This repo contains a low-rank adapter (LoRA) for BLOOM-7b1 fit on the Stanford-Alpaca-52k and databricks-dolly-15k data in Urdu.

Dataset Creation

1. English Instructions: The English instuctions are obtained from alpaca-52k, and dolly-15k.
2. Instruction Translation: The instructions (and inputs) are translated into the target languages using Google Translation API (conducted on April 2023).
3. Output Generation: We generate output from gpt-3.5-turbo for each language (conducted on April 2023).

Training Parameters

The code for training the model is provided in our github, which is adapted from Alpaca-LoRA. This version of the weights was trained with the following hyperparameters:

• Epochs: 8
• Batch size: 128
• Cutoff length: 1024
• Learning rate: 3e-4
• Lora r: 16
• Lora target modules: query_key_value

That is:

python finetune.py \
    --base_model='bigscience/bloom-7b1' \
    --num_epochs=5 \
    --cutoff_len=1024 \
    --group_by_length \
    --output_dir='./bactrian-ur-bloom-7b1-lora' \
    --lora_target_modules='query_key_value' \
    --lora_r=16 \
    --micro_batch_size=32

Instructions for running it can be found at https://github.com/MBZUAI-nlp/Bactrian-X.

Discussion of Biases

(1) Translation bias; (2) Potential English-culture bias in the translated dataset.
