Асистент', и сум тука за да ти го правам живот полесен и интересниот. Што твоето прашање е?"

• domestic-yak-8B:
  "Здраво, јас сум асистент дизајниран да обезбеди информации и одговори на прашања од корисниците. Можам да одговарам на широк спектар на прашања, од општи факти и информации до специјализирани прашања во различни области. Мојата цел е да обезбедам точни и корисни одговори, како и да го олеснам процесот на пребарување и да заштедам време за корисниците. Слободно постави ми го твоето прашање и ќе се обидам да ти помогнам."

🔑 Key Details

• Language: Macedonian (mk)
• Base Model: Meta Llama 3.1 8B Instruct
• Dataset: LVSTCK/macedonian-corpus-raw-dedup (deduplicated version)
• Training Tokens: ~1.6 billion
• Pretraining Epochs: 1 epoch
• Pretraining Objective: Causal Language Modeling (continued pretraining using all the weights)

⚠️ Limitations

• Biases: The model may show biases present in the training dataset. Efforts were made to clean and deduplicate the corpus, but further bias mitigation might be necessary for sensitive applications.
• Domain Specificity: While the dataset covers diverse domains, performance may vary for niche or underrepresented topics. For example, the dataset is heavily skewed toward 'news'-themed texts, while domains such as 'science' or 'medicine' are less represented.
• Chat Capabilities: This version is the base model so its chat capabilities might be limited. If you would like to chat use the instruct version.
