🧠 Llama-3.2-1B-Instruct — IMB Neurologia Fine-Tuned Model
This model is a fine-tuned version of
unsloth/Llama-3.2-1B-Instruct-unsloth-bnb-4bit, optimized for
Italian medical question answering, with a specific focus on
Neurologia.
The fine-tuning was performed using a subset of the IMB (Italian Medical Benchmark) dataset, specifically:
- Neurologia category only
- ~10,000 training samples
The training was performed using the Unsloth library with LoRA fine-tuning, and the adapter weights were later merged into the base model to provide a standalone checkpoint.
This model relies on data from the IMB dataset. If you use this model in research or applications, you must cite the IMB paper (see Citation section below).
📚 Training Dataset — IMB (Italian Medical Benchmark)
IMB is an Italian benchmark for medical question answering, designed to evaluate and improve LLM performance in clinical-domain Italian language understanding and reasoning.
The full dataset includes:
- IMB-QA: 782,644 doctor-patient conversations collected from Italian online medical forums
- IMB-MCQA: 25,862 multiple-choice questions derived from Italian medical specialization exams
⚠️ Important:
This model was trained only on the Neurologia subset (~10,000 samples) of IMB, not on the full dataset.
