M-014Few-Shot Product Classifier
Description
Nebula Corp's e-commerce platform receives thousands of product listings daily, but they're uncategorized. The current zero-shot classifier is inconsistent — sometimes 'wireless headphones' goes to Electronics, sometimes to Audio, sometimes to Accessories. Build a few-shot prompt constructor that uses 3 diverse examples to teach the model the exact categorization rules. The examples must cover edge cases and demonstrate the distinction between similar categories.
