Colab-based experiments for multilingual maternal, sexual, and reproductive health question answering in low-resource African languages.
# Multilingual Health QA Notebooks
Colab experiment tracker for multilingual health question answering in low-resource African languages.
## Goal
The task is to generate accurate, fluent, and contextually appropriate health answers in the same language as the input question. The challenge focuses on low-resource African languages including Akan/Twi, Luganda, Kiswahili, and Amharic, alongside English subsets from several countries.
## Evaluation
Use a weighted multi-metric score:
| Metric | Weight | Purpose |
| --- | ---: | --- |
| ROUGE-1 F1 | 0.37 | Keyword and unigram overlap |
| ROUGE-L F1 | 0.37 | Sentence-level sequence similarity |
| LLM-as-a-Judge | 0.26 | Factuality, completeness, and language appropriateness |
Prediction files contain these columns for evaluation:
```text
ID, TargetRLF1, TargetR1F1, TargetLLM
```
## Current Baseline
Current public leaderboard experiment log:
| Run | Model | Setup | ROUGE-L F1 | ROUGE-1 F1 | LLM Judge | Weighted PLB Score |
| --- | --- | --- | ---: | ---: | ---: | ---: |
| `gemma4-e4b-zero-shot-v1` | `google/gemma-4-E4B-it` | Zero-shot, Colab GPU | 0.3663 | 0.6071 | 0.6133 | 0.5196 |
| `gemma4-26b-a4b-zero-shot-v1` | `google/gemma-4-26B-A4B-it` | Zero-shot, Colab GPU | 0.3655 | 0.6277 | 0.7720 | 0.5682 |
Runtime note: the run took about 3 hours and used roughly 15 GB RAM in the Colab environment.
## Experiment Roadmap
1. Establish zero-shot Gemma 4 E4B-it baseline.
2. Try larger Gemma 4 variants, starting with `google/gemma-4-26B-A4B-it`.
3. Compare prompt variants on stratified validation samples before full test generation.
4. Add retrieval-based baselines to improve ROUGE-style lexical overlap.
5. Move to QLoRA fine-tuning only after baseline and retrieval runs are well understood.
