Product Information Extractor (Fine-tuned Gemma 1B IT)

This model is a fine-tuned version of unsloth/gemma-3-1b-it, optimized for extracting structured product information from noisy or unstructured descriptions.
It outputs a valid JSON object containing:

brand
product (2–3 words)
keywords (5 core keywords without quantity info)
quantity (normalized to number + unit)

Built as part of feature engineering for the Amazon ML Challenge 2025, it converts messy e-commerce listings into clean, ML-ready records.

⚡ Highlights

🧩 Base model: unsloth/gemma-3-1b-it
⚙️ Fine-tuning: LoRA + SFT using PEFT and TRL
🚀 VRAM usage: < 2 GB (VRAM-efficient)
⚡ Speed: Very fast inference
🧠 Output: Strict, deterministic JSON schema
🛍 Use case: Product data cleaning & feature extraction
