"# Mini-GSM8K-Multilingual-Alignment\n",
"\n",
"A compact, multilingual DPO (Direct Preference Optimization) alignment dataset designed for training small language models to produce high-quality, step-by-step mathematical reasoning across multiple languages.\n",
"\n",
"## Purpose\n",
"\n",
"This dataset was created to improve multilingual math reasoning in small language models such as [Al-Khwarizmi-3B](https://huggingface.co/mzoelfakar/Al-Khwarizmi-3B) — a 3B-parameter math tutor model named after the 9th-century mathematician. The goal is to teach the model to prefer detailed, friendly, well-structured solutions over vague, uninformative responses, across 9 languages.\n",
"\n",
"## How It Was Created\n",
"\n",
"1. **Source**: 900 samples were drawn from [OpenAI/GSM8K](https://huggingface.co/datasets/openai/gsm8k) (socratic split), filtered to include only samples whose answers contain digits.\n",
"\n",
"2. **DPO Triplet Construction** (English):\n",
" - **Prompt**: The math problem\n",
" - **Chosen**: The full socratic step-by-step solution\n",
" - **Rejected**: The solution stripped of all English letters — leaving only digits, symbols, and whitespace — creating an abstract, vague, uninformative response\n",
"\n",
"3. **Multilingual Translation**: [gpt-oss-20b](https://huggingface.co/openai/gpt-oss-20b) (F16 GGUF from [unsloth/gpt-oss-20b-GGUF](https://huggingface.co/unsloth/gpt-oss-20b-GGUF), served with llama.cpp `llama-server` and parallel slots; temperature 0.7, reasoning effort medium) was used to translate the `prompt` and `chosen` columns into 8 languages (100 samples each), with careful instructions to:\n",
" - Preserve all mathematical symbols (`$`, `<<>>`, `####`, etc.)\n",
" - Add a brief, varying, friendly opening sentence to each solution\n",
" - Use context-aware translation (the model receives the original English problem when translating solutions)\n",
"\n",
"4. **English Samples**: The final 100 samples remain in English, with friendly opening sentences added to the solutions by the same model.\n",
"\n",
"## Language Distribution\n",
"\n",
"| Language | Code | Samples |\n",
"|----------|------|---------|\n",
"| Arabic | ar | 100 |\n",
"| French | fr | 100 |\n",
"| Spanish | es | 100 |\n",
"| German | de | 100 |\n",
"| Italian | it | 100 |\n",
"| Portuguese | pt | 100 |\n",
"| Chinese | zh | 100 |\n",
"| Russian | ru | 100 |\n",
"| English | en | 100 |\n",
"| **Total** | | **900** |\n",
"\n",
"## Schema\n",
"\n",
"| Column | Type | Description |\n",
"|--------|------|-------------|\n",
"| `prompt` | string | Math problem (translated to target language) |\n",
"| `chosen` | string | Full step-by-step solution with friendly opener (translated) |\n",
"| `rejected` | string | Digits-only stripped version of the original English solution |\n",
"| `language` | string | ISO 639-1 language code |\n",
"| `prompt_en` | string | Original English GSM8K problem that `prompt` was translated from |\n",
"| `chosen_en` | string | Original English GSM8K solution that `chosen` was translated from (without the friendly opener) |\n",
