Walia-LLM: Enhancing Amharic-LLaMA by Integrating Task-Specific and Generative Datasets - combined data

Model Details

• Base model: LLaMA-2
• Fine-tuning method: Supervised fine-tuning (SFT) using LoRA
• Language: Amharic
• Tasks:
  • Sentiment analysis
  • Question answering
  • Named entity recognition
  • News classification
  • Summarization
  • Machine translation
  • Poem/story/lyrics generation
  • Spelling correction

Training Data

The model was trained on a custom instruction dataset derived from:

• Existing NLP benchmarks (e.g., AfriSenti, AmharicQA, MasakhaNER, MasakhaNews, XL-Sum)
• Manually collected generative datasets (e.g., religious lyrics, stories, poems)
• Translated instruction datasets (e.g., Alpaca, Dolly)

See EthioNLP/walia-amharic-instructions for the dataset used.

Intended Use

This model is intended for:

• Research on instruction tuning in low-resource languages
• Generative NLP tasks in Amharic
• Evaluating multilingual LLM capabilities

Limitations

• Some generative outputs may be verbose or imprecise.
• Limited understanding of highly specific Amharic poetic or lyrical structures.
• Spell correction and NER performance is still under exploration.

Example Usage

from transformers import AutoTokenizer, AutoModelForCausalLM

model = AutoModelForCausalLM.from_pretrained("israel/LLAMA-Walia-II")
tokenizer = AutoTokenizer.from_pretrained("israel/LLAMA-Walia-II")

prompt = "ስለ አማርኛ ቋንቋ መግለጫ አቅርብ።"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=100)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
